摘要
针对矿井东翼采区上山巷道受采动影响时的维护难题,在现场调研及研究注浆加固机理的基础上,对五条上山巷道设计了针对性的表面喷浆及"浅部—深部"围岩耦合注浆加固方案,并进行了现场工程实践及后续的矿压观测,实现了正常期间尤其是采动影响条件下对巷道围岩的有效控制,实现了安全生产。
Aiming at the maintenance problem of the upper roadway in the east wing mining area affected by mining,on the basis of field investigation and study on the mechanism of grouting reinforcement, a specific surface grouting and "shallow-deep" surrounding rock coupling grouting reinforcement scheme are designed for five upper roadways,and field engineering practice and subsequent mine pressure observation are carried out. The effectiove control of surrounding rock in roodway is realized especially under the influence of mining in normal period, and the safa production is realized.
