摘　　要：选取贵州发耳煤矿作为研究对象,通过数值模拟与实践观测相结合,研究影响抽采邻近层的穿层钻孔抽放效果的主要因素,从而确定最优的抽采参数,提高瓦斯抽采效率,减少了不必要的资金浪费。Guizhou Faer Coal Mine was taken as the research object to study the mare lntlu- encing factors of boreholes through coal seam on gas drainage in the adjacent coal seam by the aid of the numerical simulation and practice observation. The optimum drainage parameters were de- termined to enhance the efficiency of gas drainage and the unnecessary fund waste was reduced.
