Environmental implications on blasting operations in Indian quarry mines

In conventional opencast mining, blasting plays a significant role in mining activity. Basically, blasting is done in mining activity to create fragmentation. In the process of fragmentation via blasting, a lot of side effects arise. The prominent side effects include flyrock, airblast, and ground vibration. Also, the fragmentation size desired by mine owners differs for different minerals. So, usage of the type of explosive and quantity of explosive should be optimum, as it results in an increased magnitude of side effects such as flyrock, airblast, and ground vibrations. Like how space, burden, stemming material type, and stemming column height do affect all of the aforementioned negative effects. In this article, a case study of Indian mines measures the unfriendly impacts of blasting in opencast mining.
