Abstract: Taking a working face of Nanshan Mine for an example, the stress state in front coal body, the permeability of coal body and the change rule of gas pressure (or gradient) distribution under the heading speed of different working faces are analyzed, and the functional relations between the parameters and distance from working face were provided. Finally, based on the analysis results, the risk of outburst for a working face of Nanshan Mine was determined by the energy source and energy dissipation theory, and the safe and reasonable tunneling scheme was provided, and the scheme was successful. The results show that with the increase of driving speed, the pre-peak region decreases, the stress concentration factor increases, the permeability near the coal wall increases, the region with high permeability decreases, the gas pressure gradient in the front coal increases, the region with low gas pressure (or content) decreases, and the risk of outburst increases.
