中文摘要：
复杂破碎围岩状态下大断面巷道开挖后，巷道围岩出现应力集中。受开采扰动的影响，岩体强度大大降低，围岩呈现不稳定变形破坏，如冒顶、片帮等，给煤矿安全生产带来极大威胁。依据我国西部强震区复杂围岩环境下某煤矿大断面巷道顶板离层、巷帮压力等监测数据，结合钻孔窥视，围岩松动圈监测系统，对该区顶板离层、巷帮压力变化规律进行了声-光-电多元指标参数综合研究，较全面的对复杂破碎围岩状态下大断面巷道的稳定性进行综合分析。
英文摘要：
After large section entries excavated under complex fragmentized surroundings, stress in adjacent rock may concentrate which makes the rock＇s strength decrease seriously. Based on field monitoring data of roof delaminating and pressure in large roadway of a coal mine at the western intensity earthquake region surrounded by complex geologic condition, associated with borehole camera tool and Broken-Zone Device, the law of roof＇s delaminating and pressure development are researched using multiparameters. Large section entry＇s stabilization under complex fragmentized surroundings are estimated and evaluated comprehensively.
