Open publisher page 0 citations

Abstract

Aiming at the features of outburst mines in Jincheng Mining area, outburst prevention principles are concluded. On the designing cases of the outburst mines, the regional outburst prevention measures are optimized. The results show that the pre-drainage of coal-bed methane is reasonable. Besides, regional and local outburst prevention measures are presented. Reducing the times of uncovering coal seam is also proposed. The prevention measure could effectively control the coal and gas outburst, which is important for Jincheng Mining Area.
