The Advantages of Open Pit Mining Sciencing

Open pit mining does offer some advantages over traditional deep shaft mining. Pit mining is more cost effective than shaft mining because more ore can be extracted and more quickly. The working conditions are safer for the miners because there is no risk of cave in or toxic gas. Open pit mining

Pros and Cons of Strip Mining APECSEC

For those who are unfamiliar, strip mining is a form of surface mining that focuses on the collection of tar sand and coal, which both rest somewhat close to Earth's surface. Those who support strip mining point to the increased ease of access and all of its attendant benefits. Detractors point to the controversies surrounding this method.

What are the pros and cons of subsurface mining? Quora

Advantages of underground mining: *less surface disturbance *less environmental disturbance *less waste mined per tonne of ore *ability to mine resources that are not economic as a surface mine *cheaper to set up mine development for deep ore depo

9 Most Valid Advantages and Disadvantages of Coal –

First off, coal extraction is not difficult, whether it is mined on the surface or underground. Between opencast mining (surface) and deep mining (underground), the former recovers 90% or more of the coal compared to the latter, which basically means that miners do not have to go deep in the earth all the time.

Surface mining SlideShare

SURFACE MINING • Surface mining is done by removing (stripping) surface vegetation, dirt, and, if necessary, layers of bedrock in order to reach buried ore deposits (or) surface mining is the process of extraction of minerals by removal of overburden . • Overburden is the rock or waste material which is lying on the mineral to be owned .

What are the advantages of opencast mining? Quora

Opencast mining has several advantages compared to underground mining, these are: * Opencast allows for high tonnages to be moved hence economies scale * Safe as workers are not working under disturbed roof * Opencast trucks have higher payloa

What are the Advantages and Disadvantages of underground

2009412&ensp·&enspAdvantages. Underground mining (as compared to open pit exploitation) allows a mine operation to be largely 'hidden' having only adits or headframes protruding above the surface. This enables the land above the zone of mining to be reclaimed for other uses, after the mining has ceased, so much easier than in the case of an open pit.

Slope Mining, Shaft Mining, Drift Mining, Mining

Slope Mining With fast progress of modern industry, the demand for products manufactured from metal ores has gone up literally. In order to meet this demand, the awareness of uninterrupted mining, which can sharply elevate stope productivity and cut mining costs, has become a big trend in the development of mining techniques in underground mines.

Underground Mining for Meeting Environmental Concerns –

Underground mining can be considered to be more acceptable than surface mining from environmental and social perspectives since, it often has a smaller footprint than an openpit of comparable capacity. The main advantage of underground mining compared to surface mining is that in general only the ore is extracted and waste rock is left behind.

Surface Mining, Industry of Metals, Minerals, Precious

Surface mining is a form of mining in which the soil and the rock covering the mineral deposits are removed. It is the other way of underground mining, in which the overlying rock is left behind, and the required mineral deposits are removed through shafts or tunnels.. Surface mining is basically employed when deposits of commercially viable minerals or rock are found closer to the surface
