Mine water discharge also forms the main source of various water supplies particularly potable in the thickly populated coal fields.
Industry noise. Although industrial noise is one of the less prevalent community noise problems, neighbours of noisy manufacturing plants can be disturbed by sources such as fans, motors, and compressors mounted on the outside of buildings Interior noise can also be transmitted to the community through open windows and doors, and even through building walls.Noise Pollution: Sources, Effects and Control,4. Construction Noise: The noise from the construction of highways,city streets,and buildings is a major contributor to the urban scene . Construction noise sources include pneumatic hammers, air compressors, bulldozers, loaders, dump trucks (and their back-up signals), and pavement breakers. 5. Noise in Industry:
Apr 25, 2017· Mining is the extraction of minerals and other geological materials of economic value from deposits on the Earth. Mining adversely affects the environment by inducing loss of biodiversity, soil erosion, and contamination of surface water, groundwater, and soil. Mining can also trigger the formation of The Role of Arsenic in the Mining Industry,• The mining, mineral processing and metallurgical industries support, and strictly follow, state and federal regulations to ensure protection of the environment and the health of industry workers.

Occupational noise is the amount of acoustic energy received by an employee's auditory system when they are working in the industry. Occupational noise, or industrial noise, is often a term used in occupational safety and health, as sustained exposure can cause permanent hearing damage.Occupational noise is considered an occupational hazard traditionally linked to loud Sources of Noise Pollution and Tips For Prevention of,Noise Pollution is a relative thing. In a city, it’s a jet plane taking off. In a monastery, it’s a pen that scratches. ~ Robert Orben. The acceptable amount of sound level is about 60 to 65 dBs, which equals to that of a normal conversation. Sound levels higher than 85 dBs are harmful depending on the duration of exposure and if one has hearing protection or not.

2.2. Sources of Noise This section describes various sources of noise that can affect a community. Namely, noise from industry, transportation, and from residential and leisure areas. It should be noted that equal values of LAeq,T for different sources do not always imply the same expected effect. 2.2.1. Industrial noise Mechanized industryMining Industry Profile Department of Energy,The mining industry consumed an estimated 551 trillion British thermal units (Btu) in 2002. 3 Major energy sources include fuel oil, electricity (purchased and produced on-site), coal, and natural gas. The energy-intensive nature of mining is evident by the recovery ratio of the various materials being mined.
