We can use some of the safety technologies developed for mining in other industries, such as constructing deep underground subway tunnels, water pipes, and other structures. Some of the heavy equipment developed for mining may also be used in deep excavation projects, such as when we build canals or dig foundations for large buildings.
Advantages of Underground Mining are: * It allows minerals to be extracted from deep underground * It doesn''t create a mess like open cut or surface mining * Does not affect the physical
The advantages of surface mining are: * It is cheaper to extract the ore or metal than underground mining * Less chance of workers dying from toxic fumes, therefore it is safer unlike underground
#0183;#32;Historically speaking, underground mining not only saves the mining areas original form but also gives the mining company higher revenues. According to, longwall mining, a type of underground mining that utilizes a longwall shearer, accounts for 50 percent of coal mines in the world and is much safer than other methods of coal mining.
Underground mines are the alternative to surface mines. Surface mines excavate from the top down, a method that can become inefficient at depths greater than about 200 feet (60 meters) [sources: Illinois Coal Association, De Beers].Undergrounds coal mines can drive 2,500 feet (750 meters) into the Earth and other types even deeper uranium mines can reach 6,500 feet, or 2 kilometers.
#0183;#32;Explanation: Shallow mineral or coal deposits can be economically mined by openpit or strip mines. However, with deeper mineral or coal deposits it becomes very costly to remove a great deal of overburden in these kinds of settings. So, in these cases underground mining is more cost effective. The downside is that human health and safety are at
Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the surface. There are a number of reasons for this, not the least of which is that the size of underground mining equipmentbecause of ground conditions, ore body geometry, and other factorsis much smaller than in the open pit.
1. Underground Mining Methods Classification of Underground Mining Methods Mineral production in which all extracting operations are conducted beneath the ground surface is termed underground mining. Underground mining methods are usually employed when the depth of the deposit and/or the waste to ore ratio (stripping ratio) are
What are the advantages of underground mining Advantages of Underground Mining are: It allows minerals to be extracted from deep underground; It doesn''t create a mess like open cut or surface mining; Does...
ADVANTAGES A) Underground mining (as compared to open pit exploitation) allows a mine operation to be largely having only Adits or head frames protruding above the surface. This enables the land above the zone of mining to be reclaimed for other uses, after mining has ceased.
Underground mining equipment, as the name implies, is used in mining underground and drilling deep into the earth. It needs more money to drill, keep miners safe and install safetycentric equipment. A great deal of preparatory work is required to successfully conduct drilling operations and to establish effective ventilation methods.
Advantages and Disadvantages of Mining Mining . Dec 07, 2019 In mining there is a lot of disadvantages and advantages. The main disadvantage is the electricity cost. There are a lot of rich miners who find a country where the cost of electricity is low. The advantage is you earn coins much faster in mining resulting in profit. Send Inquiry
advantage underground mining. Sep 06 2016 #183; What are some of the most important disadvantages and advantages of underground mining 1 Very less land acquisition and RR problem 2 The soil and agriculture land is destroyed in opencast Mining Not in the case of UG Mining 3 No destruction
#0183;#32;Advantages of underground mining: (1) Less loss of land (2) Minimum dust pollution (3) Minimum noise pollution (4) Lack of nearsurface deposits may make underground mining the only method. (5) Unfavorable geologic structure may require that a surface mine move underground
Mining Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on
Mining involves the extraction of valuable minerals from the earth surface. Mining can either be surface mining or subsurface (underground) mining. Mining not only beneficial to the surrounding community and public in general, but it can also pose a lot of risks to the surrounding community. Lets look at the pros and cons of mining []
