Ecological Effects of Subsurface Mining dummies

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: 

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.

What are the advantages and disadvantages of subsurface mining

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.

3 Technologies in Exploration, Mining, and Processing

The life cycle of mining begins with exploration, continues through production, and ends with closure and postmining land use. New technologies can benefit the mining industry and consumers in all stages of this life cycle. This report does not include downstream processing, such as smelting of mineral concentrates or 

Underground v.s. Surface Coal Mines: Is Deep Drilling Worth the

May 2, 2014 There are many advantages as well as disadvantages to both methods, including financial and environmental reasoning. You decide which is best for you. Underground mining. Underground or "deep" mining consist mostly of two methods roomandpillar and longwall mining. In roomandpillar, coal 

Uses and Advantages of Geothermal Resources in Mining

subsurface temperature of Nevada and California is very high. Besides these regions are rich in minerals which are water soluble. When such minerals are subjected to high pressure and temperature mineral becomes soluble and we get a fluid which has all these water soluble minerals. GEOTHERMAL AND MINING 

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

Air Compressors for the Mining Industry Mattei

Due to the inherent dangers of the industry, the equipment utilized in all aspects of mining must be of the highest quality, in terms of both performance and reliability. In surface and subsurface mines, industrial air compressors are used as a viable source of electricity for powering drilling and piling machinery, pneumatic 

Longwall mining Wikipedia

In addition to productivity gains, automating longwall equipment leads to safety benefits. The coalface is a hazardous area because methane and carbon monoxide are present, while the area is hot and humid since water is sprayed over the face to minimize the likelihood of sparks occurring when the shearer picks strike 

What are some of the most important disadvantages and advantages

Underground Mining is a method of Mining, where the mineral is extracted without removing the top soil and rocks. In this way we do not disturb the surface feature such as forest, agriculture land, rivers and residential areas. The major disadvant

What are the advantages and disadvantages of subsurface mining

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 rock salt were inadvertently discovered at a well drilled for oil and gas. rock mining (room and pillar) and solution mining (well injection) methods have been in use continuously for over one hundred .. public transportation in the Northeast would literally freeze in a standstill without the benefits of salt during.

The Actual Difference Between Surface and Underground Mining

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 Advantages and Disadvantages. The pros and cons of 

Potential Environmental Effects of Uranium Mining, Processing, and

Many of the same potential impacts to groundwater quality described for drilling apply to underground exploration and 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 the artificial connection of separate

Surface Mining Sustainable Development & Environmental

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 largerscale mining equipment offering higher production rates.
