【 摘 要 】

In the paper the most common and rapid methods of determining the strength properties of rocks in domestic and foreign practice are considered. The authors proposed a fundamentally new way of assessing the rock resistance to brittle fracture. The developed method can be successfully used to determine the properties of rocks both on samples and outcrop of the massif, as well as in the wells drilled in the massif.
