Abstract

The aerodynamic model of a mine ventilation network including face space of preliminary development has been developed with the use of quasi-analog simulation analysis of the object, based on consideration of a multistage nature of gas dynamics. The model allows finding: solutions to permeability filtration of gas in outburst zones of face spaces, equivalent aerodynamic characteristic of sudden gas outburst; distribution of discharged gases between mine openings and finding zones and openings where fan reversal and accumulation of methane of explosive concentration is possible. This paper addresses the modeling of permeability filtration of gas in outburst zones of coal mine face spaces.
