摘要
瓦斯抽采钻孔参数的改进和优化是提高瓦斯抽放效率、进行瓦斯防治比较重要的一个环节。本文以贵州省水城矿区某煤矿为例,对钻孔直径、抽放负压两个钻孔抽采参数,采用FLUENT数值模拟软件进行了优化研究。最后提出优化的最优值,改善该煤矿的瓦斯抽采效果。本文的研究成果,对贵州其它煤矿进行瓦斯治理也提供了一个有益的参考。
Gas drainage improvement and optimization of drilling parameters is to improve the recovery efficiency of gas drainage, gas control in a more important. Taking a coal mine in Shuicheng Guizhou Province as an example, the borehole diameter, negative pressure drainage two borehole pumping parameters were studied by using FLUENT numerical simulation software. Finally, optimization of the optimal value, the coal mine gas drainage effect was improved. The result of this study also provides a useful reference for the Guizhou coal mine gas governance.
