Coal is South Africa's major primary energy source and plays a significant role in supplying the chemicals and steelmaking industries The benefits of coal production are relevant in the light of South Africa's development priorities of job creation and economic growth Even so primary metal production and coal based power generation industries through their operations and activities pose a significant and.
Beneficiation of Fine Coal Using the Air Table D P Patil and B K Parekh Center for Applied Energy Research University of Kentucky 2540 Research Park Drive Lexington KY 40511 Abstract The increased mechanization in the underground coal mining industry has increased the volume of fine size coal and waste (refuse) in the mined coal.
The transfer of the raw coal its beneficiation and handling generates coal dust while open burning of coal for steam or other usage releases gaseous discharge to the surface atmosphere The movement of coal from the pit head to the loading or consumption points in open leaky trucks or open wagons also adds coal dust to the environment all along the route.
Studies have looked at the health effects in coal mining communities and found that community members have a 70 greater risk of developing kidney disease and a 64 greater risk of developing chronic obstructive pulmonary disease (COPD) such as emphysema They are also 30 likely to report high blood pressure (hypertension) 7 2.
Jul 18 2018 It is found in steel plants that 1 increase of ash in coking coal results in the following deteriorating effects (Kumar D 1982) Increases the slag volume involving expenses for slag dumping Decreases production of blast furnace by about 3.
The coal being mined is of high vitrinite content and is commonly known as “hard coking coal” The value of coking coal is significantly higher than steam coal It is therefore important to optimize the plant yield and recover the maximum percentage from coal mined.
Coal mining is a development activity which is bound to damage the natural ecosystem by all its activities direct and ancillary starting from land acquisition to coal beneficiation and use of the products.
Jul 18 2018 The basic purpose of beneficiation is to reduce the ash forming impurities from raw coal so that better coal with less ash content can be produced If these ash forming constituents are not removed and coal is directly charged to the coke ovens the ash content in coke will increase and subsequently slag will be produced in the blast furnace thereby lowering the efficiency of the blast furnace.
Jul 09 2017 Burning of washed coal significantly reduces smoke (greenhouse gases) dust and ash emissions from the plant It also improves the plant load factor and plant availability and reduces specific coal consumption and wear and tear of the coal handling plant and other equipment.
Coal mining during the Tenth Plan period Open cast coal mining is being used extensively because of its cost effectiveness and productivity despite large scale land disturbance Underground mining has considerably less impact but causes enough damage through subsidence e g.
Impact of Coal Mining on Land Irrespective of the type of mining used for extracting coal mining invariably results in enormous land disturbance than 80 000 ha of land in India are affected by various mining activities It is estimated that a total land of 539 sqkm is disturbed through opencast.
Feb 01 2019 Environmental implication of coal mining Mining of coal generates waste rock (WRs) that are major potential sources of Acid mine drainage (AMD) (discharges carrying high loads of sulphide oxidation products and associated metals) AMD usually contains toxic heavy metals and it is a critical environmental pollution problem in mines.

Perhaps the most significant impact of a mining project is its effects on water quality and availability of water resources within the project area Key questions are whether surface and groundwater supplies will remain fit for human consumption and whether the quality of surface waters in the project area will remain adequate to support native aquatic life and terrestrial wildlife.
Starting from its excavation to loading and unloading coal produces dusts and radiation which have a direct negative impact on the ecology biodiversity and health of the surrounding communities 17 During drilling blasting sizing and transportation the release of total suspended particulate (TSP) matter and inhalable particulate matter (PM 10) is the reason of air pollution in and around the mining zone 18 To.
Key impacts of surface mining are typically massive disturbances of large areas of land and possible disruption of surface and groundwater patterns In some surface mines the generation of acid mine drainage (AMD) is a major problem Other significant impacts include fugitive dust and disposal of overburden waste rock.
A cheap but dirty fuel source We have started to look for other sources of renewable energy but to date coal is still the number one energy source Coal provides 40 of the world’s electricity and it produces 39 of global Carbon Dioxide emissions.
Impacts may continue long after mining ceases Table 1 presents the levels of liquid effluents solid waste and dust generated by the major mining techniques Beneficiation plants produce large volumes of tailings and solid wastes Storage and handling of coal generates dust at rates of as much as 3 kilograms per metric ton (kg t) of coal mined.
The negative effects of coal mining cannot be disputed Destruction of Landscapes and Habitats Strip mining also known as surface mining involves the stripping away of earth and rocks to reach the coal underneath If a mountain happens to be standing in the way of a coal seam within it will be blasted or levelled effectively leaving a.
Raw coal may be sold as mined or may be processed in a beneficiation washing plant to remove noncombustible materials (up to 45 reduction in ash content) and inorganic sulfur (up to 25 reduction) Coal beneficiation is based on wet physical processes such as gravity separation and flotation Beneficiation produces.
