An impact panel for protecting mining equipment may include a plurality of ceramic tiles affixed to a base plate. The impact panel may further include at least one fixing hole disposed within the plurality of ceramic tiles and the base plate with a metal frame disposed around an outer peripheral edge of the plurality of ceramic tiles that is also affixed to the base plate. The impact panel may have at least one plug disposed inside the at least one fixing hole to seamlessly cover the at least one fixing hole. The panels may also be wired with sensors that will communicate with process control circuits allowing data collection on remote process and remote mining equipment

Disclosed are vehicles used in transporting coarse ore in a mine and systems using the same. The vehicles include a drive mechanism for moving the vehicle along a surface; an inclinable conveyor positioned atop the drive mechanism for moving the coarse ore from a loading position to a discharge position; and vertically extending walls positioned along the longitudinal sides of the conveyor. The loading position of the conveyor being offset from the vertically extending walls and the discharge position of the conveyor extends beyond the vertically extending walls so that one vehicle can be positioned with respect to another to form a continuous walled conveyor. The vehicles and systems described herein do not require rails, so they can be manoeuvered within a mine to form a network from the mine face to a coarse ore unloading area.

The present invention discloses a mine exploitation, separation, filling and treatment exploitation method, including main sources of gangue on a small-volume gangue exploitation working face and gangue reducing measures; system layout, equipment and separation technology for coal gangue separation; system layout, equipment and production technology for filling synergistic caving type coal efficient stoping; pretreatment and pre-control measures for environmental influence before and after gangue filling; and design principle and design steps of the mine exploitation, separation, filling and treatment exploitation method. The method not only solves the problem of long-distance transportation of gangue, reduces the lifting cost of underground gangue and relieves the pressure of mine auxiliary lifting and ground coal washing plants, but also may effectively treat coal mine gangue, reduce the surface stacking area of coal gangue, reduce the damage to the ecological environment of a mine and protect an ecological environment. Furthermore, a gangue filling and coal efficient stope face has high single production efficiency, may meet the requirements of modern mines for production capacity, and application prospects are wide.

A rock feeder deflector device for a rock feeder used in underground mining applications. The rock feeder has a material transport portion for transporting rock material to a conveyor. The rock feeder deflector device comprises a mounting portion configured to be connected to the rock feeder; a guiding plate movably connected to the mounting portion; and a moving mechanism arranged between the mounting portion and the guiding plate. The moving mechanism is configured to move the guiding plate relative to the mounting portion between an operative position configured to guide rock material to the material transport portion and an inoperative position.
