摘要
为了满足华北型煤田岩溶区的下组煤开采对煤矿安全生产、防治水及水害治理的要求,以黄河北矿区邱集煤矿11煤层西一采区综合水文地质勘查为例,结合矿井水文地质条件和开采现状,充分利用矿井现有井下生产和排水系统,研究水文地质勘查方法,突出物探先导,井上下钻探结合,井下放水试验为主,井上下同步观测,同时辅以水化学、环境同位素测试及示踪试验等手段方法,查明水文地质条件,为矿井带压开采下组煤、含水层注浆改造及加固的防治水措施提供依据。
To meet the requirement of safe production, water hazard control and treatment in Northern China type coal field, based on the example of comprehensive hydrogeological exploration for West-I district No. 11 coal seam of Qiuji Coal Mine in North Yellow River mining area, the hydrogeological exploration method was analyzed combining with the hydrogeological conditions and mining situation, with full utilization of the existing underground mine production and drainage system, which emphasized the geophysical prospecting, combination of surface and underground drilling exploration, underground drainage test, synchronization observation of surface and underground, supplemented by water chemistry and environmental isotope tracer test and other methods, so as to obtain the clear hydrogeological conditions, and provide the basis for mine water hazard control measures in the compensated mining of lower coal group and the grouting reinforcement of aquifer.
