Surface Mining. Author: Alan Cluett ~ Environmental Consultant, Holcim South Africa ( Article Type: Explanation) Mining, by its very nature, is not sustainable into the future. Through the process of mining, finite natural resources, in the form of minerals, are extracted from the Earth's crust, beneficiated and consumed by our society.
drawbacks of jaw crusher disadvantages subsurface mining bnsdav. What are the advantages and disadvantages of surface . Advantages of surface mining include economic and financial benefits for miners and communities and a safer alternative to pit mining, but its disadvantages include.
Disadvantages: Surface mining is very dangerous. Advantages: Subsurface mining is safer Subsurface mining is cheaper, Subsurface mining is faster 60% of the mining in the US is Subsurface mining.
Open-pit mining is much safer than shaft mining. In underground mining, the threat of a cave-in or release of toxic gas is a constant concern. When shaft mining was the most common method of ore extraction, thousands died in cave-ins, gas events and accidents involving equipment. In 1907 alone, more than 3,200 deaths related to mining occurred.

If we are able to weight the pros and cons of mountaintop removal for coal mining, then we can determine if this is a practice we should continue. There are definite cost-savings advantages that can be seen, but this comes at the expense of local geological changes. ...
Subsurface mining is the removal of deposits from the earth by drilling underneath layers of rock and dirt. These deposits are difficult to reach from the surface and require the drilling of vertical or horizontal shafts for access.
Surface mining reclamation restores vegetation, soil stability, and proper water conditions after mining. Each site will be completed differently depending on the future use and reclamation law. However, the work completed prevents future environmental degradation and prepares the site for its future use.
Apr 06, 2010· US Mining Trends 11. Pros and Cons Surface Subsurface -disturbs large area -produces large amounts of spoil -relatively safe -cheaper -more efficient -disturbs much smaller surface area -spoil often left in mine -dangerous -expensive -less efficient 12.
Although both methods have their benefits and drawbacks, underground drilling may just be the cost worthy selection for you Mining for coal depends on many variables. The geology and environmental aspects play a vital role, but depth and quality of the seam is what brings home the bacon. Depending on where the seam (profitable bed of coal) is located, extracting this black gold can require a ...
Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.
It is large enough for men and machinery to move about, is cost efficient and safe compared to open shaft mining. Cons: Leads to habitat loss, creates large holes in the ground and those holes allow water to drain into them where they could become acidic.
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...
Environmental Impacts Laws - Details about how the topsoil will be affected and how it will be replaced must be stated before mining begins. - All affected water must be processed and cleaned before leaving the mining site. - Procedures for public notice, public participation and
