摘要
芦塘煤矿开拓方式为斜井开拓,有2个生产水平,即+600^+510 m水平、+510^+450 m水平。改扩建以后生产水平还有西翼煤层+1 100^+600 m水平。采取物探手段探明落水洞及岩溶裂隙展布并作出富水性评价,查明了矿井水文地质条件,结合矿井开拓方式和生产布局、矿井1#、2#、3#、4#涌水点的存在状况及现有矿井排水方式,确定芦塘煤矿水害防治方案为"以排为主、堵排结合、加强探放冶。
Lutang Coal Mine adopts inclined shaft development, with two production levels, i. e. the level from ＋ 600m to ＋510m and the level from ＋510 to ＋ 450m. After the reconstruction and enlargement of the mine,there is another production level from ＋ 1100m to ＋6OOm for the coal seams in western wring. The position of the sinks and the distribution of the karst fissures were detected by using the geophysical prospecting method, the appraisal of water abundance was made, and the hydrological conditions of the mine were ascertained. Finally, the water disaster control scheme of ＂taking the water drainage as the main process, combining water blocking with drainage, and strengthening water detection and dewatering＂ was decided in Lutang Mine according to the mine development system and production layout,the existence state of No. 1,2,3 and 4 water inrush points and the existing mine water drainage mode.
