摘　　要：瓦斯(煤层气)突出是指煤矿生产过程中,从煤层、岩层及采空区放出的各种有害气体在工作面上富集并涌出,从而引起瓦斯爆炸的煤矿灾害.因此,查明煤层瓦斯富集区域,对可能瓦斯突出点进行预报和应用,是当前煤矿生产中亟待解决的重要课题.本文应用地理信息系统基本原理,结合煤层气地质学、构造地质学等学科的理论和方法,对游离态的煤层气进行深入研究.在此基础上借助ArcGIS平台,根据游离态的煤层气的生、储、盖条件建立了分析模型及空间分析数据库;应用于王营井田,在此基础上预测了王营矿区游离态的煤层气的可能聚集带,为今后的煤层气勘探指明了方向.Coal-bed methane （CBM） is produced in coal mining. From coal, rock and goal release of harmful gases in the working face and turned enrichment, which led to a gas explosion in a coal mine disaster. Consequently, the identification of coal-bed methane concentration regions, highlights the potential for forecasting gas and application of the current coal production. Based on the fundamental of geographical information system, combing with theories and methods of coal-bed methane geology, structural geology, we make a deep study on coal-bed methane of dissociated in virtue of ArcGIS platform. Based on generation reservoir overburden condition of admixture gas in this district, we establish an analysis model and spatial analysis database,and apply them to the Wangying coalfield. Then we perform a forecast of possible gather area about coal-bed methane of dissociating in the Wangying coalfield, pointing direction of coal-bed methane exploration in the future.
