摘　　要：为解决金能煤业穿层巷道围岩大变形现象,采用数值模拟和现场试验的方法,模拟分析了不同工况条件下试验巷道围岩变形规律,巷道在穿层过程中围岩变形将显著增加。基于此,提出在东翼集中回风上山穿层范围采用分区域锚注喷联合控制技术。技术应用后,实现了东翼集中回风上山的稳定控制。In order to solve the problem of large deformation phenomenon of the cross layers roadway surrounding rock of Jinneng Coal Industry,numerical simulation and on-site testing methods are used to simulate and analyze the deformation law of the test roadway surrounding rock under different working conditions.During the process of roadway crossing layers,the deformation of the surrounding rock will significantly increase.Based on this,it is proposed to use a regional anchor grouting and spray joint control technology in the range of centralized return air uphill and crossing layers in the east wing.After the application of the technology,stable control of centralized return air uphill in the east wing is achieved.
