The article puts forward a 3D modeling method for diffusion ventilation processes in coal mines and an innovative methodical approach to mine ventilation system design. The proposed method enables locating probable gas accumulations, determining increased temperature, dust and moisture content and evaluating endogenous fire risk based on aerologic factors. The method application will ensure reasonable control of the listed parameters under different ventilation modes and mining systems, including critical and emergency situations. Furthermore, the new method will assist in selecting optimized modes of degassing and gas suction. The method involves construction of an aero- and gas-dynamic model of a mine or a mine area, which, given the proper maintenance and upgrading in conformity with the actual mining front advance, is a tool of air safety control. The method uses modern computer technologies of three-dimensional modeling of gas-dynamic processes in porous media.

The study has been supported from the federal budget for R&D (basic and applied research and development) Program No. 36 in the framework of the main part of research project state assignment No. 2014/113.
