The article presents the results of the analysis of factors causing methane and coal dust explosions in dead headings. With a forced ventilation method the explosive atmosphere migrates in a hazardous zone of the face area, where sources of ignition are strongly suspected. With an exhaust ventilation method the sources of explosion hazards, which are typical of a forced ventilation method, are not available. Experimental data is provided supporting the effectiveness of the removal of combustible substances from dead headings by an exhaust ventilation method.
