巷道原岩应力测试分析研究

Study on Roadway Original Rock Stress Test Analysis

基于大倾角煤层的赋存及开采条件的复杂性,为了改善矿区大倾角煤层的开采及采区接续情况,对大倾角煤层的覆岩运动及矿压显现规律进行研究。以屯城煤业大倾角煤层综放开采问题为研究背景,利用现场实测的方法,对巷道原岩应力进行测试分析,详细介绍了原岩应力测试方法手段,并对监测结果进行分析,为巷道支护提供依据。

Based on complexity of large dip angle of coal seam occurrence and mining conditions, overburden moving law and mining pressure behavior, in order to improve large dip angle coal seam mining and succession condition of goaf, large dip angle overburden strata movement and mine pressure behavior were studied. large dip angle of coal seam fully mechanized mining of Tuncheng Mining Industry was taken as study background, the original rock stress of roadway was tested by field measurement, the test technology was introduced and the monitoring result was analyzed, which provided reference for roadway support.
