has resulted in some negative environmental effects. Coal mining can result in the destruction of land which is strip mined, the production of overburden waste and slag heaps, mine fires, and the occasional collapse of underground mines. At the power plant, sulfur dioxide, NO, and particulate matter arex released into the air.
Coal balls tend to be brown in color and the coal-ball limestone includes many fragments of coal and coal spar. Coal balls are extremely rare in the Eastern Kentucky Coal Field, but are not uncommon in the Springfield (W. Ky. No. 9) and Herrin (W. Ky. No. 11) coal beds in the Western Kentucky Coal Field.
Although, the presence of carbon, hydrogen and sulfur in coal facilitates the energy generation in coal combustion, some pollutants including COx, SOx, NOx, particulate matter (PM) and heavy metals are accumulated in air and water and lead to severe environmental and health impacts as a result of leaching, volatilization, melting, decomposition, oxidation, hydration and other chemical reactions.
Positive and Negative Effects of Coal. Coal is one of the major source of energy and is formed by the prolonged decaying of the organic material for million of years. It is one of the major source of energy and is a non- renewable resource of energy.
Mining Regulations. REGULATION OF COAL MINING Ohio''s first state law regulating coal mining, the Strip Coal Mining Act, became effective in 1947. This law required Ohio mine operators to have a state-issued license and, to ensure that reclamation would be performed, to pay a .
Coal power can create high levels of radiation. Breathing in coal dust or ash is also known to be a cause for lung cancer development over time. A coal mining disease called "Black Lung" can impact total lung capacity, is incurable, and is often fatal. People with Black Lung literally die of suffocation.
Apr 25, 2017· Environmental Impact Of The Coal Industry On Air. The coal industry, which includes coal mining and coal generated electric plants, is responsible for emitting at least 20 toxic chemicals into the air. These chemicals include: mercury, arsenic, lead, selenium, zinc, nickel, and radium (to name a few).
Full Answer. Limestone mining can pollute water and create sinkholes. When limestone dissolves while it''s still in the ground, caves and gullies form, a natural phenomenon known as karst. Although this doesn''t hurt the environment in its natural form, once the limestone is mined out, sinkholes can form and disrupt underground waterways.
This mineral is a basic building block of the construction industry and the chief material from which aggregate, cement, lime, and building stone are made. For the purposes of this report, limestone will be used as a sample for crushed rock. One product of limestone mining is lime.
Coincidentally, caves are adjacent to huge reserves of coal and limestone. The Meghalaya Pollution Control Board says it is studying the effects of coal mines on the environment and the caves. "Once the mining policy comes into effect, every coal miner will be required to treat the mine water," says D Hooroo, member secretary of the board.
Effects on pH. Organisms which cause acid mine drainage can thrive in waters with pH very close to zero. Negative pH occurs when water evaporates from already acidic pools thereby increasing the concentration of hydrogen ions  . About half of the coal mine discharges in Pennsylvania have pH under 5.
Longer term problems, or legacy problems, are impacts of coal mining that are still being dealt with today from mines long closed. Legacy problems refer to impacts like climate change; but also, being specific to coal mining one of the most prevalent legacy problems is acid mine drainage. Acid mine drainage is a condition where, as the name suggests, the water is made acidic.

Sep 28, 2010· • Dust deposits in the lungs, damages lung tissue, and causes scarring • Disease development typically takes over 10 years of dust exposure • Silicosis results from inhalation of respirable silica dust • Coal workers'' pneumoconiosis (black lung disease) results from inhalation of respirable coal dust.
Pollutes the air with dust. This affects wildlife and creates poor air quality in the area. Mountaintop removal, where tops of hills and mountains are removed to reveal coal.
Sep 11, 2012· And since more has to be burned, it produces more pollution. Power plants use a mix of out-of-state coal and Texas lignite in order to meet clean air rules. Located in Limestone and Leon Counties in East Texas, the Limestone power plant is owned by NRG. It was opened in the 1980''s.
communities have been particularly exposed to the detrimental effects of contamination arising from mining and its effects on public health, agriculture and the environment. In addition, the legacy of mining has left thousands of sites in Africa contaminated by mining and associated mine dumps such as tailings and slag material.

Impact of mining on land environment gets reflected in land-use pattern of the respective area because the more the land gets exposed to erosion by loosing its green cover or by getting disturbed otherwise due to mining (excavation, overburden dumping etc.) and related activities, its water resources gets damaged, soils get
Oct 22, 2005· When the Xiaoqing coal seam was mined in the Wangfeng Mine, the protective layer was 22 m thick and the potentiometric pressure of the underlying limestone ranged from 13 to 18 kg/cm2. The calculated inrush coefficient was 0.8–1.4 kg/cm2/m, which was greater than the critical value of 0.8 kg/cm2/m in the mine.
