摘要
通过101(首采)综采放顶煤工作面矿压监测,得到了101工作面顶板运动横向矿压规律和顶板运动的纵向矿压规律,据此进行了101工作面直接顶分类和老顶分级,确定直接顶属2类中等稳定顶板,老顶为Ⅱ级。
The pressure observation of 101 （initial mining） Comprehensive Mining Face results in the horizontal mine pressure regularity. and the vertical pressure regularity of the 101 face top roof, based on this, the direct roof of 101 face is categorized and the old roof is classified, the direct roof belongs to the 2nd moderate stable top floor and the old roof is the Ⅱ grade.
