Drilling and blasting - Wikipedia

Drilling and blasting is the controlled use of explosives and other methods such as gas pressure blasting pyrotechnics, to break rock for excavation It is practiced most often in mining, quarrying and civil engineering such as dam, tunnel or road construction The result ofdrilling and blasting process - ugcnetnic,The drilling and blasting process, the loading and hauling process, and the ventilation process are responsible for 29%, 36% and 31% of such emissions respectively The production of explosives and its blasting on site causes 73% GWP emissions in the drilling and blasting processExcavation Process Drilling, Blasting, Excavation - YouTube,05/12/2013 · Excavation Process Drilling, Blasting, Excavation
