Abstract：In order to accurately and quickly predict the coal seam gas occurrence and determine its control factors,the gas occur-rence law of No.10 coal seam in Luling Coal Mine was analyzed by using the sub-source forecast method and fuzzy matter-element evaluation method.The evaluation of control factors of gas occurrence was carried out.The results show that the gas emission of No.10 coal seam is generally high,with the distribution characteristics of high in the central and western regions and low in the southeast.Its gas emission increases with the increase of depth,and the emission range is 9.23-16.11 m3/t.Applying control factor analysis,the study area is classified into three types of regions:the shallow area in southwest is considered as type Ⅰ,and the deep area in northeast is predominantly considered as class Ⅱ and Ⅲ.
