| GoldCorp Porcupine mine, located in the city centre of Timmins, Ontario, is Timmins' largest industrial operation and is located near to residential receptors. Given this, noise compliance to the Ministry of the Environment guidelines is a concern for GoldCorp. A significant source of environmental noise is the Caterpillar 785B haul trucks, which transport raw materials along the haul road and past the residential receptors. The goal of this research is to analyze and design an effective abatement plan to lessen the noise impact of the haul trucks used at the GoldCorp mine. The novelty of the research is the use of advanced noise source identification (NSI) technology and array hardware for the identification and ranking of the noise sources to eliminate the guesswork for the abatement design. The outcome is the design of a detailed and effective abatement strategy that has since been implemented on the entire haul truck fleet. |
