山西某矿现开采15号煤层一采区,位于井田西北部。为更好地利用矿井现有的排水系统,结合地质、水文地质成果及预测的15号煤层矿井涌水量,同时根据一采区井下涌水点的涌水量观测结果,从大气降水、地表水、含水层水、采空区积水、奥灰水和构造等方面分析对矿井充水的影响,具体到大气降水及地表水体、含水层水、本井田采空区积水、周边矿井和构造等对一采区矿井充水的影响,充分掌握15号煤层一采区水文地质特性,从而预测当生产能力达到6.0×105t/a时,15号煤层一采区矿井涌水量的大小。
A coal mine in Shanxi Province is now mining a coal mining area on the 15th and is located in the northwest of the minefield. In order to make better use of the existing drainage system in the mine, combined with the geological and hydrogeological achievements and the prediction of the water inflow from No.15 coal mine, at the same time, according to the observation results of water inflow at the underground water level in a mining area, Stratified water, gob reservoir water, and Ordovician gray water and tectonics to the water filling in mines. The detailed analysis is made on the effects of atmospheric precipitation and surface water bodies, aquifer water, gob reservoir in the mine field, surrounding mines and structures A mining area filled with water to fully grasp the 15th coal seam a hydrogeological characteristics, to predict when the production capacity reached 6.0 × 105t / a, No. 15 coal mine a mining area the amount of water in the mine.
