Open pit mining method is one of the surface mining methods that has a traditional cone-shaped excavation and is usually employed to exploit a near-surface, nonselective and low-grade zones deposits. It often results in high productivity and requires large capital investments, low operating costs, and good safety conditions. The main …
In this method, large-scale excavation machinery, such as excavators and haul trucks, is used to remove the overburden (surface material) and expose the ore deposit. The ore is then extracted and transported to the processing plant. b. Underground Mining: Underground mining is employed when the iron ore deposit is located at …
Careful integration of geology, ore reserve, mining and processing systems has led to major improvements in performance and optimizing cost options in solving capacity and …
This document has been written to introduce new mining engineers (and experienced mining engineers new to planning or particular types of block models) to mineral …

In block caving, a large section of ore is initially undercut by drilling and blasting, creating a large unsupported roof that will start to collapse under its own weight and instability, The broken ore then breaks apart and falls into a series of pre-constructed funnels, or drawbells, and access tunnels developed underneath the caving rock ...
Illegal mining is a significant issue for the industry so preventing illegal or unregulated mining operations will help ensure that all mining is bound by the same environmental standards and ensure accountability. Economical viability. Mine development starts when a deposit is discovered and continues through to the start of construction.

world. The model determined which section of the ore to mine, and when to start mining them so as to minimize deviation from the planned production quantities, while adhering to the geotechnical and machine availability constraints. Sarin et al. scheduled a coal mining operation (2005) with the objective of net present value maximization.

Top hammer longhole drill rigs are ideal for mining operations where the highest priority is ore recovery and minimizing the contamination of rock fragments. Like its surface mining counterpart, this drill contains a piston-powered hammer that impacts the drill in order to shatter the rock before using compressed air to disperse the debris.
These waste materials have led to the generation of acid mine drainage (AMD) (Gardi c et al., 2015;Korac & Kamberovi c, 2007) which has contaminated the waters of the Timok river system (Adamovi c ...

"ArcelorMittal India (AMIPL), the holding company of ArcelorMittal has commenced mining operations at Thakurani iron ore mine. The block, with estimated reserves of around 179 MT, will make a valuable contribution to AM/NS India's long-term raw material requirements," a statement issued by AMNS India said.
The exploitation of open pit deposits usually takes place through a series of mining phases, commonly known as pushbacks. In open pit metalliferous mining, each pushback considers the extraction of one or more benches simultaneously in a process where the core operational tasks include: drilling, blasting, loading and hauling.
For the underground operator, dilution is often synonymous with over-break, which mining operations struggle to control. However, there are many additional factors impacting dilution which may surpass the importance of over- ... Example 4: Internal Dilution within the ore Envelope A block model should include internal dilution even if the drill ...

A mining operation has identified an area where the ore is rich enough to excavate. The excavation proceeds in distinct blocks from the surface downward. The problem is sketched in its two-dimensional form with numbered blocks in the following figure. Because of the angle of slip, block 5 cannot be mined unless both blocks 1 and 2 are mined.
Mineral and Mining sector, being one of the core sectors of economy, provides basic raw materials to many important industries like power generation (thermal), iron and steel, cement, petroleum and natural gas, petro-chemicals, fertilisers, precious and semi-precious metals/stones, electrical and electronics equipment, and glass and …
