What is open-pit mining? Open-pit mining, also known as opencast mining, is a surface mining technique that extracts minerals from an open pit in the ground. Open-pit mining is the most common method used throughout the world for mineral mining and does not require extractive methods or tunnels. What are the mining machines called?
The modified Machine Repair Model is first applied to a virtual open pit mine case study. The results compare favourably to output from other estimation models using the same input parameters for the virtual mine. The modified Machine Repair Model is further applied to an existing open pit coal operation, the Kwagga Section of Optimum Colliery ...

The effective operating time (EOT) of the equipment in an open pit mine determines the capacity of the mine. Clearly, EOT is only a part of the total calendar time, which also includes various down times or non-productive times, caused by different factors. Therefore, it is important to analyze the components of calendar time.

This study aimed to develop and assess the feasibility of different machine learning algorithms for predicting ore production in open-pit mines based on a truck-haulage system with the support of the Internet of Things (IoT). Six machine learning algorithms, namely the random forest (RF), support vector machine (SVM), multi-layer perceptron neural …
EPSA's first involvement in the mining industry was in 1976, when we were enlisted by an open-pit mine to provide our expertise. From the outset, our focus has been on meticulously aligning machinery and engineering with the unique demands and timelines of …
Kennecott Copper Mine, located in Bingham Canyon, is the largest open-pit mine in North America. It is known as the "Biggest Pit in the World," because it is the largest man-made excavation in the world. It covers about twenty-seven …
In mining, deposits are divided into blocks, forming the basis for open-pit mine planning, covering production and haulage route planning. Current studies often stage optimization and lack the consideration of road capacity, leading to suboptimal solutions. A novel approach integrates production scheduling and haulage route planning through a bilevel …
Different types of drills are used depending on the nature of the material being drilled. Bulldozers are powerful machines equipped with a broad, flat blade at the front, used for pushing large quantities of soil, sand, or rubble during construction or mining activities. Draglines are used in open-pit mining for removing overburden.
When the front end loader is used as the main mining and loading equipment in the open pit mine, its efficiency depends on the layout of the front end loader and the automobile and the dimension of the stope working face. (1) Front End Loader and Automobile Layout. ① Front end loader is inclined to the automobile. As shown in Figure 1(a), the ...

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.
In open pit mining, extreme dust concentrations are largely diluted by atmospheric dispersion and winds, thereby mitigating the level of exposure for workers to some extent. ... At first, dust accumulation may mean just having a dirty windshield or some peeling paint, but problems caused to machines by dust accumulation can significantly reduce ...
Open pit mining - also called open cut mining or open cast mining - is a surface mining technique used to extract rocks and minerals. It requires large-scale equipment, including shovels and drills. Motor graders also play a role, maintaining haulage roads so that both equipment and mined material can be transported to and from the mines.

The value of productivity gains from an effective shift-change will dwarf the added personnel costs of an additional 15 minutes per shift. This way, the on-coming operators can be waiting for the truck or shovel to park and begin their shift. Remember: we always want the person waiting on the machine, not the machine waiting on the person.
