Open-pit mining, or open-cast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow. This form of mining differs from extractive methods that require tunneling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful minerals or

Open-Pit Mining Method and Process Epiroc

Open-pit mining technology. 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.

Optimized design of drilling and blasting operations in open pit

2018.11.1 1. Introduction. Mining activity is mostly represented by these four main operations: drilling, blasting, loading and hauling. For a proper mine planning and design, all of these operations need to be carefully planned in such a manner that can prevent extra loads such as operating costs, environmental footprints, etc. Amongst these operations,

Blastability and Ore Grade Assessment from Drill Monitoring for Open

2021.4.17 Blasting performance is influenced by mechanical and structural properties of the rock, on one side, and blast design parameters on the other. This paper describes a new methodology to assess rock mass quality from drill-monitoring data to guide blasting in open pit operations. Principal component analysis has been used to combine

Improving productivity at an open-pit mine through enhanced

Productivity is improved by increasing the ratio of output to input. In an operating open-pit mine, improving the productivity of heavy mining equipment (HME) enables the unit cost of production to be reduced. To optimize HME productivity, the Kolomela open-pit iron ore mine transitioned to an enhanced short-term mine planning (STMP) process ...

Mine Planning and Optimisation Techniques Applied in an Iron

2020.1.1 The rock mass transportation volume with the use of motor transport at the iron ore industry is more than 350 million tons per year, or 27% of the total volume of open pit mines in the industry.

A Mine-to-Crusher Model to Minimize Costs at a Truckless Open-Pit Iron

2022.8.18 Innovation has an important role in improving the productivity, safety and sustainability of mining operations. Historically, ore transport was done by diesel trucks, but with the commitment to reduce CO2 emissions and increase mine safety, mining companies have invested in innovative, more sustainable ore transport technologies. The innovative

Mining - Open pit mine ArcelorMittal

Most iron ore mining operations use the ‘open pit’ method, where miners drill into the rock and blast the ore-bearing material loose with explosives. Huge excavators are then used to gather the loosened ore. To mine metallurgical coal, which will later be turned into coke, it’s usually necessary to sink vertical mine shafts to access coal which is deposited in layers
