Abstract
The experiment of applying the upgraded Gidrorazryv system when studying stress field parameters in the Tashtagol mine and Yubileynoe deposit (Republic of Kazakhstan) is presented. The alternative layouts of measurement stations and the features of experimental hydraulic fracturing stress measurement are discussed. The experimental estimates of stress components in the vicinity of underground mine workings are presented.
