摘要
以山西沈家峁煤矿10101工作面为背景,通过理论分析和现场实际,系统分析了10101综放工作面瓦斯涌出来源、流动特性及其影响因素,对综放工作面"U+L"型通风瓦斯运移规律进行研究。研究结果表明:在综采放顶工作面采用"U+L"型通风方式,取得了显著的效果,解决了综放工作面上隅角和回风流瓦斯超限问题,保证高产高效工作面效能的发挥,取得了可观的经济效益和社会安全效益。
Based on Shanxi Shenjiamao coal mine 10101 working face as the background,through theoretical analysis and field practice,the system analyzed 10101 fully-mechanized working face,flow characteristics and influencing factors of gas emission source,"U+L"type ventilation to fully-mechanized sublevel caving mining working face gas migration rule were studied.The results show that in the fully mechanized caving coal face adopts"U+L"type ventilation method,has obtained the remarkable result,solved the corner at the fully-mechanized coal mining face and return roadway.the problem,to ensure high yield and high working efficiency,has achieved considerable economic benefits and social security benefits.
