摘　　要：煤矿在开采过程中,顶底板事故是威胁煤矿安全生产的主要因素,以里必煤矿为研究对象,对钻探数据和岩石物理力学实验结果进行统计,对煤矿主采煤层顶底板工程地质特征进行分析,用岩体质量系岩体质量系数法和岩体质量指标法对煤层顶底板岩体质量进行评价,对顶底板的稳定性进行分析,结合煤矿的构造发育特征对顶底板事故进行预测,为煤矿安全开采提供理论依据。In the process of mining,the top and bottom slab accident is the main factor threatening the safety production of mines,Libi Mine was taken as the research object,the drilling data and rock physics and mechanics experimental results were counted,the engineering geological characteristics of the top and bottom slab of the main mining coal seam were analyzed,the rock quality coefficient method and the rock quality index method of the rock quality system were used to evaluate the rock quality of the top and bottom slab of the coal seam,and the stability of the top and bottom slab was analyzed.The analysis of the stability of the top and bottom slabs,the prediction of top and bottom slab accidents in combination with the tectonic development characteristics of coal mines,provided a theoretical basis for safe coal mining.
