摘要
针对潞安矿区大平矿锚杆支护巷道现状,通过巷道表面位移、锚杆(索)受力、顶板离层等矿压观测及数据分析,研究锚杆(索)受力及巷道围岩变形规律,从而评价巷道支护现状,判断巷道的稳定性及支护结构的合理性。
According to the current application situation of bolt-supported roadways in Daping Coal Mine of Lu＇an Mine, this paper researched the anchor rod（rope） stress and the deformation law of surrounding rock of roadway through the surface displacement of roadway, the anchor rod（rope） stress, roof separation and so on, mine pressure observation and data analysis so as to evaluate the current situation of roadway support, to determine the stability of the roadway and the rationality of supporting structure.
