摘要: 针对亭南煤矿深埋大采高综采工作面冒顶、煤壁片帮事故频发问题,对该矿205工作面、回采巷道矿压分布规律和工作面煤壁片帮、冒顶情况和回采巷道支护效果进行了系统的观测。观测结果表明:205深埋大采高工作面矿压显现剧烈,且冒顶片帮集中发生在工作面中部位置;回采巷道超前支承压力和超前支承压力影响范围较大,回采巷道收敛变形大,且有冒顶片帮发生;工作面周期来压时工作面与回采巷道有明显的来压现象。根据观测结果分析,提出控制工作面冒顶片帮的建议,并给出了回采巷道的支护方案。

Abstract: Abstract: TinNan coalmine in order to control the roof caving and coal Wall caving of frequent accidents at the large mining depth and high cutting height fully mechanized mining face, We are Systematic furnished the strata pressure behavior law of Face and entry and the case of roof caving and coal Wall caving, and the effect of entry support. Data by analyzing the strata pressure behavior law and its distribution characteristics for roof, and analysis the adaptation of support, gives cave basic prevention measures to help the accident. Observations suggest that an intense strata pressure behavior at 205 large mining depth and high cutting height mining face, large deformation large convergence in the mining gateway and large sphere of influence of the lead abutment pressure. it provide a theoretical basis For mine safety and efficient production and a reference for other coalmine in the same mining area.

Key words: large mining depth and high cutting height, strata pressure behavior law, crossheading convergence deformation, roof caving and coal Wall caving, abutment pressure
