Abstract
- Using the theory of gas geology, at No. 8 Mine in Pingdingshan mine area, based on the control characteristics of geological structure on the regional area, mining area and mine gas occurrence, authors studied the control characteristics of a three-level structure on outbursts coal seam gas occurrence characteristics in Pingdingshan No. 8 Mine. Research results show that the regional structure establishes the fundamental key of high gas in Pingdingshan mine area. The mining area is divided into two gas occurrence units by geological structure, and the gas occurrence is axially symmetric distributed around Likou syncline. The structure controls the outbursts coal seam gas occurrence and the distribution of structural coal in the coalfield, which causes the banding distribution of coal seam with coal and gas outbursts hazard. Based on the study, the coal and gas outburst favorable zone is reasonably divided. [ABSTRACT FROM AUTHOR]
