摘要
Abstract
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 coal mine has obtained a satisfactory balance not only in the drainage effect but also the economic effect .关键词
