A new type of pack has been developed primarily for the support of narrow stopes. It was shown in the laboratory that it has characteristics that very closely approximate the optimum required by underground support to achieve hangingwall stability.

The Chemical, Metallurgical and Mining Society, from which The South African Institute of Mining and Metallurgy is descended, had as its coat-of-arms a green shield with a very flat gold chevron dividing the field into two. A crossed pick and shovel occupied the lower half, and an alembic (distilling vessel) and a flaming crucible occupied the top half.

Preliminary tests on cement-consolidated gold-plant slime are outlined, together with preliminary underground tests on the behaviour of two paddocks of the material. Further large-scale testing of the same material pumped to the underground workings from a batching plant on surface is described.

Previous investigations of stress conditions under which core discing occurs have concentrated on shear stress as the cause of this phenomenon. In this paper it is suggested that discing initiates as a result of extension strain, which develops in the field of triaxially compressive stress ahead of the borehole end.

The Johannesburg Branch of The South African Institute of Mining and Metallurgy was officially inaugurated at a General Meeting held in Kelvin House on Monday, 18th January, 1988. In addition to nominating committee members, Mr G. T.G. Emere delivered a presentation on the Barbrook gold-mining project, which is currently in the development phase some 40 km east of Barberton.

A model for the leaching of non-porous particles by B. K. LOVEDAY*, Ph.D. (Fellow) A model has been developed for the prediction of the rate of leaching for an assemblage of non-porous particles in terms of size-distribution parameters. Expressions are developed for batch and continuous operation, and an example of the application of the model is given.

The geostatistical methods given for the estimation of low-ash coal reserves take into account the geological structure of the seam, and consequently give far more reliable results than have been obtained in the past. Confidence limits are given for all the estimates.

The Institute revived a valuable tradition when, on the 19th of March, 1983, it held its first 'annual' banquet in some fifteen years. It was such a sparkling success that it is sure to be held more frequently in future. The success of the occasion was borne out by the fact that the main banqueting hall at the Wanderers Club was filled to capacity, with over four hundred members and guests.

SYNOPSIS A method is described whereby finely ground glassy granulated blastfurnace slag mixed with small quantities of clay, whiting and quartz has been used for making ceramic tiles in the laboratory. The tiles were semi-dry pressed and devitrification as well as sintering occurred during firing. The properties of the resulting product compared favourably in many respects with ordinary ceramic flooring materials.

The metallurgical phenomena in the design and manufacture of high-strength low-alloy (HSLA) steels are reviewed, and some aspects of the production of Supraform TM (thermo-mechanically processed) steel are discussed. . The weldability of Supraform TM is related to changes in the microstructure of its heat-affected zone.
