摘　　要：瓦斯抽放是解决煤矿瓦斯问题的一项重要措施．但是，由于煤的赋存条件千差万别，有些煤矿本煤层抽放效果一直不很理想．交叉钻孔抽放本煤层瓦斯正是在这种条件下产生的．本文通过对某煤矿交叉钻孔抽放瓦斯的研究，应用ＲＦＰＡ＇９８软件，得出了该种条件下合理的交叉钻孔垂直距离．The methane migration is an important method in solving coal mine methane problem. But because of the different conditions of the coal existing state, the migration effect is not good in coalseam in some coal mines.The migrating methane by cross-borehole in coalseam is used in this condition. By researching the methane migration by cross-borehole in coal mine, the paper gets the reasonable cross-borehole vertical space in this condition by using the software of RFPA'98.
