摘要: 基于余吾矿西翼运输大巷受工作面回采扰动影响变形破坏严重现象,提出了水力压裂顶板和注浆加固的综合控制技术。根据现场地应力和煤岩体原位测试结果,应用UDEC数值模拟软件模拟分析了水力压裂和注浆对巷道围岩变形和应力分布规律的影响,并在现场巷道中进行了工业性试验。研究结果表明:水力压裂和注浆加固综合控制技术能够有效减少巷道受力和控制围岩变形,缩短巷道稳定时间。

Abstract: Based on the influence of the mining disturbance of the working face in the West Wing of a certain mine, the deformation and failure of the working face is affected seriously, and the integrated control technology of the hydraulic fracturing roof and grouting reinforcement is put forward. According to the in-situ stress and the coal and rock mass in situ test results, using UDEC numerical simulation software simulation analysis of the hydraulic fracturing and grouting of roadway surrounding rock deformation and the influence of stress distribution, and industrial test in the field of roadway. The research results show that: the comprehensive control technology of hydraulic fracturing and grouting reinforcement can effectively reduce the stress and deformation of surrounding rock, and shorten the time of roadway stability. The research results provide an important basis for the design of roadway support under similar conditions.
