possible dewatering of boreholes situated on the farm properties in the vicinity of an under-ground coal mine. An investigation was required as the land owners complained that there is a reduction in the yield of their boreholes supplying domestic and livestock water to their properties as a result of the underground mining activities. Methods
Underground Mine Design, Planning, and Engineering (US) bringing with them significant experience in the fields of coal hydrogeology and coal mine dewatering. At the Skyline longwall coal mine in Utah, the two teamed up to determine the source of large, persistent groundwater inflows emanating from fracture intersections.
Keywords— Underground mine, dewatering, and pumping network I. hazard zones and quantity flow rates, location of dams and INTRODUCTION Mining of minerals involves excavation below the earth surface. The deep seated mineral that lies below the water table requires pumping activity for carrying out mining operations.
eo Dewatering-Systems in the Kreka Coal Basin This paper is giving a brief description of dewatering system in underground mines and, separately, in open pits. · In the Kreka syncline, where underground mining is being done, dewatering of water-bearing sand is being done by one-line system of drilled vertical wells and inspiring
Future underground coal mines will require dewatering when they penetrate the Blackhawk-Star Point aquifer. A finite- difference, three-dimensional computer model was used to estimate the inflow of water to various lengths and widths of a hypothetical dewatered mine and to estimate drawdowns of
