摘要
以大采高作业面矿压显现规律为对象开展探究,结合具体工程实际,借助理论分析和数值模拟等手段,对作业面矿压显现和作业面液压支架受力特征开展针对性分析,并在此基础上对作业面回采作业时的安全性做出分析。研究结果表明A矿2122综放作业面能进行安全的回采作业。
The exploration of the mining pressure appearance law in working face with large mining height was carried out. Com-bined with the actual engineering practice, with theoretical analysis and numerical simulation, this paper carried out the targeted analysis of the mining pressure appearance and the stress characteristics of the working face hydraulic support and on this basis, analyzed the safety of the working face mining operation. The research results show that the mining operations in the 2122 fully mechanized caving face of A Coal Mine can be carried out safely.
