Opttimisation of development layyouts for retreat longwall mining with particular reference to the Australian coal mines
By R D. Lama, A Misra
One of the major factors restricting an increase in the productivity of a longwall mine is lower productivity obtained in a development panel. There has been a significant improvement in gate road dev

Enhancement of dump truck operating efficiency: part 1: method of shovel and truck matching to obtain whole numbers; part 2: optimization of haul-road gradients; part 3: effect of reduced payload
By I. R. Hanby
A simple solution to the problem of whether to round the calculated number of trucks up or down to the nearest whole number is to adopt as criterion the minimum cost per unit volume/mass moved, assumi

Limits of explosibillity of mixtures of coal dust and methane
By P. Golledge, A. D. S. Gillies
An investigation has been carried on samples of three Queensland coal dusts to determine the potential explosibility of dust-gas mixtures. The explosion potential of the samples was classified by the

Effect of ladle additions on chemical composition of metallurgical-grade silicon
By R. M. Cooper, H. K. Herbert, D. N. Phillips
A study was carried out to determine the effects of adding CaCO3, Fe, Al and CaSi2 to the ladle, rather than to the raw materials, in order to increase the concentration of Ca, Fe and Al in the final
