Numerical Simulation on Support of Roadway with Compound Roof and Large Cross Section
In order to study the stability of coal roadway surrounding rock with large cross-section and compound roof, three dimensional numerical simulation of optimization of support on big section roadway with FLAC3D was studied under the engineering background of Zhaozhuang Mine of Jincheng Mining Group. Stress distribution and deformation of surrounding rock, stress state of rock-bolt and anchor cable were obtained under different supporting schemes. The affection of the spacing of anchor, the length and spacing of anchor cable to the support in mining roadways were obtained and the optimization of supporting parameters were brought out, which is suitable for joint support of anchor arm and anchor cable of the compels roof on big section roadway.
