摘要

针对水体下采煤存在突水安全隐患影响我国煤炭工业健康发展的情况,理论分析了隔水关键层的隔水机理及力学模型,提出了判别隔水关键层的条件和流程,并结合某回采工作面地质钻孔实际揭露情况对隔水关键层的透水性进行了分析。
        Water inrush hazards in coal mining under water body affect the development of coal industry in China.On the theoretical analysis of the mechanism and mechanical model of the water-resisting key strata,the paper proposes the judgment conditions and procedures for the water-resisting key strata.In addition,combining with actual exposure of geological drilling holes in the working face,the water permeability of key strata was studied.
