Abstract: According to the geological survey period data of No.1 Mine of Pingdingshan Coal Industry Group,drilling columnar information and gas data in the process of production,we analyze laws of gas geology by using the theory of gas geology.No.1 Mine geological structure is divided into three geological units including the east of two-level, the west of two-level,three-level and the deep;the influence of fold structure,fracture structure, roof lithology and thickness of overlying bedrock on gas occurrence is analyzed,which concludes that the NW and NWW striking faults in No.1 Mine field are conducive to the preservation of the gas,and gas reservoir performance of the NE and NNE striking faults are poorer,the thickness of overlying bedrock is a main control factor of No.1 Mine field gas occurrence.Using the relationship between the thickness of overlying bedrock and gas content,the linear relationship equation between them is introduced,which can be used for the deep gas content prediction;the laws of No.1 Mine tectonic coal distribution are obtained.
