摘要
厚煤层大断面巷道由于顶板为煤层其稳定性较低,针对巷道的实际情况,提出采用桁架锚索支护技术支护巷道。首先分析了巷道支护面临的主要难题,其次计算分析了桁架锚索支护的参数不同时的巷道变形情况,确定了巷道的主要支护参数,从而得出了巷道的桁架锚索支护方案。
The stability of large section roadway is weak because of coal roof in thick coal seam. According to this situation, this paper used cable -truss support technology to support this kind of roadways. Firstly, the main difficulties were analyzed, secondly, the displacements of roadway were simulated with different support parameters, and then the main parameter values were maintained.
