摘要
针对平山煤矿东翼胶带与东翼轨道联巷的具体地质赋存条件和巷道功能性,选取巷道断面为直墙半圆拱形巷道,净宽4000 mm,净高3600 mm;根据相似巷道支护经验选用锚网索喷联合支护方式,并通过理论计算验算了各项支护参数;最后通过现场工作面实际应用变形量监测,证明此支护方案可以保证东翼胶带与东翼轨道联巷的安全稳定。
In view of the specific geological conditions and roadway functionality of the East Wing belt and the East Wing track combined roadway in Pingshan coal mine,the roadway section is selected as a straight wall semi-circular arch roadway,with a net width of 4000mm and a net height of 3600mm;according to the support experience of similar roadway,the combined support mode of bolt,mesh,cable and shotcrete is selected,and the support parameters are checked through theoretical calculation;finally,the actual application of the field working face is carried out The deformation monitoring shows that the support scheme can ensure the safety and stability.
