==Ore removal== In mines which use rubber-tired equipment for coarse [[ore]] removal, the ore (or "muck") is removed ("mucked out" or "bogged") from the stope using [[Articulated vehicle|center articulated vehicles]]. These vehicles are referred to as "boggers" or [[LHD (Load, Haul, Dump machine)|LHD (Load, Haul, Dump machines)]]. These pieces of equipment may operate using [[diesel engine]]s or [[electric motor]]s, and resemble a low-profile [[Loader (equipment)|front end loader]]. Electrically powered [[LHD (Load, Haul, Dump machine)|LHD]] utilize trailing cables which are flexible and can be extended or retracted on a reel. <ref>http://www.mineweb.com/archive/greGreener underground mining{{Dead link|date=June 2023}}</ref> In shallower mines the ore is then dumped into a truck to be hauled to the surface. In deeper mines, the ore is dumped down an ore pass (a vertical or near vertical excavation) where it falls to a collection level. On the collection level, it may receive primary [[crusher|crushing]] by a jaw or cone crusher, or by a [[rockbreaker]]. The ore is then moved by [[conveyor belts]], [[truck]]s or occasionally [[trains]] to the [[Shaft mining|shaft]] to be hoisted to the surface in buckets or [[skip (container)|skip]]s and emptied into bins beneath the surface [[headframe]] for [[transport]] to the mill. In some cases the underground primary crusher feeds an inclined conveyor belt which delivers ore via an incline shaft direct to the surface. The ore is fed down ore passes, with mining equipment accessing the ore body via a decline from the surface.
