Technology and Technological Optimization of Rapid Driving Support of Coal Roadways
In order to improve the current situation that the roadway driving speed is difficult to meet the working demand of the mining face,the stability of the surrounding rock of the roadway is further strengthened.Through discussing the factors affecting the stability of rapid excavation and support of coal mine roadway,and relying on the actual project,FLAC3D software was used to simulate the construction process,and the optimization scheme of rapid driving support technology was proposed.Finally,three anchor cables with a length of 6 m were adopted to support the right side of the roadway roof,and the circulation spacing was controlled at 2.4 m.The field test proved that the optimized rapid driving support technology had a good control effect on roadway surrounding rock during the driving operation,and the driving speed was increased by 24%.
