1. Introduction. Drilling and blasting is a controlled method of rock mass breakage using explosives that is commonly utilized in the mining and quarry industries, and in civil engineering constructions such as tunnels and dams (Verma and Prasad 2014, Hu et al 2017).Although rock blasting is a efficient technique for rock breakage, it still has several drawbacks such as vibration induced.Crushing is the first step in converting rock into usable products. Essentially, crushing is no than taking large rocks and reducing them to small pieces. Crushing is sometimes continued until only fines remain. Blockage incidents can be greatly reduced by supplying rock that is properly sized to match the primary jaw opening.
