Abstract:
A material extraction system for an underground mine includes a mobile sizer for sizing removed material, an elevated bunker operable to collect the sized material, and a shuttle car operable to receive the collected material from the elevated bunker. The shuttle car is positioned substantially below the elevated bunker for receiving the collected material from the elevated bunker.
Abstract:
The present invention relates to a muck car on which a tube gasket using pneumatic pressure is installed, and particularly, to an excavated-soil transport muck car used to transport soil excavated at an excavation site to an excavated-soil storage pit, wherein the excavated-soil transport muck car has a pneumatically expanding and contracting tube gasket (20) installed at an edge thereof between a sidewall (11) of the excavated-soil transport muck car (10) and a ground surface (12) so as to prevent the leakage of contaminated water through a gap between the sidewall (11) of the excavated soil transport muck car (10) and the ground surface (12). According to the present invention, after excavated soil is loaded onto the excavated-soil transport muck car at an excavation site, contaminated water contained in the excavated soil is prevented from leaking through a gap between a bottom sidewall of the excavated-soil transport muck car and the top of the ground surface, during transport along rails over which the muck car travels, in order to significantly reduce impediments in the work environment and wasted manpower.

본 발명은 공기압을 이용한 튜브 가스켓이 장착된 광차에 관한 것으로, 굴착공사 중 발생되는 굴착토를 굴착토 저장용 구덩이(pit)까지 운반하는데 사용되는 굴착토 운반용 광차(muck car)에 있어서, 상기 굴착토 운반용 광차(10)의 측벽(11)과 바닥면(12) 사이의 모서리에 공기압을 이용하여 팽창과 수축을 하는 튜브 가스켓(20)을 설치하여, 굴착토 운반용 광차(10)의 측벽(11)과 바닥면(12) 사이 틈새로 오탁수가 유출되는 방지하는 것으로, 본 발명은 굴착 공사장에서 굴착토 운반용 광차가 굴착토를 적재한 후 광차 이동용 레일을 따라 이동하는 과정에서 굴착토에 포함되어 있는 오탁수가 상기 굴착토 운반용 광차의 측벽 하단부와 바닥면 상부 사이의 틈새로 유출되는 것을 방지하여 작업환경 저해 및 인력낭비를 개선할 수 있는 현저한 효과가 있다.
Abstract:
The invention relates to a method and arrangement for preventing the passage of preferably an unmanned mining vehicle. The invention is based on the idea of providing a mining vehicle, such as a loading vehicle, with a mast (7) arranged on its upper outer structure and extending above other portions of the vehicle. In connection with the mast there is provided an emergency stop switch. Furthermore, at the upper portion of a mine gallery, or a similar operating site, is provided a barrier boom reachable to the mast for bordering the accepted travel area of the mining vehicle. If the mining vehicle tries to leave the accepted area, the mast hits the barrier boom and thus triggers the switch arranged in connection with the mast, thereby causing the mining vehicle to stop.
Abstract:
In combination a loader unit and haul unit for use in a block caving mining operation. Each of the loader unit and the haul unit comprise a removable bucket, which can be used for loading ore. In use the bucket carrying a load of ore can be transferred from the loader unit to the haul unit so that the haul unit can transport the ore from a loading site to a crusher. The loader unit and haul unit have a respective longitudinal axis extending from the fore end to the aft thereof, and the bucket is elongate with a longitudinal axis. In use when the bucket is mounted to the loader unit the longitudinal axis of the bucket is disposed orthogonally to the longitudinal axis of the loader unit. When the bucket is transferred to the haul unit, the bucket is placed upright on the haul unit with the longitudinal axis of the bucket parallel to the longitudinal axis of the haul unit.
Abstract:
A mining machine for conveying mined material, the mining machine including opposing sides, a conveyor extending between first and second ends and a hopper assembly located toward the first end for guiding the mined material to the conveyor, wherein the hopper assembly includes modular wall sections which are detachably coupled to the machine.
Abstract:
A shaft assembly including a geared shaft extending between two bearing housings and brackets that support the housings and couple the assembly to a chassis of a mining vehicle, wherein the brackets have associated guide slots that extend transversely of the shaft and open toward an end of the vehicle so as to allow the shaft and housings to be removed or installed as a unit, lengthwise from the end of the vehicle.
