Strip mining is done only when the ore body is in close proximity to the surface. Open-pit mining – Open-pit mining is the method in which minerals or rocks are extracted from the Earth via an open pit or borrow. Mountaintop removal mining – Mountaintop removal mining (MTR) is done by mining coal seams underneath mountaintops.

Open-Pit Mining Methods

Open-Pit Mining Methods. 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.

Although open pit mining (link to mining solution page) contributes about 85% of all mineral mining, it is one of the most environmentally taxing. About 73% of extracted rock goes to waste. Meanwhile, underground mining wastes only 7% of the extracted rock but is more expensive (Hartmann and Mutmansky, 2002).

Due to being the safest layers to mine where all ores exist in reasonable quantities (especially diamond), layer 10 to 15 are usually considered the best area in which to start mining. The single best layer for mining is highly debated and is not agreed on.

Grade control is used to define the ore grades and blocks in the pit. For an exploration program, the quality of the samples is imperative for mine planning and blasting—the samples must be reliably accurate. RC drilling is the superior method used for grade control in open pit mining operations because:

It is suitable for ore bodies with a mining depth of 30-50m and an inclination angle of less than 5-10°. External waste dump is the dump outside the open-pit mine boundary for stacking stripped materials, or other sites selected for stacking waste rock and soil. This article will discuss the open-pit mine waste dump from the following aspects:

Surface mine means an excavation in the earth conducted above ground (open-pit mine) for the purpose of opening-up, proving or pro d u c i n g any mineral from a natural deposit.

The two foremost kinds of surface mining are open-pit mining and strip mining. Open pit mining involves digging out rocks to form an open pit or borrow pit, from which resources are then extracted. An open pit mine generally has stepped sides to minimize the risks associated with collapse and a large ramp for mining equipment.

Open pit mining refers to mining directly on the ground surface, thereby producing an open pit. This method is practical and cost-effective when the uranium ore is located near the surface (e.g., within 100 m). Underground mining and ISL methods may be considered for sites that have uranium ores at deeper depths.

In designing an open pit mine to optimise an orebody, numerous considerations are made. These include geological, geotechnical, mining method and equipment selection considerations. To achieve the optimisation of an orebody depends on sound mine design principles and adherence to the mining sequence with employee's

A surface mine contains pits with mineral endowed rock (or ore). We extract ore that lies within the upper layer of the earth, from surface mines (Fricke, 2006) . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface mining, including open-pit, stripping, dredging and mountain-top removal.
