Mining is a highly variable environment where process bottlenecks can shift multiple times within a shift. disruptions to regular operation like shovel breakdowns congestion at dumping points or changing dig conditions require quick and coordinated reactions between shift leaders dispatchers and front line supervisors to minimize production ...
Most mining haul routes consist of four main components: loading loaded hauling dumping and unloaded hauling to return to the loader. these components can be modeled together as servers in one cyclic queuing network or independently as individual service channels.
Or approximately 800 million tonnes in 2015 using a fleet of large haul trucks and shovels. the mining and maintenance costs alone to move this material will be approximately 1.3 billion. the cost of loading and hauling the material will be approximately half that cost and represents the single largest cost of producing steelmaking coal.

Surface mines. in a surface mining operation materials handling system is composed of loading hauling and dumping. shovel-truck systems are most common in open pit mining. shovel-truck refers to a load-haul-dump mining system involving any combination of loading units and trucks. the most important factor in every operation is profitability.
Surface mining process somewhat varies depending on how the target mineral deposit is situated e.g. horizontal inclined or interbedded but commonly includes the following four steps: 1 top soil removal 2 overburden removal 3 extraction of ore and 4
The loading and hauling machines choice are made based on the deposit characteristics and geometry of loaders or shovel and trucks. selection of both loaders or shovels and trucks begins with loaders or shovel; this is because trucks performance is influenced more by the loaders choice than vice versa.
Then it selects the ideal location to assign trucks for maximum productivity of both trucks and shovels. equipment operates in a steady flow rather than bunching together in queues waiting to load or worse leaving shovels hanging. this feature of wencomine has proven to increase mine output at least 11 — without a single additional haul ...
