Acoustic zoning for the safe use of explosives in the open pit

Rockfall in open pit mining using explosives is the most method of operation. Also, addition to technical and economic advantages, this extraction produces effects that can have a negative impact area near quarry. The blasting are such as seismic waves produce vibrations, air overpressure (noise), rock throws toxic gases. If intensity extent these not properly anticipated assessed, serious consequences occur people, civil / industrial buildings, environment, thus affecting health population stability integrity buildings slopes vicinity operations. paper describes methods assess noise produced by detonation for civilian use when removing rocks quarry, with aim ensuring degree disturbance acceptable well protection objectives mining. obtained results extracted from research study carried out opening operation new deposit, applying calculations theoretical interpretations having reference conditions established development works.
