| 摘 要： | 针对西北某煤矿2号巷道支护工程,提出了支护方案,并进行了FLAC数值模拟研究,研究表明,导致该巷道出现顶板下沉量大、底板强烈膨胀、两帮位移大的变形特征的主要原因是巷道埋深大、采空区矿山压力显现显著,进而确定了锚注锚网联合支护作为2号巷道支护方案,监测结果表明,该支护方案合理,效果良好。

| Abstract: | In light of the northwest coal mine No.2 roadway support engineering,the paper puts forward support scheme,and carries out FLAC numerical simulation research.Research shows that deep-lying roadway and distinct mined-out pressure lead to a series of problems,such as large subsidence of the roadway roof,strong expansion of bottom plate,and large two-side displacement.In the end,it determines anchor grouting support as No.2 roadway support scheme.Supervision results show that the support scheme is rational and effective. |
