Influence of Shift System on Coal Miners’ Fatigue

Abstract According to the job mode of shift system of coal miners, the influential factors resulting in coal miners’ fatigue are investigated, fatigue index is identified and a mathematical model is established. Using fatigue index approach and Eiichi Kiyomiya formula, the influence of Lu’an Group Shangzhuang Coal Mine's existing shift system on coal miners’ fatigue and cumulative effects are analyzed and assessed. It is discovered that the fatigue index method and Eiichi Kiyomiya formula can effectively assess the existing shift system in coal mines, and provide assessment criterion for working out more reasonable shift system.
