摘要
该文结合彭庄煤矿1309工作面地质条件,运用综合指数法对冲击地压危险性进行评价,根据地质条件、覆岩运动规律划分了危险区域,采用钻孔卸压、高压注水等方法进行冲击地压预防,取得了较好的效果,为工作面安全、高效生产提供了技术依据。
Combined with the geological conditions of 1309 working face of Peng Zhuang coal mine, evaluated the rockburst hazard using comprehensive index method, according to the geological conditions and the rock movement law of overlying layer divided into dangerous areas, using borehole pressure relief, high pressure water injection method rock burst prevention, obtained better result, and provided the technical basis for work safety, efficient production.
