Noise problem and its control for heavy earth moving machinery deployed in opencast mines - A critical review

Abstract

Worldwide, increasingly stringent regulations are coming into force, limiting the exposure of workers to industrial noise. Industrial noise and its consequences, is thus growing importance to employers, local and central government officials, trade unions, occupational hygienists and physicians and insurers. India is not an exception far this. The mining industry in India is facing serious problem of noise due to increasing demand of minerals for which large capacity machines are being deployed producing high noise levels. The present paper thoroughly reviews the noise problem and its control for heavy earth moving machinery's deployed in opencast mines both in India and worldwide. The various noise control approaches for heavy earth moving machinery's deployed in opencast mines are also discussed.
