摘要
团柏煤矿生产时期陷落柱发育,在全区域带压的下组煤不到6 km2的采掘范围内,揭露陷落柱达107个,其中,导含水的有46个,因此在水源的判别、陷落柱的精准圈定以及综合治理方面取得了丰富的经验。以10-215工作面陷落柱的初步圈定、精准探查以及注浆加固杜绝水害发生为主要阐述内容,介绍推广相关防治水技术经验。
During the production period of Tuanbai Coal Mine,collapse pillars developed.Within the mining area of less than 6 km2 of lower group coal with pressure in the whole area,107 collapse pillars were exposed,of which 46 were water diversion ones.Therefore,rich experience had been gained in water source identification,precise delineation of collapse pillars and com-prehensive treatment.Based on the preliminary delineation,precise exploration and grouting reinforcement of collapse pillars in 10-215 working face,this paper mainly expounded the experience of popularizing relevant water control technology.
