Mathematical model of motion of gaseous products of explosion in a boring well and application for industrial safety

The article is devoted to the calculation of explosion products movement for substantiating safety of the mass blasting in mining construction materials from natural stone. A mathematical model of explosion products expiration in the boring well and its maintenance by model experiments to verify theoretical calculations are considered. Thus it is necessary to take into account the interaction of waves of pressure between the adjacent extended charges and determine the time of crack formation. Thereby the blasting safety for destruction of rocks is provided.
