摘　　要：为了研究煤层透气性对主、被动测压法测压结果的准确性影响,通过构建测压钻孔瓦斯压力平衡过程的数学模型、结合相似性理论分析以及实验室试验,得到了煤层透气性系数对主、被动测压法的测压误差和平衡时间的影响变化规律。In order to study the influence of coal seam permeability on the accuracy of manometry results by active and passive gas pressure measurement methods,through building a mathematical model of the balancing process of gas pressure,combined with the analysis of the similarity theory and laboratory tests,we obtained the influence variation of coal seam permeability on the error of results and the balancing time by active and passive gas pressure measurement methods.
