This paper tries to model the production and operating cost uncertainties associated with the in-pit crusher location by using the stochastic facility location model.
Open-pit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of open-pit mining. The removal of this material is known as stripping.

6 Common Blasting Methods in Open Pit Mining. We know that open-pit mining operations mainly include drilling, blasting, mining, transportation and dumping. Blasting is a very important part of it. Blasting costs account for 15% to 20% of the total cost of open pit mining. Moreover, the quality of blasting directly affects the working ...
In such cases, it is necessary to find suitable alternatives, among which continuous mining systems such as In-Pit Crushing and Conveying (IPCC) systems stand out.
With the trend of open pits becoming broader and more profound in scale continuing, the potential of In-Pit Crusher and Conveyor (IPCC) systems to save costs deserves new tools to make the study of its practical comparison against more traditional truck/shovel systems more accessible and feasible.

Open-pit mining provides significant proportions of many of the world's major mineral commodities. In hard rock mining, much of the world's annual output of copper, gold and iron ore is won from open-pit operations. Other commodities produced from open-pit mining include diamonds, molybdenum, manganese, lead and zinc, uranium and a …
In this paper, a quantitative simulation-based approach is developed for managing the risk raised from locating the primary crusher at the edge of open-pit mine because of price uncertainty.
Facility site selection, (such as Primary or in pit Crusher location) is one of the most important steps in mine design process that has a significant impact on economy of the mining operation.
A methodology is presented for deciding the location of a third ore crusher to be installed at Chile's Chuquicamata copper mine. The proposed approach determines which location alternative exhibits the minimum capital and operating costs when equipment failure probability is considered. Two alternative location configurations are …
Lizotte [1] affirmed that equipment selection affects economic considerations in open-pit design, particularly showing overburden, waste rock and ore mining costs and cost escalation parameters as a function of plan location and depth. Mining costs are a function of site conditions, operating scale and equipment.
To choose the type of crusher, consider the following factors: Material characteristics: The type of material being crushed, such as limestone, concrete, or granite, will impact the selection of a ...
Choosing a suitable location for a crusher in open pit mining requires careful consideration of several factors such as ore quality, grade, capacity, throughput, and …
When choosing a small rock crusher for mining, you need to consider several factors: Output size: The size of the rocks that the crusher can produce will depend on the size of the crusher and the ...
A methodology is presented for deciding the location of a third ore crusher to be installed at Chile's Chuquicamata copper mine. The proposed approach determines which location alternative ...
Open pit mining is defined as the method of extracting any near surface ore deposit using one or more horizontal benches to extract the ore while dumping overburden and tailings (waste) at a specified disposal site outside the final pit boundary. Open pit mining is used for the extraction of both metallic and nonmetallic ores.
The methodology was applied at Chuquicamata in 2010 to choose the optimal location con guration based on the then-existing crusher system con guration and company data.
The remaining deposits are located at depth, with no easy access, which requires high initial capital costs (Osanloo, 2012). Mining at great depths and high tonnages is possible only through open pit mining. Today, more than 80% of open pit mines in the world use a shovel-truck system for loading-hauling operations (Osanloo, 2010).
A methodology is presented for deciding the location of a third ore crusher to be installed at Chile's Chuquicamata copper mine. The proposed approach determines which …
We present a methodology for addressing the problem of deciding the location of a third ore crusher to be installed at Chile's Chuquica-mata mine, the largest open pit copper …
In this case the total material tonne-kilometres for the pit excavation will vary depending on whether you are using a backhoe or shovel.
Exploration methods are used to find, and assess the quality of mineral deposits, prior to mining. Generally a number of explorative techniques are used, and the results are then compared to see if a location seems suitable for mining. Remote sensing is the term used to gain information from a distance.
We present a methodology for addressing the problem of deciding the location of a third ore crusher to be installed at Chile's Chuquica-mata mine, the largest open pit copper mine in the world. This ap-proach evaluates a complex trade-o between minimizing operational cost and assuring production goal when the probability of equipment failure is …
The process of selecting open pit mining equipment is generally first to select suitable shovel equipment and supporting transportation equipment, then choose perforation equipment, and then select auxiliary equipment after the leading equipment is properly matched.
Open-pit mining, or surface mining, is a fascinating process of extracting minerals from the earth's surface. It is one of the most common methods used for mining, and it has been in use for centuries. But what exactly is it, and how does it work? In this blog post, we will take a closer look at open-pit mining, starting with an overview of the …
An approach to determine the location of an in pit crusher in open pit mines. In Proceedings of the 23rd International Mining Congress and Exhibition of Turkey, IMCET …
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 …
Facility location models are rarely used in the mining sector, but these models may be used for solving the in-pit crusher location problem.
Primary crusher is the workhorse that takes blast feed sizes and turns them into smaller sizes that are manageable for other site components—the belts, the screens, and eventually any secondary crushers—on the road to a finished product. All components at a crushing site depend on the primary crusher functioning properly, which is why …
The location of the mining: Different geographical locations may require different types of equipment to deal with different types of terrain and weather conditions.
In-Pit Crushing and Conveying (IPCC) systems are receiving more attention today due to current characteristics of open-pit mining operations and what is expected to occur in the future. Today, it has become more necessary than ever to reduce the cost of truck haulage, which accounts for roughly half the operating costs of mining operation. …

Determination of the optimum in-pit crusher location in open-pit mining under production and operating cost uncertainties
Ore is removed from a series of benches which are linked to the top of the pit by a 40 metre wide trench road. Each truck transports around 290 tonnes of excavated soil and ore to the top of the pit where it is stockpiled or sent to the primary crusher. The first ore from Oyu Tolgoi was mined at the open pit in April 2012.
