Challenge: Assessment of benefits of replacing the existing haul truck fleet with a conveyor system to reduce transportation costs.
Solution: Marston's study confirmed the existing truck/shovel approach thus providing Chanute with the most economic alternative for moving limestone and shale from the quarry to the cement plant at this location.
Challenge: Balance ore availability while minimizing waste stripping costs.
Solution: Marston developed a geological model that helped lower the cost by reducing stripping requirements.
