Chuquicamata Subterránea. After more than 100 years of production, Codelco’s Chuquicamata, one of the greatest open-pit copper mines, which is located in northern Chile, will deplete its surface minable reserves and move to underground production by 2018. This is a significant milestone for one of the world’s largest copper producers.

The production cycle of open-cast coal mines generally includes drilling, blasting, loading, hauling and coal preparation activities. Individual optimization of these activities does not mean that the whole system is optimized. This paper proposes a cost model considering all activities in mining cycle and system-wide approach to minimize the total mining cost of bench production. Since the

Todays open pit mines operate in ever-more-remote locations under harsh conditions. They need to manage increasing transport distances. And they face volatile raw material prices and increasing energy costs. In this situation, control over energy performance and equipment condition becomes key. Digital mining can help.

(a) open pits are getting deeper requiring lower mining cost solutions, and (b) there is increasing pressure on mining companies to reduce carbon emissions. In-pit crushing and conveying (or IPCC) is a potential solution for both issues. And when we say potential, we mean that it will not work for every case.

At the Spruce mine on the Mesabi range, a conveyor system was installed during the summer of 1937 to handle open-pit ore. Part of the ore is mined by electric shovels that load into trucks, which deliver it to a raise driven from an underground level to the bottom of the pit.

Opening a new mine or expanding an existing operation can be a challenging and daunting task. Aside from assessing and evaluating social-environmental concerns and designing the mining and material movement approach, the first question often asked is, "how much will it cost us to mine?" This may need to be determined even before you decide that

Open-pit mining is the process of extracting rock or minerals from the earth through their removal from an open pit or borrow. Figure 8.8. Open-pit mine [16]. Surface mining is usually used to develop coal seams and deposits of many other minerals, but their feasibilities vary with the nature of the body ore.

These components, too, originate from vertical conveying and allow for transport of material over inclines of up to 90 degrees. RopeCon can also be extended in line with the axis of the conveyor belt. As the open pit mine grows and changes, the loading or discharge point can be adjusted flexibly along that axis to meet the new requirements.

Open-pit mining clearly offers a number of economic advantages over underground mining, especially now that mineral-processing technology has advanced to the stage where very low-grade ores can be treated profitably. 100 to 150 years ago, this was not the case, and mining was still much more selective.
