CTIVITY ACCOUNTING TECHNIQUE FOR ENVIRONMENTAL NOISE ASSESSMENT IN MECHANIZED SURFACE MINING

摘要

The authors have developed the Activity Accounting Technique for predicting far field noise levels due to operation of specific set of mining machinery. The technique is based on the breaking down of the mining oeprations into a number of activities and establishing their duration and average lcoation. By estimating the noise levels due to these activities, the overall noise field near a surface mine can be predicted. Experiments wee undertaken at a quarry to validate the model developed based on this technique. Results of these experiments are discussed in this paper.
