    • A surface mining system for mining successive, generally parallel cuts in a coal or similar mineral seam includes at least one endless belt conveyor disposed on a spoil pile directly adjacent the cut being excavated and a second conveyor extending from the first conveyor to a material storage site. Material is transferred to the first conveyor by an excavator working the longitudinal extent of the cut and transferring excavated material to a moveable crusher and conveyor apparatus which transfers the material to a second moveable crusher and conveyor apparatus. The second moveable crusher and conveyor apparatus discharges material onto the conveyor disposed on the spoil pile. The mineral seam may be mined by progressively advancing into the seam with successive parallel cuts and progressively moving the conveyor system onto newly formed portions of the spoil pile. A combination conveyor and crusher apparatus is arranged such that the conveyor and crusher unit are mounted on an undercarriage in counterbalancing relationship to each other.
