Surrounding Rock Reinforcement Technology of Driving Gateway in Goaf of Integrated Mine
Abstract：According to thegateway driving easy to reveal the goaf problem before the reproduction of the integrated mine, based on the theoretical analysis, numerical simulation and mine strata pressure observation and based on the high failing zone met during the gateway driving and the different conditions of the empty gateway, the bolt, anchor/steel mesh and stone brick lined H type steel shield support multi layers combined support technical means were applied to the reinforced support of the surrounding rock in and along the driving gate- way in the goal, to solve the surrounding rock control technology with poor overburden strata strength in the goaf and poor self loading structure. The practices showed that the reinforced support technology could effectively ensure the surrounding rock stability of the gateway, the convergence of the two sidewalls was 118- 141 mm and the roof and floor convergence was 123- 133 mm.
