| Abstract: | s:The ratios of rock's compressive tensile strength is much greater than one, which is one of the important differences between rock and metal. From the ambient stress states of ellipse pore, it has discussed the process of micro ellipse developing to excellent cracking and then to plane of fracture. The formulation has been obtained between ratio of rock's compressive tensile strength and angle of internal friction. |

| Keywords: | Rock strength ratio of rock's compressive tensile strength angle of internal friction obliquity of fracture plane |
