can only be used with ore that has already been crushed. At Chuquica-mata, the in-pit and ex-pit crushers are each connected to the concen-trator plant by a pair of parallel belts. The capacity of each belt is enough to carry the output of a crusher. A belt costs about US$2,500 per meter, but the nal amount for in-pit belts is higher due to the

The deep hole blasting in open pit mine is mainly bench blasting. Deep hole blasting is a kind of blasting method which is widely used in open pit mine. The depth of the blast hole is usually 15 to 20m. The aperture is generally 75 to 310mm, while the commonly used aperture is 200 to 250mm. Features:
One 3,000 ton-per-hour system will be used for coal mining. ThyssenKrupp Fördertechnik is responsible for the full design, engineering, delivery, assembly and start-up of the plants. The world's first fully mobile crusher of this kind has been operating successfully since fall 2007 at the Yiminhe open pit coal mine in China.
This paper sets out to: examine the barriers that prevent mining companies from applying FMIPCC systems to deep pit metalliferous applications. examine potential solutions to …
This slope hoisting system accelerates transport from the mine. It can overcome an angle of repose of 50 degrees at 8 m/s. Conventional haulage will require many trucks, which can be reduced by this method. The capacity of this system can reach 4000 tonnes per hour, with a maximum depth of 300 meters.
In open pit mining two different options for extracting and hauling material have been established. On the one hand, shovel and truck only, and on the other hand, in-pit crushing and conveying (IPCC). ... While our direct-fed crushing stations are equipped with gyratory crushers, the indirect-fed stations can use any type of primary crusher ...
The methodology was applied at Chuquicamata in 2010 to choose the optimal location configuration based on the then-existing crusher system configuration and company data. ∗ To cite this article: Juan Yarmuch, Rafael Epstein, Raúl Cancino & Juan Carlos Peña (2017) Evaluating crusher system location in an open pit mine using Markov chains ...
In most open-pit mines, material haulage costs can comprise over 50% of the total mining costs. This portion can even increase as the future mining conditions will become more challenging.

Jaw crushers are the most common primary crushers used in the mining and construction industry. They are represented by a fixed jaw and a moving jaw that form a V-shaped crushing chamber. The moving jaw moves back and forth and presses the material against the fixed jaw, that in turn causes it to break down into smaller pieces.
In open-pit mines, the traditional truck-based haulage system has consumed large amounts of energy in the haulage sector for many years. The use of continuous …

The essential task of the in-pit crusher in a belt conveyor transport system is to reduce blasted material to a conveyable size. Crushers for this purpose are almost exclusively of the low crushing …
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 strength, moisture …
Gyratory Crushers are an excellent choice for a primary crusher, as they can handle very hard and abrasive material. They are ideal for dry to slightly wet material but not sticky material. Gyratories are …
Integrated continuous mining techniques such as fully mobile in-pit crusher and conveyor (FMIPCC) systems offer inherent labour, energy and environmental benefits to deep pit metalliferous mines.

Impact crushers are increasingly used for crushing recycling material. Impact crushers are capable of producing mineral aggregate mixes in one single crushing stage in a closed-cycle operation, making them particularly cost-effective. Different crusher units can alternatively be combined to process recycling material.
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 ...

Open-pit mining involves removing the layers of sand and rock found just above the kimberlite. Once exposed, the ore in the pit is broken up by blasting. ... known as a roll-crusher, may also be used to reduce the size of the ore even further. Stage 2 – Scrubbing In this stage, the ore are scrubbed to remove loose excess material and is ...
The purpose of an IPCC system is to allow the ore to be crushed in the pit and transported out using a conveyor system.
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.
Underground primary crushing station (Fig. 3) is generally fixed. It is usually located next to the skip shaft and is characterized by long service life, long infrastructure time, etc. The main equipment of the primary crushing station includes a crusher, feeder, dedusting apparatus, crane, etc. The primary crusher is mainly divided into ...
In suitable mining projects, in-pit crushing and conveying (IPCC) can provide operating cost reductions to the tune of 20 - 60% savings, depending on project specifics. For this reason, IPCC systems have been in use around the world for decades. IPCC systems consist of a primary crusher installed in-pit, close to the active mining areas.
In-pit crushing and conveying (IPCC) systems have drawn attention to the modern mining industry due to the numerous benefits than conventional truck-and-shovel systems. However, the implementation of …
RubbleCrusher hosted an open house at a landscaping company to showcase its RC150 tracked jaw crusher. Started in the U.K. in 1996, RubbleCrusher designs, manufactures and sells small crushers that are mounted on trailers, skids or tracks. The plants can be transported with a truck for ease of mobility from site to site.
