EQUIPMENT NOISE AND WORKER EXPOSURE IN THE COAL MINING INDUSTRY By Eric R. ,,1 Daniel R. Babich,1 and Jeffrey R. Vipperman, ABSTRACT Prolonged exposure to loud noise can cause permanent damage to the auditory nerve and/or its sensory components. Despite regulations and efforts by government and industry to reduce noiseinduced

Managing noise in the coal industry to protect hearing Noise can be described as 'unwanted sound' or as 'sound of such intensity or character sufficient to disturb and/or discomfort the listener'. 'Coal mining has the highest incidence rate of [industrial deafness] claims in all the industries examined – nearly
These areas are indicated by localized high noise levels. For instance, Figure F–1 reveals a higher noise level at the second row of fine coal screens. This area should be investigated by mine management to determine the cause/source of the higher noise level, then dealt with appropriately.
Planetary Type Reduction Gear for Coal Mills. BCH type compressor with radially split (barrel) casing are used for the light gas, such as hydrogen gas, and for the high pressure of about 4 to 35MPa. And stable operation at the high speed to about 15,000 rpm is possible.
In the future, coal movement by railroad is expected to increase to 250 million tons per year in 1985, 470 million tons per year in 1990, and 650 million tons per year in 2000. The projected overall amount of western coal moved represents a rate of increase of % per year from 1980 to 2000.

Noise and Vibration Assessment – Muswellbrook Coal Company EIS EXECUTIVE SUMMARY A Noise and Vibration Assessment has been conducted for the Muswellbrook Coal Company Limited's No. 1 Open Cut Extension proposal. The study addressed the following noise and vibration issues: ... Noise level percentiles are explained with the aid of a diagram of a
The noise of ball mill is decomposed using wavelet packet. The eigenvectors reflecting coal level of mill can be obtained from wavelet packet parameters. Through neural network training, the statistical model of coal level and ball mill eigenvectors is established.

The ability of a coal power plant to accommodate significant changes in fuel quality is often limited by many constraints. When faced with a challenging goal to test torrefied biomass fuel at its ...
Exposure to elevated noise levels can cause not only noiseinduced hearing loss, but also physiological stress, fatigue, cardiac abnormalities, and other health concerns. The noise standard established by MSHA requires the noise exposure level (NEL) for miners to be a timeweighted average not greater than 85dBA for an 8hour exposure. At ...
The utility model relates to a coal mill bearing lubrication system, and aims to solve the problems that in the prior art, when a coal mill bearing lubrication system operates, owing to long operating time of an oil pump, mechanical wear is high, oil amount is adjusted frequently, since oil excess, oil lack or oil finish occur often, bearings can be burnt, equipment can be damaged, environment ...
The noise levels in coal washeries, coal preparation plants, open cast and underground mining centres are very high when compared to accepted limits for occupational noise exposure. Even the residual noise level when there is minimal activity is 80 to 82 dB.
