Introduction Under our present civilization, industrial developments will be greatest in those areas in which energy .can be most economically produced and efficiently used, where labour is in adequate supply, and where markets for the products of industry are available. A knowledge of fuels- the present major sources of energy- and of their utilization is therefore of vital importance. With that in mind, the aim in this paper will be to outline the known reserves of fuels in Alberta, to give their characteristics, to indicate the markets served by each, and to offer some suggestions for the future development of the coal industry. The paper should be regarded as a compilation of published data rather than as an original treatise. Alberta is richly blessed by having large reserves of mineral fuels. The estimated reserves of coal are 46,562 million tons. Alberta is the oil and gas province of Canada. The world's largest deposit of bituminous sand occurs along the Athabaska river in Alberta. In addition, there are large areas of forested land in the northern and western sections of the Province, and the rivers serve for the development of hydro-power.

Over the last four years, an international initiative, championed by Vehicle Projects LLC, the Fuelcell Propulsion Institute and Natural Resources Canada, has been active in carrying out research projects to prove out the concept of applying fuelcell technology to underground mining vehicles. These have been carried out by a consortium consisting of mining companies, equipment manufacturers, technology developers, national laboratories and consultants, with the participation of Canadian and U.S. mine regulatory agencies. This clean technology, which produces only water and electricity, would allow several advantages to be obtained, in the health area (by eliminating diesel emissions and reducing noise generation), in lowering production costs (such as reducing ventilation required) and lowering green house gas emissions. This article outlines the results obtained in several key areas, such as the operation of fuelcells in underground conditions, risk issues related to underground and surface operation of hydrogen vehicles and hydrogen production and delivery systems, and the design and mining performance of the world?s first hydrogen mining vehicle, a mine production locomotive. The work to date on the fuelcell loader, designing the power plant and power transmission systems, operational requirements, and operating cost reductions, is also presented. There is also an evaluation of the overall mining applications and advantages this technology can bring to underground mining, including the facilitation of automation and tele-remote operation.

Introduction The technical library in the service of industry is gradually becoming a well recognized and important part of all progressive industrial organizations. The larger mining, metallurgical, and chemical firms of Canada are establishing extensive reference libraries in connection with their research and operating departments in order that the members of the organization may keep abreast of the rapidly developing fields of engineering in which they are interested. It is the purpose of this paper to point out the usefulness of such a department in any industrial organization, to give a general outline of a system for filing and dispensing information, and to outline briefly the literature to be consulted and the procedure to be adopted in instigating a literature search. The technical library falls under the classification known as 'Special Libraries', and is quite different from the general library in that it is a storehouse of facts and owes its value to the ready presentation of information required for each specific case, and in a form most ready for use. The library brings all the available information relative to the interests of the corporation from without the plant to the organization within, and also keep in touch with each department of the organization.

"IntroductionBACK IN THE nineteen-thirties, when Eldorado was a private company and was preparing to become Canada's first radium producer, the Mines Branch in Ottawa did much work on the development of chemical processes for the Port Hope refinery (1).In 1945, after the Canadian Government had taken over Eldorado for •atomic energy reasons, the Mines Branch was called upon again, this time to help out by looking into ways and means of improving ore treatment methods for the mine at Great Bear Lake. A group of technical men was assembled to devote full attention to this work, which was known as the Eldorado Project.Three years later, in 1948, the Government decided to reopen the development and operation of uranium properties to private enterprise.Since it is a function of the Mines Branch to assisit private development of Canadian mineral resources, this new uranium policy made it important for the Branch to be in a position where it could provide up-to-date services, technical assistance, and information relating to treatment of radioactive ores, mineralogy of radioactive ores, and assay methods for radioactive ores.At the same time, .because of the demand for increased uranium production, lower grade ores had definitely come into the picture, ores that might be of decidedly lower grade than, say, Eldorado pitchblende, and of entirely different nature."

