摘要
采用FLAC3D对3种支护方案进行数值模拟计算,确定了锚杆、锚索、注浆加固和反底拱的综合支护方案。从现场巷道位移观测结果看,数值模拟与矿压观测结果基本吻合。
FLAC^3D is used for numerical simulation calculation on 3 support modes and a support plan with bolts, bolting cable, grouting fixing and anti--floor heaving measures is determined for use. Viewing the on--the-site observation of the roadway displacement, the numerical simulation is in compliance with mine pressure data obtained. This shows that the roadway design is rational, the maximum deformation falls within the expected scope and therefore the supports produce optimal results.
