Abstract
Clay rocks may exhibit brittle behavior, such as mudstones and siltstones, as well as high ductility, that is especially the case when water phase is considerable. Examination of the failure behavior of heterogeneous rock mass at macrolevel suggests that failure behavior and fracture opening depend substantially on the stress state of the rock mass, its structure and stimulation method. Experimental studies have revealed that stress-strain behavior of clay and siliceous shales depends greatly on water content. Ability of clay and siliceous rock samples to develop new surfaces has been studied experimentally. This ability has been found to correlate with fraction of the colloidal component.
