This study is on the relationship of the coal seam methane reserve to coal thickness, coal rank, coal seam depth, surrounding rock and geological structure and other factors. The study indicates that different geological factor plays different role in controlling the law of coal seam methane reserve. The coal seam methane rich area, which was formed because of various factors and comprehensive effect, is the coal and methane outburst prone area, and also the key area for coal bed methane recovery. Among all factors, coal seam depth and geological structure is more important factor in affecting coal seam methane content in Pingdingshan mining area.展开更多

So a coal-mining district can be divided into three areas： dangerous area, minatory area, and safe area. This achievement has been successfully applied for regional prediction of coal and gas outburst in Hualnan mining area in China.展开更多

Further, the steps and methods are put forward that coal structure indices applied to forecast coal and gas outbursts.展开更多
