当前形势下,煤矿开采得到推进,煤矿开采的深度也越来越深,对深部软岩条件实施支护的要求越来越严格。传统的方法和经验已经不能满足现有的要求,一味地运用原有方法和经验,很可能会对深部煤矿巷道稳定性产生影响,甚至会降低其稳定性。有些施工人员主张将锚杆长度增加,但是,即便这样做仍然不能对支护效果进行保证。所以,要在原有支护经验的基础之上,具有针对性地运用高强锚杆,进而对深部煤矿巷道安全提供保障。
Under the current situation, coal mining has been pushed forward and the depth of coal mining has become deeper and deeper. Requirements for supporting deep soft rock conditions have become more and more stringent. The traditional methods and experiences can not meet the existing requirements. Using the original methods and experience blindly will probably affect the stability of the deep mine roadway and may even reduce its stability. Some builders have argued for an increase in the length of the bolt, but even if this is done, the support effect can not be guaranteed. Therefore, on the basis of the original support experience, we should use the high-strength anchor rod in a targeted manner to provide guarantee for the roadway safety in deep coal mines.
