| 摘 要： | 随着煤矿开采深度的不断增加,井下煤矿巷道所受的地应力越来越大,尤其在地质构造活动强烈的地区,井下巷道支护及保持其稳定性更加困难.根据深部软岩条件下煤矿巷道锚杆支护效果不理想的情况,研究高地应力软岩环境下巷道科学的支护方式是保证煤矿采掘深部煤层的关键.矿井支护实践证明高强高预应力变形让压锚杆均压锚杆能够有效的解决深井高地压巷道支护存在的问题.

| Abstract: | The underground tunnel stress increased with the increasing of coal mining depth.And the support and stability of underground tunnel is more difficult in the areas of intense tectonic activity.The scientific support technology in soft rock enviorment with high geostress is the key factor to ensure the deep coal mining under the condition that the tunnel bolt support effect is not ideal in deep soft rock.In practice,mine support proved that the high-strength and high-pretension anchor bolts solved the suppor... |
