Synopsis. Plans for large scale open pit mining of the low grade copper ore at Majdanpek Copper Mine began after a 1949 exploration revealed an extensive ore body. Mining operations and haulage systems have progressed in phases exploiting the most current technology. Phase I (1960–1980) haulage system was by trucks only.
The in-pit placement of crushing and conveying equipment results in a flattening of the pit slope of a multiple-bench open pit mine. To maximize the economic benefit of lower haulage costs associated with in-pit conveying, one must minimize the cost of the flatter slope which is expressed in terms of additional stripping or tied up ore. A computer …

By Dr. Franz Wolpers. Open-pit metal mines are often shaped like an inverted cone, with the ore and overburden being drilled and blasted, then loaded and transported by shovel-and-truck systems. Mine trucks that weigh between 106 and 260 tons, and carry payloads from 136 to as much as 400 tons, transport these materials from the pit bottom ...
Backgrounds: The transportation system within any mining project, which is responsible for delivering extracted ore to the crushing units or wastes to the wasting dumps as the destinations, poses a significant challenge in mining processes. On one hand, there are various transportation systems, notably the Truck–Shovel, the traditional …
Equipment selection is one of the most important aspects of open pit design. Mining costis mainly affected by the number and capacity of equipment. Equipment selection for open-pit mines is a major decision, which in turn, impacts greatly on the economic viability of an operation [2].Models for

1 – In an open pit operation a rotary drill is used to drill holes that are ~30cm in diameter and ~15m deep. The holes are commonly filled with ANFO (short for ammonium nitrate fuel oil) explosives. 2 – The blast pattern – drill hole location and spacing and location ‐ depends on the type of rock mined and overall mine plan.

Mining of raw materials is a process that consists of several stages. In open-pit mining, material with high compressive strength is extracted by drilling and blasting and material with low compressive strength is extracted by e. g. a bucket wheel excavator. Most important influencing factors for crusher decision are compressive …
As a result, fuel, tyre, and depreciation costs per ton increase. Owing to these factors, open pit mining at great depth (300 to 1000 m) using shovel-truck systems faces some technical and economic problems. In-pit crushing-conveying (IPCC) systems have been known in the mining industry for many decades. The idea was introduced in 1956 …
