瓦斯抽采钻孔合理间距的数值模拟分析OA
Numerical Simulation of Reasonable Spacing of Gas Drainage Drilling
瓦斯抽采是防治瓦斯灾害的有效措施之一。本文以大宁煤矿303工作面的瓦斯赋存情况为研究对象,为煤层瓦斯流动建立了数学模型,利用Comsol Multiphysics进行数值模拟分析。研究了不同钻孔间距对瓦斯抽采效果的影响,并得出结论:确定了8m为本煤层合理的钻孔间距,此时,在抽采和经济效果两者之间得到了满意的平衡。
Gas drainage is one of the effective measures to prevent the gas disaster, Taking the NO.303 coalface the gas occurrence situation of Daning coal mine to be the study object. Using Comsol Multiphysics to conduct the numerical simulation analysis build up a mathematical model of the lfow of coal seam gas. The effects of different drilling distance on gas drainage were studied, and concluded: that the reasonable Seam drilling spacing is 8m, in this case the co…查看全部>>
