Abstract. Contacting features between the cutter system and rocks at drilling rocks and coals, impact of the cutter wear on redistribution of axial thrust between the cutters, and impact of the cutter relative position on the tool surface on the character of the cutter destruction in process of the rock drilling were studied with the help of mathematical modeling of process of contacting interaction between the system of cutters in the boring tool and the rocks. The equations  obtained were used for studying a process of rock-induced wearing of the cutters in augering machines. A complete set of equations was formulated for studying a process of interaction between the cutting elements of multiblade boring tool and the rocks.

Keywords: system of cutters, coal drilling, mathematical modeling, drilling of gas-drainage boreholes.
