Abstract: Based on the research on gas geological characteristics of 17 pairs of outburst mines, we analyzed the measured data of gas content, pressure and emission quantity, summarized the rules of gas geology in Pingdingshan mining area. It has clarified the control of the regional tectonic evolution, the structures in mining area and the structures in mine for the gas occurrence in Pingdingshan mining area by using structural level-control theory, and put forward the gas occurrence features under stepwise tectonic control. Meanwhile, the high gas setting of gas occurrence is established by the regional tectonic evolution, while the gas occurrence regularity of high content in the east and low content in the west and symmetrical distribution in Pingdingshan mining area is controlled by Likou syncline. Moreover, the gas distribution is different in different zones and different coal seams in a mine, and the gas occurrence is controlled by the structures in the mine area. The result has provided theoretic guidance for gas occurrence distribution forecast and coal and gas outburst control.
