Vibration Levels Mining

a broadband frequency input vibration should be used in the laboratory measurements. Two levels of broadband input vibration will help to indicate the level of nonlinearity in a seat. Transmissibility data with broadband input vibration can be used only to compare different seats with each other.

exposure to whole–body vibration health related risks for operators of underground shuttle cars. Active research has also been conducted into whole-body vibration exposures for operators of underground mining equipment, and off-road heavy vehicles in mines/quarries and farming operations (Paschold & Mayton 2011).

Mining Noise and Vibration. SLR has a long history of involvement in the mining and quarrying industries ranging from EIA/EIS noise assessments, to noise control retrofitting of existing facilities to enable compliance with revised environmental objectives.

The Bureau of Mines studied blast-produced ground vibration from surface mining to assess its damage and annoyance potential, and to determine safe levels and appropriate measurement techniques. Direct measurements were made of ground-vibration-produced structure responses and damage in 76 homes for 219 production blasts.

Aims: This study aimed to monitor the vibration levels of mining machinery and duration of exposure to vibration; to study work practices of operators of mining machineries and to predict health risk from vibration exposure to operators.

If the levels of vibration are above the "action level" of 2.5 m/s 2 (meters per second per second, a measure of acceleration) for HAV or above .5 m/s 2 for WBV, and the expected duration of exposure is close to a full work shift, then it is recommended that an exposure model be constructed by taking the average time on task per day with that tool and …

vibration. The ground vibration radiates out from the hole with decreasing intensity and reduces to below levels of perception with distance. Ground vibration, at sufficiently high levels, will damage buildings but can be alarming to people inside buildings at levels well below structural damage levels.

Mining operation involves a variety of heavy rotating machinery that is used for exploration and processing of precious metals, minerals and material extracted from the earth. This industrial machinery is subjected to moderate, and in some cases, extreme vibration levels while in use.

There is no South African legislation pertaining to acceptable vibration levels or vibration exposure limits on mining equipment. The European Community Directive 2002/44/EC specifies a daily exposure limit of 5 m s −2 standardised to an 8 h reference period, and an action value of 2.5 m s −2.