THIS paper is an endeavour to analyse the ideal and practical functions of government technical mining services, and their relationship to the National Domain, as well as to one another. its spirit is not critical, even though at times it may appear to besoin fact. It is a serious effort to divert a trend in public thought which delights in calling itself practical whereas it is really merely short-sighted. The author refers particularly to the idea that governmental research is a luxury which should be curtailed in the interests of economy, and turned over to private enterprise or the provinces. In order that we obtain the proper perspective of the question, it is advisable to indulge in a little history. In the year 1842, the Geological Survey of Canada was formed under the guidance of William (later Sir William) Edmund Logan. The literature on the founding and history of the Geological Survey of Canada is extensive, and therefore it is unnecessary to go into detail here regarding it. It might be mentioned, however, that the Geological Survey of Canada is only seven years younger than the Geological Survey of Great Britain (founded in 1835), and is only exceeded in age on the American continent by the State Geological Surveys of New York, Pennsylvania, Massachusetts, and Michigan, which were founded between 1833 and 1836. In 1877, the Geological Survey became a permanent government institution as a branch of the Department of the Interior. It should be noted, however, that the Director of the Survey ranked as a Deputy Minister and reported direct to the Minister. This continued until 1907. In 1886, the Mineral Resources and Statistics Division of the Geological Survey was formed. Some years later, the Canadian Institute of Mining and Metallurgy (then the Canadian Mining Institute), backed by the mining press, began to agitate for the establishment of a Dominion Department of Mines, and in 1907 such a department was founded by the Geology and Mines Act of that year, with a separate Cabinet portfolio for the position of Minister of Mines.

DR. W. F. GRAY (Contributed discussion, presented at meeting by Mr. S. C. Mifilen): Mr. Rowe's suggestion that the Institute should organize itself to interpret the needs of the mining industry to federal and provincial mines departments should commend itself to our membership as sensible and practical, and as one which these public administrative bodies may welcome. One has to start with the premise that those who head the departments of mines in question have the welfare of the industry at heart. Also, it must be postulated that the technical viewpoint of our membership is necessarily free of political considerations. With these reservations, one ventures to state that both Mr. Rowe in his communication to the present session of the Institute, and Professor M. Y. Williams in his earlier communication to the Western Meeting, on The Geological Survey and Mining Development (1), voice the regret general among our membership at the abandonment of the honoured name, and to some extent of the status, of the Geological Survey of Canada. The writer, in 1932, devoted his Presidential Address to the Institute to an appreciation of the value to Canadian mining of the Geological Survey of Canada (2), affirming the desire of the Institute "that the work of the Survey shall be maintained at the highest pitch of efficiency the resources of our country will permit, because, to scrimp expenses on the Survey, is 'to save at the spigot and lose at the bunghole'." He believes that is still the opinion of the Institute, and, if contraction of the usefulness of the Survey is feared by our members at this time, it is incumbent upon the Institute, in fairness to those who direct our government, to say so in precise and explicit terms. Mr. Rowe puts the situation pithily when he writes: "We have reached a stage in our development where a stock-taking and co-ordination of existing knowledge and data is essential. This is a part of that basic function of Dominion mineral technical services which is national and not provincial in its scope".

"In mineral exploration and mining applications, it is sometimes necessary to reduce sampling error in order to improve representivity of individual sample assays. Historic efforts to reduce sampling error have relied on the belief that larger samples exhibit less sampling error. Justifications for this belief traditionally have coupled the binomial theorem with an ideal geological material consisting of ore and gangue particles of equal size and shape (an equant grain model) and empirical tests of geological materials, to illustrate an inverse relationship between sample size and sampling variance. To date, no proof exists of this sample size-sampling variance relationship in real geological materials exhibiting variations in grain size, shape, composition, and degree of liberation.Using first principles calculus and the formula for the mean, sample mass and sampling variance are proven to be inversely proportional in all geological materials. Distribution assumptions and physically ideal geological models are not used in this proof. Furthermore, algebraic manipulations of expressions describing the variances of equant grain models consistent with binomial, hypergeometric, and Poisson distributions reveal that these models also exhibit an inverse sample size-sampling variance relationship. Thus, the sampling behaviors of these models are numerically consistent with the sampling behaviors of real geological materials, and these models can be used to estimate sampling errors in real geological materials using simple sampling parameters."

"This paper explores the history of AC static variable frequency control drive systems on open cast mining machinery, in particular electric mining shovels and electric walking draglines, over the past ten years. It critiques the peformance of these drive systems from a productivity and operating cost standpoint and evaluates the over-all success of the original design concepts as they were envisaged in the 1970s. The paper details the state-of-the-art as it exists today as well as design improvements contemplated for the immediate future.IntroductionConsidering the fact that the very first successful application of an alternating current electrical distribution system occurred at the Gold King gold mine near Ames, Colorado, U.S.A., in the year 1891, it seems somewhat ironic that almost 100 years later, AC excavator drive systems are just now becoming commonplace in the mining industry.If one were to read the biography of Lucien L. Nunn, the first person to successfully install a commercially viable alternating current power distribution system, one would quickly visualize a parallelism between his fight to achieve acceptance of his new lower cost technology and that of those commissioned with the belief that AC static variable frequency control drive systems are not only a better performing, lower cost drive system for mining excavators today, but moreover, the drive systems of the future in our industry.This paper will deal with the evolution and incorporation of AC static drive systems on open cast mining excavators. It will trace the history of the development of these drive systems in the mining industry, the current state-of-the-art concerning these systems, and what the future holds for these excavators in our industry."

