Stratified and vein deposits dipping at angles; greater than the angle of repose of the spoil so that overburden cannot be deposited within the pit.

احصل على السعرMost modern mining methods allow the coal miners to reach the nation’s coal reserves and produce around three times more coal within an hour. Methods of Removing Coal. Coal is usually removed using three main methods; Surface mining is ideal when the coal is less than 200 feet in the ground. In this case, the large machines will help
احصل على السعر4.3.1: Surface Mining Methods. Surface mining methods are traditionally divided into two classes: mechanical and aqueous. Mechanical methods rely on breaking the ore by mechanical means, and aqueous methods rely on the use of water or another solvent, e.g. an acid, to break down the ore and facilitate its removal.
