Abstract

Hongyuan Coal Mine belongs to low gas permeability coal seam, its permeability coefficient is lower than 0.1m2/(MPa•d), so the gas extraction will be difficult to do and the efficiency of extraction will be low, underground gas extraction has been using polyurethane to seal hole and this method exits a lot of problems. By studying the capsule bag-type high-pressure grouting sealing hole method of system feasibility, and applying it in site successfully, the paper solve problems exit in gas extraction of Hongyuan Coal Mine
