| Summary: | The article is devoted to the development of a new rapid method for determining the strength properties of rocks. A new express research method is required to meet industrial safety requirements in the operation of coal mines. The article describes the procedure for conducting research in accordance with the developed express method. The paper describes the form of the indenter used in research. The publication discusses the mechanical properties of rocks most frequently used to solve mining and technological problems in Russia. The article resolved made the choice of indicators of mechanical properties of rocks with which the establishment of a correlation dependence is required. The publication describes the used laboratory equipment. It includes a special device «PSSh 1» and a laboratory stand for determining the energy intensity of rock destruction. The «PSSh 1» makes it possible to determine the strength of rocks in wells. |
