spontaneous combustion of coal stockpiles and excess fleet capacity. Further down the product delivery chain, unstable operations make it necessary to hold higher volumes of coal in stockpiles to ensure supply is always on hand, and to carry excess buffer supply at wash plants. What can the coal mining industry do to increase process stability?
