  • Patent number: 4512610
    Abstract: This system develops an ore body in two lifts, driven from opposite ends (at different times) and utilizes the concept of lane pillars rather than square block pillars. These conditions generate a new ventilation system that is flexible and well suited for the varying air requirements in oil shale mining.The ore handling system is load-haul-dump (LHD) to portable crushers to belts to surface. The layout of this method introduces unique functions for this system by creating two directional ore flow from the workings, which optimize logistics and material handling methods.
