摘要

针对大兴煤矿3 208材料巷顶板岩石特征和煤层赋存条件，结合现代煤巷支护技术理论，提出了该巷道锚杆锚索挂网支护参数，并对其顶板离层、巷道收敛变形、锚杆（索）锚固力等日常巷道矿压与支护合理性进行了长期的监测。试用和监测结果表明，大兴煤矿较软弱顶板煤巷应用锚索带网支护技术是成功的、可行的。此外还对层理、节理和裂隙发育的破碎厚伪顶软弱围岩巷道的支护方式提出了建议。

Abstract

According to the rock characteristic and coal seam occurrence condition of 3208 material tunnel roof at Daxing Coal Mine

combining with modern theory of coal tunnel support technology

the combined support parameters of bolt

anchor cable

steel strap and mesh for the tunnel

are put forward; and daily tunnel pressure and support observation

such as roof separation

tunnel convergence deformation

anchorage stress of bolt (anchor cable) etc. have been done at a long time. The results of try-on and observation indicate that the application of bolt

anchor cable

steel strap and mesh combined support technique at Daxing Cola Mine soft-roof tunnel is successful and feasible. Suggestions about the support way of tunnel in samdwich and joint and cracked fake top are also presented.
