Abstract: In order to accurately understand the gas content distribution of the seams in the mine,to effectively control gas disaster and to develop and utilize the gas r esources,the paper analyzed the gas contents of 92 coalbed methane wells drilled in Sihe Mine ,Zhaozhuang Minefield and the neighboring regions. During the geological e xploration period, there were 86 gas contents measured there were in-situ gas contents measured in the underground mine during the mine production period. The results s howed that when the seam depth in Sihe Mine was about 300 ~ 450 m,the coalbed methane content was about 1.28 ~ 1.37 times higher than the site measured gas conten t in the underground mine and the gas content during the geological exploration period was about 1. 01 ~ 1. 10 times higher than the gas content measured in the undergro und mine.When the seam depth in Zhaozhuang Mine was about 600 ~ 750 m,the coalbed methane content was about 1.05 ~ 1.41 times higher than the site gas content me asured in the underground mine.When the seam depth was about 450 ~ 700 m,the geological gas content was about 1.01 ~ 1.35 times higher than the site measured gas C ontent in the underground mine.Based on the circumstances,the main causes to make differences of the multi-source gas content data would be the different parameter me asuring and testing condition,ifferent sampling method,residual gas content measuring method and different contents.
