摘　　要：针对山西晋城西北矿区突水隐患现状,就其生产过程中采动破坏对底板隔水层内部构造的影响问题作了研究。选取不同煤层下的底板岩体样本模型,分别采用二维F-RFPA和COMSOL数值模拟方法,对比正常隔水层和有构造发育隔水层的采动破坏规律。模拟结果表明,不同煤层的水文地质物理特征变化差异较大,底板含陷落柱等构造的隔水层更易出现突水隐患。Aiming at solving the hidden danger of water inrush in northwest mining area of Jincheng,Shanxi Province,this paper studies the influence of mining failure on the internal structure of floor aquifer during production.Sample models of the rock mass of the floor in different coal seams are selected and two-dimensional F-RFPA and COMSOL numerical simulation methods are used to compare mining failure rules between normal aquifer and aquifer with structure.The simulation results show that the hydrogeological and physical characteristics of different coal seams vary greatly,and the water-inrush hazard is more likely to occur in aquifers with structures such as collapsed columns on the floor.
