Research on Roadway Layout and Surrounding Rock Control Technology under Goaf in Close Range Coal Seams of Hexi Mine
In order to improve the stability of the extremely close coal seam roadway,improve the support effect of the roadway,and solve the stability problems of the surrounding rock of the extremely close single coal seam mining site and the roadway anchor mesh support,this paper focuses on the transportation channel of the 3316 working face of Hexi Mine as the engineering background,uses FLAC 3D numerical simulation software to explore the stress redistribution and plastic zone development of the coal seam excavation roadway,and optimizes the roadway support parameters.The layout of roadway in working faces with similar geological conditions has reference significance.
