Coal seam gas is a kind of coal source rocks, and angry by adsorption state of stored in coal bed of unconventional natural gas, is a new type of clean energy and high quality chemical raw materials, is one of important sources of energy in the future. Coal bed gas, the gas is commonly known as "gas" in coal geological history evolution during the formation of gas geological body, its main component is the CH4(methane), calorific value of coal is a generic2-5times. China's traditional mining method is not only coal gas, coal bed gas this invaluable not only caused a serious waste of resources, but also leads to the coal mine gas accident frequency, air emissions increased and security, environmental factors to produce. From the perspective of strategy of national oil safety, coal seam gas than conventional natural gas and oil has strategic sense more, so the strengthening of coalbed gas reservoir study, the self, self storage type of unconventional natural gas expansion research has be imperative.The paper analyzes the Junggar basin in Fukang Coal Mining geological features, coal mine owners, mine geological data revealed by the pioneering works of the Vice air shaft, are discussed in detail the three main elements affecting the methane occurrence:faults and folds, top, backplane lithology and seam depth.The measured gas content of the Fukang coalfield geological survey drilling, downhole measured gas content and seam depth statistical analysis and depth of the relationship, the No.42coal seam gas content and seam depth linear regression, and the establishment of the mathematical relationship model to reflect the relationship of the coal seam depth and seam gas content.The volume method to calculate the Fukang Coal Field within the coalbed methane resources and coal bed methane abundance values, concluded that the Fukang mine coal seam flat area approximately33.47km2coalbed methane reserves15576.26Mm3, the average resource abundance2.28×108m/km2for the middle class, helping improve the economic and social benefits.
