近距离下伏煤层回采巷道支护研究

Research on Support of Mining Roadway in Underlying Coal Seams

为保证近距离煤层下伏煤层回采巷道在生产服务期间的安全性要求,实测研究了3下煤层的围岩裂隙发育特征,提出了3下1007运输巷高强度锚杆支护技术方案,并通过FLAC3D数值计算软件模拟研究了该方案在此类条件下的可行性和支护效果,该研究可以为同类条件下的巷道支护方案选择提供依据。

In order to ensure the safety requirements of the mining roadway under the coal seam in the near distance during the production service, the development characteristics of the surrounding rock fissures in the 3 coal seams were measured and researched, and the high-strength anchor support technology scheme for the 1007 transport roadway in 3 coal seams was proposed, FLAC3 Dnumerical calculation software simulates the feasibility and support effect of the scheme under such conditions.The research can provide a basis for the choice of roadway support schemes under similar conditions.
