Channel Sampling - Maptek

2020-4-6  Because channels are sampled at different angles from the vein, it is difficult to efficiently establish the actual minimum width based on the channel orientation, vein azimuth and dip. How does it work? Channel Sampling uses a compositing method to obtain the actual channel length that represents a minimum mining width.

Mining Geology Sampling Methods: Channel, Chips, Core

2016-11-3  Drift Mine Sampling. Underground mining procedures are collectively known as “drift mining” where applied to placer gravels. Placers buried under deep masses of low-value gravel or capped by lava flows have been extensively worked in this manner. Drift mining presupposes the concentration of values in a well defined stratum or channel.

Sampling Methods MINING

2021-8-15  CHANNEL SAMPLING 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.

Grab Sample - Mining Fundamentals

Other mining sampling methods are bulk sampling, channel sampling, and chip sampling. The results of all these methods are combined in order to determine the grade of the ore body. Grab sampling is often a double check on the chip or channel sampling methods. Apart from ore sampling, grab sampling may also be extended to the air sampling that ...
