Sampling Methods MINING

This method can be used in the sediment contained in the surface and also in an underground mine. For shallow sediments, this method is used in a test well. Groove (channel) is made on the side of the test wells. At a hydrothermal sediment mined by underground mining systems, channels made from hanging wall to foot wall.
