摘要
针对告成矿13221工作面回采期间对其下方大巷造成破坏的难题,根据理论分析、现场实测方法,依据不同地质条件,不同支护方式制定差异化加固技术方案。13221工作面回采期间及回采过后大巷矿压观测结果表明,该加固方案能够满足巷道后期安全生产需求。
Aiming at the problem of the main roadway damage below13221 working face of Gaocheng Coal Mine during mining, using the theoretical analysis, and the field measurement method, according to different geological conditions, different supporting methods, the differential reinforcement technology scheme were developed, during 13221 the working face mining and after mining over the roadway ,the pressure observation results show that the reinforcement scheme can meet the needs of safety production in the later stage of roadway.
