Purpose. Stress state in rock mass is the most important factor affecting processes around mine working. The methods used for calculation of stresses based on hypotheses of elastic thrust, hydrostatic state or spherical ...

Purpose. To analyze the process of rocks cutting by a tool made of polycrystallinе superhard materials (PSM). Methods. Mathematical modeling of rock destruction process. Findings. A model of deformation and fracturing ...

Purpose. To develop analytical model for a support-enclosing rock interaction to determine parameters for operational stability of deep mine workings while decreasing metal consumption and increasing efficient use of ...
