新兴矿薄煤层注水防治冲击地压技术实践

针对新兴矿薄煤层在深部开采阶段频繁出现的冲击地压,通过对冲击地压发生机理的综述,在此基础上研究煤层注水防治冲击地压的原理,结合新兴矿41601工作面冲击地压实际情况,通过对煤样的吸水率测试综合评判得到采取煤层注水软化煤体,降低发生冲击危险的可能性和合理性。提出了应用煤层注水防治薄煤层冲击地压,并取得了显著效果,对薄硬煤层冲击地压防治有重要的指导意义。

The Technology Practice of Using Water Injection to Prevent and Control the Rock Burst in Emerging Mining Thin Coal Seam

In view of the frequent percussive ground pressure in the stage of deep mining in emerging mining thin coal seam, through the summary of the occurred mechanism of rock bursts, on the basis of this, the paper studies the principle of coal seam water injection prevehtion and control of percussive ground pressure, in combination with the practical situation of coal mine 41601 face impact ground pressure, through the coal sample water absorption test comprehensive evaluation to get coal seam water injection soften coal, it reduced the possibility of danger and rationality, puts forward using the coal seam water injection to prevent and control rock bursts, which has made significant effect, and has important guiding significance.
