This book explores the technologies and developments in excavations for any Blasting practices in mines have undergone many changes in the recent past
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. Rubble is removed and the new tunnel surface is reinforced.
