第四系沙砾含水层及采空区积水是梅河矿区急倾斜特厚煤层残采区综放安全复采的主要威胁，也是亟待解决的重要问题。以三井5109区为研究区域，在对采空区积水瞬变电磁探测和对急倾斜特厚煤层水平分层覆岩破坏高度预计的基础上，对F4断层留设了足够的隔水煤柱，并针对岩层移动规律，求算出工作面采动影响波及到的采空区积水区的范围，评价结果认为：在回采前要确保采空区积水降至+172 m标高以下方能保证安全开采。

Quaternary gravel aquifer and the goaf water are the main threat of safety mining of steeply inclined thick coal seam with fully mechanized top coal caving mining in Meihe mining area. It is an important problem to be solved. Taking Mitsui 5109 zone as the research area,based on the transient electromagnetic sounding and the goaf water of and the failure height pre-diction on horizontal overburden of the steeply inclined thick coal seam,abundant coal pillars for the water barrier at F4 fault are set. In the light of the strata movement law,it is calculated that the mining influence in working face spread to the goaf water are-a. The evaluation shows that:before mining,the elevation of goaf water just declined to +172 m can ensure the safety mining.
