针对霍尔辛赫煤业辅助运输大巷，沿煤层顶底板掘进，巷高大，煤岩体比较破碎，支护难度较大，且服务年限较长等特点，采用高预应力强力锚杆锚索组合支护系统，并采用强力锚索对巷帮进行补强加固。监测结果显示，强力锚杆锚索配合帮锚索能够有效防止高巷帮永久煤层大巷巷帮变形失稳、顶板下沉及底板鼓起现象发生，支护效果良好。
針對霍爾辛赫煤業輔助運輸大巷，沿煤層頂底闆掘進，巷高大，煤巖體比較破碎，支護難度較大，且服務年限較長等特點，採用高預應力彊力錨桿錨索組閤支護繫統，併採用彊力錨索對巷幫進行補彊加固。鑑測結果顯示，彊力錨桿錨索配閤幫錨索能夠有效防止高巷幫永久煤層大巷巷幫變形失穩、頂闆下沉及底闆鼓起現象髮生，支護效果良好。

For auxiliart transportation allets of Hall Shih coal Mine,along the roof and floor of coal seam excavating,lane tall,coal and rock is broken,the supporting is difficult,and the service life of a long wait for a characteristic,USES the combination of prestressed high strength bolt anchor supporting ststem,and USES the powerful anchor cable reinforcement reinforcement on lane to help. Monito-ring results show that the strength of anchor rod anchor wire help anchor can effectivelt prevent the high lane help allets permanent coal lane,roof subsidence and deformation instabilitt backplane summoned the phenomenon occurs,the supporting effect is good.
