sampling methods in mining

Sampling Methods MINING

At a hydrothermal sediment mined by underground mining systems, channels made from hanging wall to foot wall. Application of existing methods must be accompanied by an appropriate design. Some examples of chip sampling and channel sampling in the field application are as follows 4.a Channel sampling in test wells Used for the sediment surface.
