矿井规划与煤层气井建设协调发展决策系统

A decision-making system of coordinated development between planning mines and constructing coal-bed methane wells

针对不同矿区煤矿生产特点,结合煤层气吸附/解吸特征,得出3种开采方式和掘进工作面上煤矿安全生产的最高允许含气量模型,并编制了相关程序;应用Comet软件对不同井网下垂直井的产气量进行预测,获取安全临界值下的控制面积、生产年限;通过不同井网直接经济效益和间接经济效益的求算,结合矿井、煤层气井建设特点,最后提出矿井和煤层气井的开发规划方案.实例表明:该系统可较好地协调煤层气与煤矿之间的矿权纷争,达到双赢的目的.

According to the different production characteristics in different coal mines, combined with adsorption/ desorption characteristics of CBM, the models about maximal gas content of mine safety production in three mining models and digging working face were established, at the same time, the related program was designed. By Comet software, the gas production of vertical wells in different wells net was predicted, the controlling area and productive periods in safe critical value were gained. Through different the calculation about direct and indirect economic benefits in different wells patterns, combined with the characteristic of planning mines and construction CBM wells, the development program about mines and CBM wells was put forward. The results show the preferable applied prospect.
