Abstract: A fire of a mining dump truck increases the risk of tyre explosion. Mining equipment is extinguished by auxiliary mine rescue crew and mine rescuers who approach it at an unsafe distance. A tyre explosion creates a number of additional hazards that can lead to serious injury or loss of life. Studies indicate that such injuries primarily include barotrauma, eye and general bodily injuries caused by the impact of destroyed wheel elements. A methodology for calculating safe distances is required to ensure the safety of rescue work in open pit mines and quarries. The proposed methodology for estimating safe distances, which was developed based on conditions of a pressure vessel explosion, will reduce the risk of injuries to mine rescuers and members of auxiliary mine rescue crews. The use of existing protective equipment or development of new ones is justified by the presented analysis of injuries such as temporary loss of hearing, eardrum ruptures, brain contusions, loss of consciousness, internal injuries, dislocations, broken limbs and other types of injuries that are caused by tyre explosions.
