Application of Comprehensive Gas Control Technology for Working Face of High-gas Coal Seam

In order to optimize the layout of working face,improve the recovery rate and alleviate the
tension of mining and excavation,the layout of working face changed from U + L type to simple single U
type. According to the occurrence of coal seam and the characteristics of gas emission,on the basis of rea⁃
sonable ventilation system and sufficient air distribution,comprehensive gas control measures are also ad⁃
opted. The excavation adopts the technical measures of excavation and drainage + release drilling,and the
mining adopts the technical measures of unilateral bedding directional coal seam drilling + roof tendency di⁃
rectional drilling + upper corner buried pipe gas extraction. Through above gas control technology,the gas
problem in the mining process of single U ventilation working face in high gas coal seam is effectively
solved,and the economic and social benefits are remarkable.
