厚煤层拱梁耦合支护参数对围岩稳定性的研究

Study on the Stability of Surrounding Rock by Coupling Support Parameters of Arch Beam in Thick Coal Layer

为了解决厚煤层巷道围岩变形大、稳定性差的问题,利用数值模拟软件对不同支护参数下围岩的应力特征进行分析,给出了锚杆锚索长度及间排距的合理范围,为厚煤层巷道围岩支护参数的选择提供一定的借鉴.

In order to solve the problem of large deformation and poor stability of surrounding rock in thick coal roadway, the stress characteristics of surrounding rock under different supporting parameters are analyzed by numerical simulation software, and the reasonable range of anchor cable length and spacing is given, which provides some reference for the selection of surrounding rock support parameters in thick coal roadway.
