Blasting is the process, where explosives are used to fragment the rock mass, so that loading equipment can handle the fragmented rocks. The main objective of blasting is to fragment and displace the rock mass (Mehrdanesh et al. 2018).Nevertheless, in these operations, a huge amount of explosive energy is not used in actual fragmentation and creates number of blast nuisances, such as blast

For decades, the method of drilling and blasting was used to extract the Limestone. After that, it used to be wet-processed into clinker in the concrete plant. But this process used to be extremely expensive. So now the dry mining process is preferred for the production of the clinker as it minimizes the consumption of the fuel per ton of material.

Mining wastes is generated during the process of extraction, beneficiation and processing of minerals. Extraction is the first phase that consists of the initial removal of ore from the earth. This is normally done by the process of blasting, which results in generation of large volume of waste (soil, debris and other material).