At the Annual General Meeting of the Institute in 1924. I endeavoured to present the position held by the mineral industries in the commercial life of this country. The facts and figures were presented at that time in a detached way. Since then, however, I have made some attempt to analyze them in order to determine the causes for that position and to draw some conclusions as to the future of the mining industry. As everyone knows, our trade figures are very often used in political discussion, especially in discussion of tariff policy. It would be entirely out of order for me to say anything touching the tariff issue and I want to have it clearly understood that, in my opinion, the material I am about to present contains not a single statement or conclusion which anyone would be warranted in using as an argument for either a lower or a higher tariff or for tariff changes of any kind. As a starting point, let me re-state, very sketchily, Canada's general situation in external trade. In the last calendar year, 1924, we sold Canadian merchandise of all kinds to other countries to the value of $1,045,000,000 in round figures. Our purchases abroad reached about $893,000,000. Thus our sales exceeded our purchases by roughly $152,000,000. In other words, we had what is known as a 'favourable balance of trade' - one of the biggest favourable balances we have ever had in our history. The proceeds of our sales of Canadian products enabled us to meet the bills for all our purchases of foreign commodities and, in addition, placed a large surplus to our credit with which to offset our interest charges and other obligations abroad.

This paper gives an estimation of the future requirements of the western world in relation to energy re-sources. It then goes on to outline the role that atomic power -with its basic raw material, uranium -will play in supplying these energy requirements. Canada's position in this picture is covered, and some interesting forecasts are made. Introduction I T is possible that the following remarks will appear to have more to do with power than uranium. However, to fully comprehend what is in store for the Canadian uranium mining industry, we must be able to estimate the potential requirement, and, to do this satisfactorily, a thorough understanding of the circumstances that will give rise to that demand is necessary. The growing need for electrical energy will play by far the major role, as large tonnages of uranium will be required for its generation. The nuclear weapon has, up to the present, comprised the major market for uranium.

"This paper summarizes the present-day usage of computers in the mining-metallurgical industry. The industry appears to be following a path taken by other industries in improving the operation of processing plants, production schedules, grade control and haulage performance. A reduction in the cost of computers and computing has been a significant factor.An attempt is made to forecast the future of computers in our industry. Such developments as time-sharing, mini-computers, and easy-to-understand process-oriented languages will lead to wider usage. Considerable strides have been made in the use of computers for laboratory data acquisition. In general, the implementation of new methods, new techniques and new equipment will require plant personnel to develop new skills. The universities are meeting this challenge by re-structuring curricula and offering special courses. Most vendors of computers already offer special courses within their own facilities at a customer's plant."

ABSTRACT The Saskatchewan Ministry of Environment recognizes the importance of environmental protection as an important contributor to Saskatchewan’s economy, with the environmental performance of industry closely monitored. Unfortunately, environmental regulation is often accompanied by significant process that does not always add value to environmental protection activities. The Saskatchewan Ministry of Environment has embarked on a visionary restructuring of its regulatory framework from conventional command and control regulation to a results-based regulatory framework. This new regulatory framework will provide for establishing clear environmental protection and resource management objectives; streamlining the environmental acts and regulations; developing an environmental code of practice; relying on qualified persons; enhancing compliance and enforcement tools; eliminating of many permits; and developing greater certainty in environmental assessment decisions. Results-based regulation promises to deliver enhanced environmental protection with less process. The uranium industry in Saskatchewan will be used as an example of the potential effects of results-based regulation.

For the period January 1st, 1942, to January 1st, 1946, the American Bureau of Metal Statistics records the gold production of the world as 118,788,000 fine ounces. If we include 1946 at the same rate as 1945 (26,- 590,000), we arrive at a total of 145,378,000 fine ounces in the past five years . Included in these figures are estimates of Russian output at 4,000,000 ounces per annum for the five years, and 1,300,000 ounces per annum for Korea and Japan. The remaining 120,000,000 ounces represent the aggregate production from official reports of the other gold producing areas of the world, with the exception of the 1946 figures, as noted above. At $35.00 per fine ounce, this represents $5,188,230,000. According to the reports of the Federal Reserve System of the United States, on December 31st, 1941, the monetary gold reserves of the United States were $22,736,- 600,000 (at $35.00 per fine ounce) , while on October 31st, 1946 (latest available) , they had fallen to $20,402,000,000, a decline of $2,334,600,000. Adding this decline to the value of the new production for the five years, we have a total of $7,522,830,000, which has been absorbed by the rest of the world since Pearl Harbour, a rate of absorption of over $1,500,000,000 per annum. This has taken place at a rime when the advocates of purely managed currencies had convinced many people that gold performed no really essential function in the world's economy, and that we could get along perfectly well without it. It was pointed out that gold could not be eaten, it could not clothe our nakedness, it could not shelter us from storms, and, therefore, it was a non-essential, even though it could be used to settle international balances of trade. Apparently, the world as a whole still regards it as preferable to the paper promises of governments, however sound, relatively, they may appear. Actually, we have no way of measuring the true strength of this feeling, because the principal governments of the world have made it legally impossible for their citizens to own gold, except in the form of ornaments.

