摘要
工作面回采过“见方”区域采空区上覆顶板结构改变,稳定性下降,冲击危险性将逐步增强。针对园子沟煤矿1012001工作面“见方”区域冲击地压治理问题,采用微震、应力在线及矿压监测对工作面冲击危险进行监测,根据监测结果设计卸压参数,形成以煤体大直径钻孔卸压和顶板水力压裂为主的综合治理体系,研究成果可为类似条件下冲击地压防治提供参考。
The structure of the overburden roof of the goaf of the stope in the"Square"area of the working face changes,the stability decreases,and the impact risk gradually increases.In view of the garden ditch coal mine 1012001 face"square"regional impact ground pressure control problem,using micro vibration and impact stress and rock pressure monitoring of online risk monitoring,according to the results of monitoring design pressure,the parameter form in the large diameter borehole pressure relief and roof comprehensive control system for hydraulic fracturing is given priority to,research results can provide reference for the similar conditions impact ground pressure control.
