Blasting Impact on Environment and their Control Measure Techniques in Open Cast Mining

Abstract

Blasting is the most accepted and practiced technique for the breakage of rock. During blasting, the energy transformation takes place in the explosive. Rock breakage during blasting process is accompanied by the generation of ground vibrations, noise, dust, fumes and flies rock. Our paper deals with the impact of blasting on the environment which possess anger to the nearby structure transportation road and affect the people nearby the mines. Blasting operations cause several adverse environmental effects. With the development of new explosives systems and initiation devices, the blasting process has now become more efficient and safer than before. Use of software tools, blast monitoring and analysis makes it possible that damages and dangers from blasting can be predicted before blasting thus adverse impacts of blasting can be controlled and reduced. The researchers construct their empirical models based on the available research data in the field, future empirical model can also be build based on new specific site data. More than one approach to asses environmental impacts of blasting give more alternative ways to prevent the impacts. Also we have discussed different types of control blasting techniques which would help in achieving our goal and their relevance in content of India and which can be use convectively & efficiently on Indian mining sector for dealing the adverse impact of blasting with the help of virtual simulation.
