用颗粒煤渗透率确定煤层透气性系数的方法研究

Research into the method of Using Infiltration Rate of Particle Coal for DeterminingGas Permeability Coefficient of Coal Seams

本文以实验为基础，研究提出了一种用颗粒煤渗透率确定煤层透气性系数的新方法。经现场对比试验，该方法具有测值可靠、测定简便、周期短的优点。

Based on experiments, this paperputs forward a new method of using infiltration rate of particle coal for determining gaspermeability of coal seams. After a comparative test made in field, the conclusion is drawnthat the new method has the advantages of areliable result and a relatively short measuringcycle.
