摘　　要：为探索采用气体渗透率k值评判地层漏失特性的可行性,对某岩石断面侧壁8组25个钻孔开展了原位气体渗透率检测与钻孔压水试验。对钻孔压水实验结果与气体渗透率检测结果开展了对比研究。结果表明,钻孔中透水率q<5Lu,对应气检渗透率k一般在10-14 m2量级或更低;钻孔中透水率q在8～35Lu,对应气检渗透率k在10-13 m2或10-12 m2量级。In order to explore the feasibility to judge the characteristics of underlying loss using the gas permeability k value, the two testing methods, in-situ gas permeability testing and water pressure testing in borehole, base on the 25 drilling holes which were plot for 8 groups at the flank of a sap,were adopted for comparing in the experimentation. The results showed that when the absorption rate q was less than 5 Lu in borehole, the corresponding gas permeability rate k was generally at the level 10^-14 m2 or lower, and when the absorption rate q was about 8-35 Lu, the gas permeability rate k was from the level 10^-13 m2 to 10^-12 m2.
