Green biocompatible approach to reduce the toxic gases and dust caused by the blasting in surface mining

Among all kinds of produced pollutants during blasting operation in surface mines, nitrogen oxides and carbon monoxide gases together with dust impose higher risks to the ecosystem. By the use of traditional blasting operation in surface mines a huge amount of the pollutants can be discharged annually into the mines and into the environment. To provide a safe environment for the ecosystem, a new approach was proposed as an alternative instead of the common traditional blasting approach in surface mines. Considering that environmental aspects were thoroughly observed in developing and designing the new approach, the new approach was called green biocompatible blasting approach. The purpose of developing the green biocompatible approach was to modify traditional blasting process in surface mines so that minimum environmental damage would be caused by the release of the toxic gases and dust. To achieve this goal, first, a detailed study was performed on the neutralizing substances of toxic gases and dust suppression techniques, which was presented in the form of a special pattern for blasting. Finally, the green approach was applied to compare its results with the current traditional blasting approach in the case of Sungun surface mine. It was concluded that the concentration of the pollutants using the green approach is very lower than the traditional approach of Sungun mine.
