Abstract
Using the experimental platform of gas flow field in goaf, a similar simulation study is carried out to study the influence of coal seam inclination angle on gas flow field distribution in goaf and the law of gas distribution variation in goaf. The gas seepage law in goaf is simulated when the inclination angle of coal seam is 13° or 37° or 68° respectively. The distribution law of gas flow field in goaf under three inclination angles is compared and analyzed, and the specific position of spontaneous combustion in goaf is further determined, which is the mining of coal seam with different inclination angle. It can be used for reference in preventing gas explosion in goaf and preventing spontaneous combustion of coal left in goaf.
Yang Yongchen (1960), Professor of Lingshou, Hebei Province and tutor of Master’s degree, mainly engaged in coal mining and safety research.
