摘要/Abstract

摘要： 为研究巷道特厚泥质顶板失稳因素及其敏感性,通过现场调研和理论分析,确定6个影响特厚泥质顶板稳定的主控因素;以黄岩汇煤矿15107工作面为工程背景,采用有限差分软件FLAC5.0开展6因素3水平正交试验,运用方差分析方法研究各影响因素的敏感性;提出针对性的控制措施并开展现场应用。研究结果表明:影响特厚泥质顶板变形的各因素敏感性排序为:直接顶强度＞巷道宽度＞顶板支护强度＞直接顶厚度＞帮部支护强度＞煤层强度;直接顶强度、顶板支护强度及巷道宽度对巷道顶板变形的影响高度显著;煤层强度和帮部支护强度对巷道帮部变形的影响高度显著;提出的强化顶板承载结构及帮顶协同控制的支护对策,现场应用效果较好。

Abstract: In order to study the instability factors and sensitivity of roadways with extra-thick mudstone roof,six instability factors were obtained by carrying out field investigation and theoretical analysis.Panel 15107 in Huangyanhui colliery was taken as engineering background,orthogonal experiments of six factors and three levels were carried out using finite difference software FLAC5.0,and significant instability factors were investigated by using variance analysis.Targeted control measures were put forward and field application was carried out.The results show that the significance sequence of instability factors affecting the deformation of extra-thick mudstone roof is as follows: immediate roof strength,roadway width,roof support strength,immediate roof thickness,rib support strength and coal seam strength,and the immediate roof strength,roof support strength and roadway width have a significant influence on the roof deformation,while the most significant factor affecting the roadway rib stability is coal seam strength and rib support strength.The support principle that intensifies the roof strength,and controls the surroundings rock and the roof together was proposed.The field application effect is good,and there is no supporting structure failure phenomenon.

Key words: extra-thick mudstone roof, orthogonal experiment, sensitivity, numerical simulation, variance analysis
