深部岩巷围岩变形规律及其控制技术研究

The Research of Deep Rock Roadway Deformation Analysis and Control Technology

针对鹤煤十矿在深部开采过程中存在巷道围岩变形问题,通过现场调研、围岩物理力学性质实验、围岩松动圈测定和巷道施工围岩变形监控,研究了围岩的变形规律,并在高地应力、大埋深和围岩变形比较严重的12采区运输机上山巷道中,提出了以锚注结合增强型U型钢的巷道围岩变形控制技术。

In view of the surrounding rock of roadway deformation problems revealed in the process of deep mining in the 10th mine of Hebi Coal Industry Corporation, through the site investigation, the surrounding rock experiment of physical and mechanical properties and the measurement of broken rock zone of surrounding rock and deformation monitoring of surrounding rock of roadway, we studied the deformation law of surrounding rock. And in the 12 mining area transport roadway of high ground stress, large buried depth and serious surrounding rock deformation, we proposed the deformation control technology of surrounding rock of roadway which combines Holt-grouting with enhanced U-shaped steel.
