WhatsApp: +86 18221755073The mining industry's management of noise from mining operations is recognized as a fundamental responsibility. Implementing a noise management system that includes noise surveys, day and night noise mitigation, and some level of noise monitoring is a primary function that is required to meet environmental impact standards in most locations.
WhatsApp: +86 18221755073The operation of large mobile crushers plus screens and processing plants along with explosive blasting gives rise to high levels of noise, potentially affecting both workers and residents in the surrounding areas.
WhatsApp: +86 18221755073The new rule requires that mine operators enroll miners in a hearing protection program if they are exposed to an average sound level of 85 decibels (dBA) or more during an eight-hour period. In order to determine average sound level, workplace noise monitoring is required.
WhatsApp: +86 18221755073Repeated noise exposure and occupational hearing loss are common health problems across industries and especially within the mining industry. Large mechanized processes, blasting, grinding, drilling, and work that is often in close quarters put many miners at an increased risk of noise overexposure. In stone, sand, and gravel mining, noise is generated …
