Mining Methods Rhino Resource Partners

Underground mines in the United States are typically operated using one of two different methods room and pillar mining or longwall mining. In room and pillar mining, rooms are cut into the coal bed leaving a series of pillars, or columns of coal, to help support the mine roof and control the flow of air. Continuous mining equipment is used to cut the coal from the mining face. Generally

To assess the potential effect of risk management on injury rates for each of our partner mines, we compared their 25-year injury rate trends to mines of similar employee size and total production (for coal mines only). We used annual injury and employment data reported to the Mine Safety Health Administration (MSHA) between 1989 and 2012 to calculate injury rates. These data include mining
