本科论文AbstractThe capture of firedamp in coal mines is an important measure for the prevention offiredamp explosions and firedamp releases.Gas drainage technology refers to the use ofspecial facilities in coal seam,rock and goaf gas extraction technology.Based on the generalsituation of Xingwu mining industry,a complete underground moving extraction system isdesigned and studied,and a complete underground moving extraction system is establishedaccording to the actual situation of Xingwu mining industry and it is of great significance toeffectively solve the problem of gas drainage in the coal mine.Based on the actual gas content of No.4 coal seam in Xingwu Coal Industry.Safetyproduction is the most important management work in mine operation,in which gas contentis an important factor affecting mine safety.Taking active and effective measures to reducegas content is helpful to ensure mine safety production.Therefore,in the production processof high gas mine,analysis of gas drainage method and technological improvement will helpto reduce gas content quantity,to ensure mine safety production.When mining No .4 coal seam,gas emission from mining face is dominated by mininglayer,supplemented by adjacent layer.The occurrence rule of gas in Xingwu Mine is theresult of the combination of geology and geography.This design combined with Xingwu coalcoal seam to give gas source and other characteristics,using the method of borehole drainage.Through analyzing the gas drainage system of Xingwu coal mine,calculating the gasemission and adopting the effective gas drainage method,this paper provides a feasiblescheme for Xingwu coal industry,and also provides a reference for the similar mine gasdrainage design.Keywords:coal mine safety:gas drainage;high gas mine:gas emission
