for the purpose of Test Method D4749, (1) in the case of an underground mine, it is that coal delivered to the surface by a slope belt, hoist, and so forth. (2) in the case of a surface mine, it is that coal as it exists after it has been removed from the pit and placed into the initial means of transportation whether it be an on-the-road or off-the-road haul truck, dump hopper which feeds a pit-to-plant conveyor, and so forth.
