    Thermodynamics of CaF2-based melts containing MnO

    By M. W. Davies, P. N. Smith

    The activity of MnO has been measured in the system CaF2-MnO at 1773 and 1873 K and in the system CaF2-CaO-MnO at 1773 K by the method of equilibration with platinum. Large positive deviations from id

    The connexion between the north-western European coalfields.

    By Stainier X.

    The connexion between the Kent and the Continental coalfields on the one hand and the western British coalfields on the other has been for many years a controversial subject between geologists. These

    The Prevention of Spontaneous Combustion in the North Nottinghamshire Area

    By R. B. Scott, J. Hewitson

    The paper investigates the historical information relating to spontaneous heatings which have occurred within the area from 1955 to date. From this information the seams most liable are identified and

    Preliminary modelling of groundwater inflows at Gays River mine, Nova Scotia, Canada

    By R. Macleod, G. G. Bursey, T. R. C. Aston, J. E. Gale

    In 1991 the problems of water inflow at the mine were addressed by a three-phase study. A three-dimensional finite-element computer code, CFEST (Coupled Fluid, Energy and Solute Transport), was used t

    Underground Heatings at Lynemouth Colliery

    By M. Riddell

    This paper describes the incipient heatings that occurred below ground in the High Main and Main seams at the mine between the years 1963 and 1966. The possible causes, effects and activities associat

    Power draw of wet tumbling mills and its relationship to charge dynamics, part 1: a continuum approach to mathematical modelling of mill power draw; part 2: an empirical appriach to modelling of mill power draw

    The first part describes a model (the C model) based on the motion of the grinding charge. The charge is treated as a continuum, which allows analytical solutions to the equations that are developed.
