Abstract

Ergonomics application on underground miner’s health plays a great role in controlling the efficiency of miners. The job stress in underground mine is still physically demanding and continuous stress due to certain posture or movement of miners during work leads to localized muscle fatigue creating musculo-skeletal disorders. A good working environment can change the degree of job heaviness and thermal stress (WBGT values) can directly have the effect on stretch of work of miners. Out of many unit operations in underground mine, roof bolting keeps an important contribution with regard to safety of the mine and miners. Occupational stress of roof bolters from ergonomic consideration has been discussed in the paper.
