    Design methods to control violent pillar failures in room-and-pillar mines

    By R. K. Zipf

    The sudden, violent collapse of large areas of room-and-pillar mines poses a special hazard for miners and mine operators. This type of failure, termed a cascading pillar failure, occurs when one pill

    Geology and geochemistry of Iperindo primary gold deposit, Ilesha schist belt, southwestern Nigeria

    By G. M. Steed, A. O. Oyinloye

    The deposit lies in amphibolite-facies biotite granite-gneisses of Proterozoic age, 4 km east of a major crustal break known as the Ifewara-Zungeru fault. Gold mineralisation is contained in a zone of

    Underground void visualization and volume calculation by a low-cost, laser-based surveying technique

    By K. D. Russ, A. J. Beer

    Non-contact systems for measuring underground voids have used theodolites, reflective or non-reflective laser methods and sonar techniques. An effective but cheaper alternative is based on use of a Wi

    Recovery of molybdenum as molybdic oxide from Rakha molybdenite, India, by soda-ash roasting

    By D. K. Bose, R. H. Rakhasia, V. D. Shah, J. C. Sehra

    A series of experiments was conducted to determine the effects of roasting temperature, soaking period and quantity of soda ash added. At a laboratory scale, under optimum conditions of roasting at 87

    Geopressure zones as proximal sources of hydrothermal fluids in sedimentary basins and the origin of Mississippi Valley-type deposits in shale-rich sequences

    By A. D. Fowler, M. T. Anderson

    A phenomenological model is presented that relates Pb-Zn mineralisation to proximal geopressure zones. Typically, geopressure zones (GPZ) consist of masses of undercompacted sediment encapsulated with

    Laboratory technique for evaluation of methods of suppressing nuisance dust

    By S. P. Godby, S. P. Sharples

    Wind-tunnel tests were carried out of the conditions under which nuisance dust particles (100-1 000 micrometres) become entrained by wind. A laser entrainment monitoring system (LEMS) was used, and wa
