为解决深部区域支护难题,采用优化设计、地应力测试、高强支护技术,简化了生产系统,摸清了地应力情况,试验了多种高强支护技术方案,解决了深部巷道支护困难等问题。通过优化设计布置大断面巷道,针对高地应力、软岩等地质条件,可以采用锚网索喷+注浆锚杆+注浆组合锚索作为深部巷道的支护方案,实现巷道的合理布置和支护安全。
In order to solve the problem of supporting in the deep area, the optimized design, in-situ stress test and high-strength support technology were adopted to simplify the production system, find out the situation of in-situ stress, tested a variety of high-strength support technology programs and solved the difficulties of deep roadway support And other issues. Through the optimal design and layout of large cross-section roadway, for high ground stress, soft rock and other geological conditions, you can use anchor net spray + grouting anchor + grouting anchor cable as the support of deep roadway to achieve the reasonable layout and support Protect safety.
