摘要
以四台矿西部盘区11#煤层8701综采面为研究对象,首先分析了煤层的地质条件与顶板的情况,并制定出矿压观察的内容与方法,进而对综采工作面顶板、两顺槽巷的端头超前支护单体柱、液压支架进行实时监测分析,根据实测分析总结出该工作面的矿压显现规律。
Taking 8701 fully mechanized mining face of 11 ^# coal seam in Sitai coal mine western panel as research object, this paper firstly analyzes the geology and roof conditions of coal seam, and develops the content and methods of rock pressure observation. The roof of fully mechanized mining face, advance support monomer columns in end of two erossheading roadways and hydraulic supports are real - time monitored and analyzed, and the strata - pressure behavior regularity is summed up according to the actual analysis.
