The number and severity of sulphide dust explosions in underground metalliferous mines have increased in recent years, despite various methods used to prevent or inhibit them. A dust explosion occurs when a cloud of combust- ible dust in an oxidizing atmosphere is exposed to an ignition source with sufficient energy to ignite the dust. A computer blast simulator model was used to investigate the movement of the fractured rock, temperatures and volumes of the explosion gases in a 70 m high, 24 m wide open stope.
