The method selected will depend upon a number of factors, including the equipment at hand and the depth of the rock in the earth. Secondary blasting is noisy and generally produces many flying fragments.

    1. Introduction. Based on conventional blasting technique, the air in the bored holes is replaced by confined medium for confined blasting technique, with the purposes of increasing the resistance of propagating medium wave, reducing the energy loss, increasing the efficiency of limited explosive, improving the directional effect, and fully utilising the crack-magnifying effect Cited by: 9. Drilling and blasting is the controlled use of explosives and other methods such as gas pressure blasting pyrotechnics, to break rock for is practiced most often in mining, quarrying and civil engineering such as dam, tunnel or road result of rock blasting is often known as a rock cut..
