摘要
以常胜煤矿浅埋深大采高一次采全高综采工作面为背景,通过现场矿压监测,得出了这种条件下工作面的矿压规律,结果表明:工作面中部来压时的平均压力要大于两端头;来压期间支架活柱不但没有下沉,反而会出现一定的增量;85201工作面初次来压步距为75 m,周期来压平均步距23 m,来压期间矿压显现强烈;支架工作阻力总体符合正态分布,能够满足工作面控制工作面顶板的要求。为本矿区其它矿井安全开采提供借鉴。
To winning coal mine deep shallow buried large mining height are broken once mining overall height of fully mechanized working face as the background,through the mine pressure monitoring,it is concluded that this kind of working face under the condition of the mine pressure regularity and the results show that the central face to pressure the average pressure is greater than two end;Instead of a support column during sinking,but there will be a certain increment; 85201 face first pressure step distance is 75 m,23 m,periodic weighting average interval of mine pressure appear during strong; The overall rate of the support working resistance conforms to normal distribution,can satisfy the working face roof control requirements. Serve as a reference for the other mining security.
