There are several activities that result in coal losses, the amount of coal loss is 685 tons so the mining recovery is 98.74%. Coal loss in pit 15 occurred due to incomplete coal mining, coal re-cleaning, scattered coal not directly transported to the stockpile, waterlogged loading points, coal weighing, and distance of coal survey data collection.
