采矿工程采空区巷道掘进支护技术探讨

Discussion on Roadway Excavation and Support Technology of Goaf in Mining Engineering

矿井复采会给采空区带来安全方面的问题,应该结合巷道高冒区、空巷情况,采取综合支护技术对围岩进行加固。结合具体案例,对注浆加固、巷道支护进行设计,并对支护方案的可行性进行探讨,以期为相关工作提供参考。

The second mining of the coal mine will bring safety problems to the goaf.The comprehensive support technology should be adopted to reinforce the surrounding rock in combination with the situation of high caving area and empty roadway.Combined with the specific case,this paper designed grouting reinforcement and roadway support,and discussed the feasibility of the support scheme,in order to provide reference for the related work.
