摘要
以三元煤业4302#回风顺槽工作面为研究对象,分析了工作面的地质情况及力学特性等状况,针对煤矿巷道锚杆安全支护的问题,通过对模型的理论计算得到了巷道锚杆支护的相关参数,同时使用FLAC3D软件模拟了不同排距下预应力场的分布情况,得出了较优的锚杆排距。
The 4302#air return roadway of Sanyuan Coal Industry was taken as the research object,the geological conditions and mechanical characteristics of the working face were analyzed,and the problem of anchor bolt safety support in coal mine roadway was obtained through theoretical calculation of the model.Related parameters of roadway bolt support were got.Simultaneously,the distribution of prestressing field under different row spacing was simulated using FLAC3D software,and a better row spacing of the anchor was obtained.
