摘要
顶板岩层结构中的厚层砂岩顶板是影响冲击矿压发生的主要因素之一,而目前作为煤层冲击倾向鉴定的主要依据是煤层自身的冲击倾向的实验室鉴定结果,这一结果与实际现场有的反差较大。三河尖矿采用主采煤层组合煤岩进行了冲击倾向性试验,为三河尖煤矿高冲击危险区工作面冲击矿压监测及治理提供了基础参数。
Thick sandstone roof in the roof strata construction is one of the main influence factors of rock burst. The main identifying base of the tendency of rock burst is from laboratory result and the result is different from fact widely. Combined coal and rock from main mining coal seam in Sanhejian Colliery is used to test the tendency of rock burst and the results provide basic parameters for the rock burst monitoring and prevention and control in mining face with high tendency of rock burst in Sanhejian Colliery.
