摘要
探讨了大倾角半煤岩巷道采用锚杆支护的可行性,分析了留设上顶角煤对巷道围岩应力分布和维护状况的影响,提出了这类巷道的锚杆支护方案,并介绍了应用于工程实践的成功经验。
Study the feasibility of the bolt support technology used in deep dip angle half-coal rock roadway in this paper, and analysis the effect on roadway＇s rock stress distribution and condition of maintenance when the vertex angle coal hold, finally, a bolting support design is suggested, and the research results have been applied to the project successfully.
