围岩失稳巷道综合加固技术研究

Study on comprehensive reinforcement technique of surrounding rock instability roadway

本文以晋煤集团亿欣煤业盘区变电所巷道为研究对象,该巷道在使用过程中出现两帮破碎、底鼓严重,变形量大等现象,严重影响该巷道的使用,实践证明,传统的锚网索加强加固措施不能有效控制巷道变形,采用对巷道围岩变形区域按照底板加固、顶帮连体支护、顶板二次注浆的方法依次进行治理,取得了良好治理效果。

in this paper the jin coal group hin a panel of coal roadway as the research object, the substation in the roadway in the process of using the two broken, severe floor heave, such as large deformation phenomenon, the serious influence the use of the roadway, practice has proved that traditional anchor wire rope strengthening reinforcement measures cannot effectively control the deformation of roadway, the area of roadway surrounding rock deformation in accordance with the slab reinforcement, top help conjoined supporting and top secondary grouting method in management, has obtained the good management effect.
