深部开采动力灾害综合防治技术研究

Study on integrated control technology of high ground stress in low gassy fully mechanized working face

该文通过分析口孜东矿111303工作面动力灾害情况,针对高地应力低瓦斯工作面提出采用"采前瓦斯预抽达标、注水降低煤层冲击倾向性有效"的复合区域措施,证明了"预抽瓦斯+深孔注水"是防治煤岩瓦斯动力灾害最有效的方法。对矿井深部开采动力灾害(主要包括煤与瓦斯突出、冲击地压)治理有参考作用。

Through analyzing the dynamic disasters of Ku Zi Dong mine 111303 working face in this paper,aiming at the high stress and low gas working face,that Using Composite regional measures of ＂the gas pre drainage standard before mining and effectively reducing the coal seam rockburst tendency through water injection＂ was proposed.That proving the ＂ gas pre drainage ＋ deep water injection ＂ is a method of dynamic disaster prevention of coal gas most effectively.There is reference to mine deep mining dynamic disaster（including coal and gas outburst, rock burst） control.
