Blasting Quarry Used

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 of rock blasting is often known as a rock cut.. Drilling and blasting currently utilizes many different varieties of

Blasting Quarrying and the environment Quarrying

Blasting is necessary to break rock from the ground, prior to it being taken for processing. In the early days of aggregate quarrying, explosives were not used particularly scientifically although some attempts were made to optimise use to minimise cost and maximise output.

Quarry Wikipedia

01-04-2003· Stone quarry is an outdated term for mining construction rocks (limestone, marble, granite, sandstone, etc.). There are open types (called quarries, or open-pit mines) and closed types (mines and caves). For thousands of years, only hand tools have been used in quarries.

The massive use of blasting agents such as ANFO, Heavy ANFO etc., in rock breakage has brought about an important development of initiation and priming techniques. This is due to, on one hand, the relative insensitivity of these compounds and, on the other hand, a desire to obtain maximum performance from the energy released by the explosives used in the process.
