Study on Integrated Control Technology of High Ground Stress in Low Gassy Fully Mechanized Working Face

KEYWORD: High ground stress;Dynamic disaster;Gas pre drainage;Deep water injection ABSTRACT: Through analyzing the dynamic disasters of KuZiDong mine 111303 working face in this paper,aiming at the high stress and low gas working face,that ucsing 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.
