<p>A haulage system (11) for pit mining essentially comprising: a head station (15) disposed at the outer peripheral surface of a pit (13), a loading station (17) disposed within the pit (13), a track (19) extending between the head station (15) and the loading station (17), a steerable haulage conveyance in the form of a pair of skips (21), and hauling means. The hauling means comprises a winder (23) fixedly disposed near the head station (15), and wire ropes (27) attached between the winder (23) and the skips (21). The head station (15) includes a headframe (95) having headsheaves (25) for guiding the ropes over the headframe (95) and to the skips (21) and a discharge station in the form of a tipping station (16). The track has a surface at a prescribed inclination to allow the skips (21) to be hauled therealong. The skips (21) are arranged to be in balance by their relative location and the winding of the ropes (27) about the winder (23). The skips (21) receive material excavated from the pit at the loading station (17) from pit trucks, convey it to the discharge station out of the pit by being hauled up along the track (19) by the hauling means, and discharge it at the tipping station (16) to be transported away by surface haul trucks. The skips (21) are supported for trundling along the track by wheels (29) incorporating resilient tyres (31) and a heavy duty suspension system. A discharge gate (221) for regulating the size of discharge material discharged from receival hoppers (35, 75) located at the loading station (17) and the tipping station (16) is also described.</p> |
