What are the pros and cons of subsurface mining? - QuoraAdvantages 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.subsurface mining drawbacks,Subsurface Mining and its Environmental Impacts by Cayla Heath .Oct 23, 2013 . Subsurface Mining and its Environmental Impacts Environmental Impacts - Acid drainage from the equipment - Toxic water end up in groundwater. - Abandoned mining sites can continue polluting groundwater after the mining has ceased. -Water must be pumped out of the mine during the mining process.
What are some of the advantages and disadvantages of subsurface .Subsurface mining is less disruptive to the environment that strip mining, however the danger to the miners is greater.subsurface mining drawbacks,Extraction and Processing of Minerals & the Environmental Impacts .To remove these minerals from the ground, subsurface mining is used. In subsurface mining, a long tunnel is created either horizontally or vertically. The tunnel walls are reinforced with wood and ventilation shafts are created to provide air to the miners underground. The minerals themselves are removed a number of.John Frank
By Alecia M. Spooner. Surface mining techniques don't work for extracting all valuable geologic resources. Diamonds and most metal ores, including gold, require extensive subsurface mines to access the rocks with these resources in them. Subsurface mines are probably what you envision when you think of mining:.
May 2, 2014 . Although there are opponents and proponents of underground mining, the disadvantages include destruction of land, surface subsidence, abandoned shafts, extensive surface spoil heaps, mine explosions, collapses and flooding. That doesn't incorporate the costly price tag that comes with underground.
Surface mines offer advantages and disadvantages when compared to underground mining. Amongst the advantages are that it is cheaper, can recover more of the resource (usually up to within the mining excavation), is safer and can use larger-scale mining equipment offering higher production rates.
Disadvantages: It is harder than surface mining and it also costs more money and takes more time Advantages: Leads to more minerals and ore, also creates less pollution.
Subsurface mining is less disruptive to the environment that strip mining, however the danger to the miners is greater.
This pretty much sums up the comparison of surface vs. underground mining. But is it that simple? . This historical event highlights the difference between two techniques of mining which are used even today - surface and subsurface mining. Let us compare and . The benefits and drawbacks of underground mining are:
Processing of ore from a lode mine, whether it is a surface or subsurface mine, requires that the rock ore be crushed and pulverized before extraction of the valuable minerals begins. After lode ore is crushed, recovery of the valuable minerals is done by one, or a combination of several, mechanical and chemical techniques.
Subsurface mining: Commonly used for zinc, lead, nickel, tin, gold, copper, diamonds, phosphate, salt, coal and uranium. Is used when the resources occurs in concentrated pockets deep underground. The most dangerous form of mining, consists on deep excavation. Networks of tunnels are dug or blasted out to follow.

Though there are obvious workplace hazards associated with working in a coal mine, these are not the only risks associated with mining activities. Simply living within proximity of a mine can actually cause a variety of health concerns, and both types of mining (deep and surface) pose their own set of problems.

Jul 1, 2016 . When coal mines move in, whole communities are forced off their land by expanding mines, coal fires, subsidence, and overused and contaminated water supplies. Mines are quick to dig up and destroy forests and soils. But once the coal is gone, the problems they leave behind, like acid mine drainage,.
Apr 24, 2012 . Like mining asteroids, getting to Mars is a long-term, lofty goal; so long as there is money to be made from developing the technology to reach that goal, these private space enterprises have a fighting chance of getting there. So Planetary Resources' premise isn't unreasonable, but there are many cons to.

Negatives. HUGE footprint; Waste rock piles can be enormous. Waste rock may be uneconomic to effectively mine, but once exposed to the atmosphere, they become hazardous to the environment; Remediation is extremely costly and time consuming. Groundwater restoration can be extremely costly. Mine workers' health.
Acid mine drainage (AMD) has the potential to be one of the most serious environmental problems caused by uranium mining in the Commonwealth of ... mining; in particular, the effects of direct introduction of oxygen into the subsurface that can mobilize uranium and form acid mine drainage (as discussed previously), and.
In general, mines, as drained bedrock systems, have the investigational advantage that spontaneous fluid flow from drill holes made for ore exploration and evaluation is common. Thus, mines have provided an access to deep subsurface microbial ecosystems e.g., in Arctic Canada (Stotler et al., 2009; Onstott et al., 2009).
Feb 5, 2018 . Core sampling, technique used in underground or undersea exploration and prospecting. A core sample is a roughly cylindrical piece of subsurface material removed by a special drill and brought to the surface for examination. Such a sample is needed to ascertain bulk properties of underground rock,.
