Field Experiment of Reducing Explosive Gas and in Deep Open Pit Mine

The composite method of field experiment and numerical calculation is used to study the effect of filling the shot holes with surface-active detergent solution to reduce the explosive gas and dust in open-pit mine. The result shows that the volume of explosive gas and dust can be decreased 50% by using surface-active defergent solution instead of rock cuttings to fill the shot holes. This technique reduces environment pollution in deep open pit mine.
