Hazard and vulnerability criteria in the rank structure of aerological risks in coal mines

Based on the risk-oriented approach, the methodology for assessing the aerological risks by ranks embracing the whole mine and its separate parts is constructed. The hazard and vulnerability criteria are defined and ranked in the structure of aerological risks. The key criteria of geological hazards are: methane content of coal seams, relative methane content of mine air, dust producibility of coal seams, content of heavy hydrocarbons in residue gases in coal seams and geothermal stage in coal deposits. The key criteria of ventilation vulnerability are depression in mine and in main drifts, air reserve of a main fan, ventilation stability and joint operation stability of main fans, hazard attenuation rate per sources, influence of fresh and return air flow direction on air leakage, influence of gas intermix activity in face zone, influence of gas kick zone on ventilation of a gateway, etc. The described methodology enables prediction and reduction of aerological risks at the stages of coal mine planning and design, operation, closure and abandonment.

Keywords: coal mine, aerological safety methodology, risk hierarchy, aerological risk ranks, methane, coal dust, hazard criteria, ventilation circuit vulnerability.
