Mining Geology Sampling Methods: Channel, Chips, Core

As a practical example, consider an actual sampling program carried out by an experienced gold dredging company. In this case the ground had a history of superficial hand mining operations going back many years and the geologic and physical conditions indicated a possible depth and volume sufficient to support a bucket-line dredge.

Longwall mining - Wikipedia

Starting around 1900, mechanization was applied to this method. By 1940, some referred to longwall mining as "the conveyor method" of mining, after the most prominent piece of machinery involved. Unlike earlier longwall mining, the use of a conveyor belt parallel to the coal face forced the face to be developed along a straight line. The only other machinery used was an electric cutter to ...
