What is the average weight of solid coal per cubic foot?

The average weight of solid coal per cubic foot is approximately 80 pounds. This figure is derived from the typical densities of different types of coal, which can vary based on factors such as moisture content and coal grade. However, a commonly accepted average value is around 80 pounds per cubic foot, which helps in estimating transport, storage, and processing requirements in mining operations. Understanding this weight is crucial for mine foremen and operators when planning for the efficient handling and transportation of coal to ensure safety and adherence to operational guidelines.
