The article presents methods for rocks strength properties determining in mining machines engineering in Russia, CIS countries and Europe. It is shown that general drawback of methods considered is lack of possibility of carrying out instant tests at various points in rock massif. Criteria are given for the method of rocks strength properties determining as applied to mining engineering tasks. Based on established criteria, the fundamentally new method has been developed. Technical devices are proposed for the method implementation in testing individual samples and rock massif. Construction of the laboratory stand estimating energy intensity of rock destruction is presented. Relationship between its value, coefficient of strength according to the M.M. scale of Protodyakonov and average particle size of the destroyed rock is shown.
