【摘要】 径向流量法是目前我国使用得最为广泛的一种煤层透气系数测定方法 ,但其透气系数计算存在着 2个问题 :其一是有时无法找到适当的计算公式 ,其二是有时又可以得到 2个互相矛盾的结果。文章详细剖析了这些问题的根本原因更多还原

【Abstract】 A radial flow method is a widely applied measuring method of seam permeability coefficient in China. There are two problems in the calculation of the permeability coefficient. One is difficult to get a suitable calculation formula some times and the others may have two contrary results some times. The paper had a detail analysis on the basic causes of those problems.更多还原
