摘要
膨胀型软岩由于其性质的复杂和工程的严重危害性而成为当前岩石力学和工程地质学领域中最复杂的理论和工程问题之一。膨胀型软岩系指那些能与水发生物理化学反应使含水量或体积发生变化的软岩。由于不同煤矿工程的膨胀型软告形成的地质时代不同，成岩胶结程度不同，成因类型和发育规律的差异，而导致其力学化学行为也有明显差异。因此所选择的支护方式也不一样。软岩工程地球化学行为的研究，既要注意环境应力对岩石性质的影响，更要重视岩石在环境应力作用下所发生的一系列物物理化学变化对岩石自身性质影响的研究。
During the last decade,paralled with increasing complicated engineering geological conditions and deformation of tunnel of swelling soft rocks we are witnessing alarming phenomena in the coal mine of China.The coal mine swelling soft rocks have become serious problems affecting coal mines produce and building.The problems arise fromincreasing the deepth of coal mines,the complicated engineering geological conditions,thelack and bad quality of swelling soft rock geological conditions, the so-called damage doneby environment engineering stress and the mechnical-geochemical properities of theswelling soft rocks. According to geological classification and distribed regularity onswelling soft rocks.According to geological classification and distribed regularity onswelling soft rocks. author applied mechanical-geochemical method, to divide swelling softrocks into three types of geology (P, M and C type), put forward reasonable proposal ontheir support in P, M and C type's swelling sort rocks.
