| 摘 要： | 膨胀型软岩由于其性质的复杂性和工程的严重危害性而成为我国煤矿工程研究中最复杂的问题之一。膨胀型软岩能与水发生物理化学反应使含水量或体积发生变化，是地质历史长期作用的产物，随着时间场和空间场的不同，其力学化学特征有明显的差异，作者根据对淮南５个煤矿、铁法２个煤矿软岩的实际研究，总结二者在成份、物理化学特征、力学性质以及膨胀机制等方面的差异，为工程有效支护提供理论依据。

| Abstract: | During the last decades,paralled with increasing complicated engineering geological conditions and deformation of tunnel of swelling soft rock we are witnessing alarming phenomena in coal mine of China,The swelling soft rock in coal have become a serious problem affecting coal mines produce and building.According to geological classification and distribed regularity on swelling soft rocks,author on the basic of study of mechanical-geochemical method,discussed some characters of soft rock between Huainan and Tiefa coal mine,put forward resonable proposal on their support. |
