Coal mining
Coal extraction methods vary depending on whether the mine is an underground mine or a surface (also called open cast) mine. Additionally, coal seam thickness and geology are factors in the selection of a mining method. The most economical method of coal extraction for surface mines is the electric shovel or drag line. The most economical form of underground mining is the loOpencast coal mining is a large-scale activity that seriously and rapidly impacts the ecological environment.

Life cycle assessment of opencast coal mine production: a case
The Yimin opencast coal mine was selected to conduct a case study. The production of 100 tons of coal was used as the functional unit to evaluate the environmental risks in the The coal measures are generally shallow, largely unfaulted and lightly inclined, making their exploitation suitable for opencast and mechanised mining.

Remote Sensing Free Full-Text Monitoring Extractive Activity
Mining developments in alpine coal mining areas result in slow or rapid ground subsidence, which can lead to melting and collapse of permafrost. This paper integrated unmanned aerial vehicle (UAV) images and satellite-based SAR interferometry images to monitor intensive surface mining subsidence during reclamation.

Impact of Open Cast Coal Mining on Air and Water Environment
High values of hardness of mine water reduces it's utility in domestic purposes. The article illustrates the quality of acidic and non acidic mine water and leachate characteristics of opencast coal mining OB dumps. Pollutants such as TSS, TDS, oil and grease and heavy metal are found in the coal mining waste effluents.The increasing trend of opencast coal mining in India tends to release huge amounts of dust. But there is no well-defined method of estimating dust emission due to different coal mining activities. This paper examines the sources of dust emission due to coal mining activities, and focuses on the quantification of dust emission with the Generation and Quantification of Hazardous Dusts from Coal Mining

Mining. In Australia, nearly 80% of coal is produced from open-cut mines, in contrast to the rest of the world where open-cut mining only accounts for 40% of coal production. Open-cut mining is possible because coal seams are close to the surface. Such mining is cheaper than underground mining and enables up to 90% recovery of the Trace element pollution of soils surrounding coal-mining areas affects the health of local communities. The increasing coal-mining and associated activities in the Raniganj basin (east India) have led to increased soil concentration of certain trace elements. To quantify the elevated trace element (TE) concentrations in the soil Trace element contamination in soils surrounding the open-cast coal

Open-Pit Mining Definition Anglo American
Open-pit mining, also known as opencast mining, is a surface mining technique that extracts minerals from an open pit in the ground. Open-pit mining is the most common method used throughout the world for mineral mining and does not require extractive methods or tunnels. This surface mining technique is used when mineral or ore deposits Also in Queensland, QCoal's Byerwen Coal Project commenced shipments of met coal in 2019. The opencast mine could reach a production rate of 10 Mtpa met coal in 2021 after significant site expansion. A third of the world’s more-advanced coal mining projects are located in Australia, mostly in Queensland, with total capacity of 38 Mtpa.Coal mining projects Coal 2020 Analysis IEA

How to optimize dust pollution control in opencast coal mines:
Some opencast coal mining enterprises are only interested in profits, lacking firm environmental protection awareness and social responsibility, which exacerbates the situation . As the most direct victims of coal mining dust pollution, residents in mining areas suffer greatly from illegal discharge of pollutants.12.10: Open-Pit Mining. Open-pit mining, or open-cast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow. This form of mining differs from extractive methods that require tunneling into the earth, such as long wall mining. Open-pit mines are used when deposits of12.10: Open-Pit Mining Geosciences LibreTexts

Along with changes in land-use, open cast coal mining also changes the topography along with the drainage pattern of the region. It was observed that majority of the increase in opencast mining area (53%) and built-up area (85%) took place between 2003 and 2010 for the present study area (BCCL Annual Report 2013–2014).Dumpers or Tippers 9. Drag Line 10. Road Grader 11. Rock Drills.
