Extraction of Pressurized Gas in Low Air-Conductivity Coal Seam Using Drainage Roadway
A drainage roadway was constructed in the fractured zone beside an air-return roadway of a mining site. However, drainage roadways serve only one working face and are discarded after mining, thus weakening sustainable mining practices. To improve the sustainability at mining sites, this paper propos...
