深部高应力软岩巷道让抗耦合控制技术
Yield-resistance Coupling Control Technology for Roadway in Deep High Stress Soft Rock
摘要
Abstract
Surrounding rock of deep mine engineering and stope have the characteristics of soft rock, such as large deformation, high pressure and difficult to support. Taking the main haulage roadway of Zhaogu Coal Mine as engineering background, combined with the project status of complex chamber structure, large ground pressure stress, and large surrounding rock deformation, failure characteristics and mechanism of surrounding rock were discussed according to the methods of borehole imaging, radar detection, and laboratory test. Based on the coupling support ideas of "bolt-grouting first and rigid closed last", a joint control technology of roadway construction was formulated, and the control effect of two kinds of schemes was studied. The results show that the coupling control scheme can make coordinate deformation of surrounding rock and supporting system, and improve the stress state of surrounding rock and supporting structure, achieve the objective of stability of roadway.关键词
