摘要
在分析影响煤层透气性因素的基础上,利用钻孔径向流量法及其透气性系数计算公式对盘江矿区各开采煤层的透气性进行了评价,评价结果表明,盘江矿区目前开采的3,5,12,17,18号煤层均为低透气性煤层。
On the basis of analysis on the infecting factors of gas permeability of coal seam, the gas permeability of coal seams which are being mined at present in Panjian mining area is evaluated using borehole radial flow method and the formula for gas permeability coefficient of coal seam. The results indicate that the gas permeability of 3,5,12,17,18 coal seams is low in this mining area.
