摘要 面对薄煤层情况下的采掘接替困难的现象,主张加强机械化成巷技术研究。对此,以石圪台煤矿22上206工作面煤巷掘进与施工为研究对象,首先对连采机在22上煤层的应用可行性进行论证,其次依托数值模拟工具FLAC3D对连续采煤机在煤巷掘进中最佳的空顶距离进行多因素分析,最终对数值模拟所得出的支护设计参数进行实践验证。研究结果表明:22上206工作面采用连采机进行回采巷道掘进更易发挥设备台效,当连续采煤机与锚杆机进行间隔交叉作业时,8 m的煤巷空顶距离更易保证掘进效率。现场实测也表明:在巷道顶板安装5根锚杆和2根锚索的时巷道顶板下沉得到控制(顶板下沉约25 mm)。

Abstract: Faced with the difficulty of excavation and replacement in the case of thin coal seams, this paper advocates the strengthening of mechanized roadway technology research.On this, the author took the investigation and research on the excavation and construction of coal roadway with 22 top 206 working face in Shigetai Coal Mine. First, demonstrate the feasibility of the continuous mining machine's application on the 22 coal seam;Secondly,based on the FLAC3D of numerical simulation,the multi-factor analysis of the optimal empty top distance in the continuous coal mining machine is carried out. Finally, practical verification of the support design parameters derived from numerical simulation. The results of the study finally show that: 22 top 206 working face continuous mining machine for mining tunneling easier to play equipment efficiency, when the continuous shearer and bolting machine spacing operation 8m coal lane empty top distance easier to ensure the efficiency of excavation;Secondly, on-site measurement also shows that the roof subsidence of the roadway is controlled when the roof bolts are installed on the roof of the roadway and the two anchor cables (the ceiling sinks about 25 mm).
