A Critical Study on the Underground Environment of Coal ...

2013-6-15 · 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
