Abstract
Gas geological law in southwest of Shandong province was studied with theoretical foundation and method of gas geology in this paper. It finds that the area in southwest of Shandong province is mostly low gas mining area. But Fucun coal mine of Tengnan mining area, Sanhekou coal mine, Jinyuan coal mine, Tangkou coal mine of Jining mining area and Zhaoguan coal mine of Huanghebei mining area are all gas unusual area. Among them, Fucun coal mine, Sanhekou coal mine and Jinyuan coal mine appear high gas unusual which are mainly affected by magma intrusion, Tangkou and Zhaoguan coal mine form gas unusual area which are mainly affected by thickness of upper bedrock.
