Skips are shaft conveyors for hoisting ore/coal or waste from the underground. The most significant feature is the method by which ore/coal is discharg ed from the skip. Skips now in use are almost always the bottom-dump design. Skip loading is often automated in conjunction with automated slumping and automated ore/coal hoisting systems.

Therefore, run-of-mine (ROM) coal—the coal that comes directly from a mine—has impurities associated with it.
