摘要
平煤十三矿己四采区大巷受深部高应力及采矿扰动等的影响,出现了巷道支护困难、围岩强流变等工程动力响应。为有效解决此类问题,采用数值模拟、室内试验、现场监测相结合的手段,成功对己四服务大巷进行了锚注支护技术工程实践。研究结果表明,锚注支护可有效提高抵御围岩承载及变形的能力,对围岩控制效果较为理想,具有较好的推广应用价值。
Difficult roadway support and surrounding rock strong rheological engineering dynamic response appear by the influence of high stress and mining disturbance in the fourth mining area road way of No.13 coal mine. In order to solve such problems effectively, using the numerical simulation,laboratory test and field monitoring to achieve the engineering practice of bolt-grouting support. The research results show that bolt-grouting support can effectively improve the ability to resist the bearing and deformation, and obtain good technique and economic benefits.