Gold-based materials have been a mainstay of the electronics and semiconductor industry since the physics was just a laboratory curiosity. Gold is the workhorse material in wire bond, flip chip and off wafer interconnections due to its corrosion resistance, ability to form metallurgical bonds by soldering or cold welding, and ease of fabrication. As the electronics and semiconductor industries grew, so did the use, of Gold in spite of the feature size reduction so elegantly demonstrated in Moore?s law. However, several revolutions in the Silicon miracle are threatening Gold?s place as the material of choice. Although cost is always an issue, the limitations are associated with the chemistry of Gold based alloys. Will Gold remain? Emerging requirements of bioelectronics, photonics and power requirements in conventional device represent new opportunities for Gold to shine. Additionally, as the world market demand for electronic, semiconducting, bio-electronic and photonic technology increases, given the right technology, Gold still can provide value proposition.

"AFTER SPENDING a lifetime in the mining industry it is normal that one should be concerned with the future of his profession, especially if he is directly responsible for the education and formation of future mining engineers. It is not necessary to insist on the importance of mining for Canada and for the entire world to prove the necessity of the Mining Engineer. A statement was made by Zay Jeffries, former vicepresident of General Electric Co., and here I quote: ""Even though minerals without man are of no moment, man would not be man as we know him without minerals ... ""minerals are as essential to the life of social man as food is to man himself"". This certainly expresses magnificently the purpose of the mining profession. These are the reasons why I have accepted to present my views on the future of the Mining Engineer. If I express some concern it is not because I feel that there is any danger for the profession to disappear; men will always respond to a challenge and this can be found in the extraction of minerals as well as in any other field of human endeavour. However, the first big question concerns the competitive position of Canada in the world of mining. To be made available to Canadians and to the rest of the world, all this tremendous potential mineral wealth that our country has been so generously endowed with by nature must be gained from the earth's crust at a competitive cost. Otherwise it will never become ore and will have no value. Let us not forget that although minerals are discovered, mines are not found but are made. So let us be more efficient mine makers. To accomplish this end, it is the duty of the different responsible organizations at all levels - be they governmental, para-governmental, public or private institutions - to do their utmost to assure the profitable development of our mineral wealth. The University has an all-important role to play in preparing all the specialists required by this intricate machine that mining is. All the different disciplines of engineering, health, social and -managerial sciences are needed for the good functioning of the mining industry. Although they are all essential, some will play a more important role as a member of the structure. In this discussion it is the role of the most important member, the mining engineer, who is actually responsible for the extraction of the minerals from the earth's crust that must be established. From this we will then be able to analyse his responsibilities and try to suggest the mining engineering program most suitable to prepare this engineer for his future role."

"A GLANCE BACK AT what has happened in the past is often a useful guide to the future, although it should be used mainly to provide a sense of direction rather than a map that must be followed. As a preamble to discussing some of the questions posed by the organizing committee it may be appropriate to briefly review the distribution and careers of the graduates of our Department since the first degree in mining engineering was awarded in 1916. An attempt has been made to keep a record of the locations and careers of the Department's 540 graduates in mining and metallurgical engineering. Almost all of those who graduated before 1930 have now retired, but a very large proportion held positions as senior executives prior to retirement. A major proportion of those who graduated before 1950 are now in what might be considered senior management positions. Those who have 10 to 20 years of experience are generally in work of senior engineering responsibility or in supervisory or junior management ranks, while those who graduated in the last ten years appear to be generally in staff engineering or junior supervisory positions. This classification is admittedly imprecise because it is difficult to determine from a job description whether duties should be considered of an engineering or management nature - a distinction between the two terms is often over-emphasized. Nevertheless, the trend from technical engineering to management responsibilities with seniority and years of experience is clear in the careers that we have been able to follow."
