Abstract
Abstract Combined hazards occurring in areas of hard coal mines were characterised. A possible course of processes leading to a mining catastrophe, associated with occurrence of combined hazards, was discussed. An example of a cause and effect chain is presented, where rockburst hazard initiates – with co-occurring climatic hazard – an increase in the level of spontaneous fire hazard, methane explosion hazard and coal dust explosion hazard. Possibility of improving detection of spontaneous fire hazard in presence of co-occurring combined hazards was analysed.
