焦家寨煤矿2号煤综采中位放顶煤工作面矿压研究及应用

通过对焦家寨煤矿2号煤层22105综采中位放顶煤工作面的矿压观测和研究分析,明确了工作面上覆岩层的运动变化规律、变化参数以及矿压显现程度对工作面生产的影响,可为今后工作面两巷超前支护及采煤设备、支架选型提供重要的决策依据。

Study and Application of the Mine Pressure on Working Face of Fully Mechanized Middle Position Coal Roof in No.2 Coal Seam of Jiaojiazhai Coal Mine

Through observation and analytical study on the mine pressure on 22105 working face of fully mechanized middle position coal roof in No.2 coal seam of Jiaojiazhai Coal Mine, this paper makes clear the movement rule and variable parameters of overlying rock strata of working face and the influence of mine pressure＇ s appearing degree on the working face, which can provide important basis for decision-making for the type selection of advance supporting and mining equipment and support of two lanes of the working face.
