Abstract: An increase in the concentration level of mining operations, which is a general trend for existing and planned mines, including in Kuzbass, requires improving the preparation of coal fields for mining. The existing method is characterized by the complexity of airing the workings and high complexity. Analysis of the preparation of mine fields in the Kuznetsk basin as a whole and in individual mines of SUEK-Kuzbass JSC in particular allows us to outline the prospects for its improvement. The technical and economic indicators achieved during mining with the use of domestic and abroad produced combines with different productivity and maneuverability in the conditions of SUEK-Kuzbass JSC are estimated. The option of preparing coal fields is proposed, which exhibits a number of significant differences, the main of which is the carrying out of separate sections of conveyor and ventilation drifts and ventilation disruptions in coal pillars by combines with different productivity and maneuverability, which, in turn, allows you to unleash ongoing work in space and time, increase performance of transportation to the surface of the beaten-out coal over the mine workings while assembling and disassembling complexes of tunneling equipment in preformed chambers. Advanced technology is protected by a patent of the Russian Federation. The place of promising domestic tunneling equipment in the case of the implementation of this technology is determined.
