The chute was installed in Jabal Sayid Copper Gold Project in Saudi Arabia which produces approximately 3 MTPA of ore. The underground loading chute is used to feed the underground road trains with one truck being loaded on average every 7 ½ minutes with a minimum trailer fill time of approximately 1 minute.
The ore chute is powered by a hydraulic power pack which has `fail shut’ redundancy. The arc gate and chain curtain which are used to control the flow of ore are operated through dual manual controls. The design of the ore chute was to be able to control the flow of ore using only the chain curtain, the arc gate, or a combination of both.
