P&Q University Lesson 4- DrillingBlasting : PitQuarry

2019-8-28  Blasting is heavily regulated and watched by federal, state and local agencies. In terms of processing, blasting is the critical first step in the rock-fragmentation process. Maximum profitability depends largely on an optimized blast. Consider that drilling and blasting are the first operations performed in any hard rock quarry operation.
