Drilling and blasting

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 of rock blasting is often known as a rock cut. Drilling and blasting currently utilizes many different varieties of explosives with different compositions and performance properties. Higher velocityexplosives are used for relatively har

Selective limestone mining without drilling or blasting

over drilling and blasting is that the limestone can be loaded directly onto trucks by means of a powerful transfer system. Eurocement makes use of further loading methods, however. If, for example, material is required for a temporary embankment stabilization, the surface miners discharge the cut limestone sideways onto a pile.
