综采面顺槽锚杆支护技术研究

Research on Bolt Support Technology for Fully Mechanized Face

通过对巷道变形中锚杆支护设计理论的分析研究,选取新景矿3煤层顺槽锚杆(索)支护为研究对象,并结合锚杆设计支护参数作为理论依据,运用FLAC3D软件对3煤层进行数值模拟,通过对比分析图像中巷道支护前后围岩位移的变化情况,进而对锚杆的支护方式及参数进行确定,最终选取最优支护方案。

Based on the deformation of roadway in bolt supporting design theory analysis, selection of Xinjing coal mine three coal seam roadway bolt （cable） support as the research object, and combined with the design of bolt supporting parameters as the theoretical basis, using FLAC3D software to simulate the No. 3 coal seam, through the comparative analysis of the image of roadway change of support and surrounding rock displacement, and the bolt support method and parameters were determined, the final selection of the optimal supporting scheme.
