Coal extraction
At Breyten Colliery Opencast Mine we use a range of powerful machines that helps us drive the process of coal extraction from exposed coal seams.
Machinery used in the coal extraction process include excavators, which remove overburden and unearth coal, while massive haul trucks transport the extracted materials. Front-end loaders assist in coal loading, while bulldozers prepare the terrain and drill rigs create blast holes for explosives to expose surveyed land for coal seams.
Crushing and processing equipment ensure coal is ready for transport and use. Water management equipment controls dust, tailings, and flooding. These machines, operated by skilled professionals, are the driving force behind the productivity and success of opencast coal mining operations, helping to meet energy demands while adhering to safety and environmental standards.
Frequently Asked Questions
What are the main methods to extract coal during coal mining?
There are two main methods of coal extraction: surface mining and underground mining.
-
Surface mining: Surface mining is the most common method of coal extraction. It is used to extract coal that is located near the surface of the ground. Surface mining involves using machines to remove the topsoil and overburden (rock and soil that covers the coal seam) to expose the coal seam. The coal is then removed using a variety of methods, including shovels, excavators, and conveyor belts.
-
Underground mining: Underground mining is used to extract coal that is located below the surface of the ground. Underground mining is a more dangerous and difficult process than surface mining. It involves using tunnels and shafts to access the coal seam. The coal is then removed using a variety of methods, including cutting machines, explosives, and conveyor belts.
What are the environmental impact of coal mining operations?
- Air pollution: Coal mining can release dust and other pollutants into the air. These pollutants can contribute to respiratory problems, heart disease, and cancer.
- Water pollution: Coal mining can contaminate water supplies with heavy metals and other pollutants. This can make water unsafe to drink or use for bathing.
- Land disturbance: Coal mining can damage land and disrupt ecosystems. This can make it difficult for plants and animals to live in the area.
What are the benefits of using coal?
Coal is a valuable source of energy, and it is used to generate electricity, produce steel, and heat homes and businesses.
