大采深矿井工作面煤层注水防治冲击地压的研究与应用

Research and Application of Water Injection to Prevent and Control Rock Burst in Coal Seam of Large Mining Depth

大采深矿井开采有冲击地压倾向煤层时采用动压注水和静压补水的方法防治冲击地压,通过两种注水方式使煤体塑化,驱替煤层中的气体,从而降低其冲击倾向,减小煤体压力,降低冲击危险。

When mining coal seam with rock burst inclination in large mining depth, dynamic pressure water injection and static pressure water replenishment are used to prevent rock burst. Coal body is plasticized by two water injection methods to displace gas in coal seam, so as to reduce its impact tendency, reduce the pressure of coal body and reduce the impact risk.
