【摘要】 为了防止工作面瓦斯异常涌出引起的瓦斯事故的发生,采用"瓦斯地质分析方法+GIS空间分析技术",在实现了对煤矿瓦斯地质的动态分析的基础上,结合工作面高(低)负压瓦斯抽采动态信息,采用分源预测的方法实现了对工作面前方煤体瓦斯涌出量动态预测;在对系统架构设计的基础上,运用MapGIS关键技术实现了软件功能并在林华煤矿得到了成功运用。更多还原

【Abstract】 In order to prevent the occurrence of gas accidents caused by abnormal gas emission at the working face of coal mine,we adopt the methods of gas geological analysis and GIS spatial analysis technology to implement the dynamic analysis of coal mine gas geology. And on this basis,by using prediction method of different- source and combining dynamic information of gas extraction at working face to dynamically predict the amount of gas emission. Ultimately,based on system architecture design,we use MapGIS key technologies to realize the function of software and get a successful application in Linhua Coal Mine.更多还原
