systems to separate coal from rock

Splits, Coal Mining Geology, Kentucky Geological Survey ...

Sep 18, 2019  Definition: Splits are broadly wedge-shaped rock bodies that cause parts of the seam (benches) above and below the rock wedge to separate or split from each other.Depending on the direction of mining advance, these splits can also sometimes be formed by two different seams merging. Most splits are formed from flood deposits from ancient channels, including fan-shaped features called

Dry coal preparation without the use of water • STEINERT

Since the x-ray technology is capable of detecting atomic differences in the rock, the almost pure carbon in the coal is relatively easy to separate from the waste rock. And the ash content in the product can be determined by varying the threshold values. This offers a wide range of applications for the coal.
