Coal is mined in Appalachia by both surface and underground mining techniques. Surface coal mining methods in the steep terrain of the central Appalachian coalfields include mountaintop removal, contour, area and highwall mining. Coal mining operations are found in …
Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies.
Mining and burning coal for fuel is harmful to the environment; but, because coal is so abundant and cheap, many people are reluctant to give it up as a fuel source. Coal starts as peat, or sections of partially decomposed organic matter that accumulate on the earth's surface. Over millions of years, the peat is […]
Open pit mining disturbs larger areas than underground mining, and thus has larger visual and physical impacts. As the amount of waste rock in open pit mines is commonly two to three times the amount of ore produced, tremendous volumes of waste rock are removed from the pits and deposited in areas nearby.
The option which is not a consequence of moving from underground mining to surface mining should be C. mining collapses. This is because surface mining definitely changes the landscape and increases land degradation.

For surface effects to be registered as a result of mining operations, some form of underground collapse (in bulk, piecewise or monolithically) must precede such an effect. Therefore, the form of mining, degree and extent of activity coupled with geological factors play a role in this cause and effect action.
As a percentage of all coal mining, underground coal mining has been declining for many years, but in 2007 it still accounted for approximately 31 percent of coal mining, as compared with 69 percent surface mining.
Deep Coal Mining Community Health Risks The health outcomes associated with living in a deep coal mining community are various. Everything from increased rates of lung cancer, respiratory disease, and low birth weight can be linked to communities that are located near mining facilities.
Environmental cumulative effects of coal underground mining Unlike open mining, underground mining extracting coal resources through the wells, usually leads to land subsidence, water resources destruction, soil erosion, air pollution and biodiversity decrease.
The Harmful Effects of Mining. While mining provides us with the minerals we need, it is also very destructive because it disrupts the landscape both on the surface and underground.
Under the Act 54 amendments to BMSLCA, DEP is required to compile data and report findings regarding the effects of underground mining on land, structures and water resources. This review is done with assistance from professionals with appropriate expertise as stipulated by Act 54.
