Abstract
To investigate the mine pressure behavior laws of mining roadways in coal seams at different horizons,this study takes the ZF1409 working face of Yadian Coal Mine as the engineering background.Using FLAC3D numerical simulation software,numerical simulations were conducted for two scenarios:the mining roadway of the ZF1409 working face being excavated in the coal seam and in the siltstone horizon.Simulations were performed at four stages:before mining,after 100 m of mining,after 200 m of mining,and after 280 m of mining.The stress concentration and deformation of the surrounding rock under different schemes were simulated,calculated,and analyzed to reveal the mine pressure behavior laws of the roadway under the coupling effect of rock layer characteristics and mining disturbance.The results show that when the mining roadway of the ZF1409 working face is excavated in siltstone,the stress on the roadway is significantly reduced,and roadway deformation is effectively controlled.Affected by the mining activity of the adjacent ZF1407 working face,the pressure and deformation of the return airway in the ZF1409 working face are greater than those of the belt gateway.The research findings validate the"rock medium-stress field"coupling control theory,providing a scientific basis for optimizing roadway excavation horizons in deep,high-stress conditions and for preventing and controlling rock bursts.关键词
