摘要
基于锚杆支护机理研究,利用FLAC3D数值模拟手段对淮南某矿未稳定采动影响大断面回采巷道断面形式进行了选择分析,确定采用直墙半圆拱形断面,并对该回采巷道进行了支护参数设计。
Based on the mechanism study of anchor and cable combining support, a section-shape selection analysis by FLAC3 Dnumerical simulation is set up and the semicircle straight wall section is adopted finally, further, the parameters design is made for the roadway.
