Explosion simulation provides a good opportunity to identify and investigate the movement of fire in the mine network, as well as relative information about the time it takes for fire to reach different parts of the mine. For this purpose, in this part, according to the accident hotspots in the lower malach aram mine, a simple explosive mass has been simulated and the movement of this explosive mass and the time of its arrival to important parts have been investigated. Due to the proximity of the two faces and extractions of tunnel 7 and gas flow and the high rate of extraction face, the first site is considered to simulate the explosion. Data collection and analysis of this explosion has been done for three main points, namely the mining face of tunnels 1 and 2 and the moment it reaches the highest level of the mine. Finally, the simulation results are discussed.
