【摘要】 提出一种围岩稳定性综合分类法，用此法研究平顶山矿区煤巷稳定性变化规律，得到了综合评价围岩稳定性的统计判据，可根据巷道条件及实测信息评价巷道稳定程度，并绘制出多指标围岩分类图。文中相应阐述了煤巷锚杆支护形式选择原则。更多还原

【Abstract】 The overall classification on the rocks stability of coal roadway is derived. Thestatistical criterion for appraising the rocks stability is obtained by studying the coal roadways in Pingdingshan mining area. Based on roadway’s condition and meaured information,the stability degree is evaluated and the multi--index rocks classification figure is drawed.The paper also describes the principle of rocks bolting in coal roadways.更多还原
