However,there are many factors that influence the hydrofracturing effects,including geological characteristics,physical properties of reservoirs and energy of strata.

During the process of studying tectonic origin of Gold-bearing breccia bodies in the Shuangwang gold deposit ,Shanxi province, the author apply several modern tectonics theories, such as hydrofracturing, fluid dynamic breccia, tectonic pumping, deformation partitioning, embryonic fracture etc.

Opening point, opening angle and maximal tangential stress on ellipse edge are presented under uniaxial compression, biaxial compression and uniaxial compression with fissure water pressure respectively.

According to elastic mechanics theory and Mohr-Coulomb rule, this paper quantitatively studies fissure water pressure, which causes sliding of horizontal strata in the Three Gorges reservoir area.
