Methods of Coal Mining And Investing In It

Coal has been made from plant and animal matter for millions of years, but unlike oil, coal is solid, so miners must go ashore to win. Coal seams are near the surface, which facilitates the extraction of this resource.

Opencast mining generally uses open-pit mining, which is generally more profitable than underground mining and requires fewer workers to produce the same amount of coal. In open pit mines, workers use huge earth moving equipment such as electric shovels or pull lines to remove the soil layers and rock strata that cover the bed of coal.

1. Coal mining method.

Mining is used for about 40% of global coal production

If coal deposits are close to the surface, it may be cheap to extract coal using this method. The different types of open pit mining are opencast mining, contour mining and mining.

Strip or surface extraction is more suitable for areas with flat terrain. Remove the charcoal by removing the soil in long cuts or strips above the carbon layer. When all the soil on the carbon layer is removed, the underlying carbon layer is exposed. The exposed carbon block can be drilled and dynamited. Once this strip is clear of coal, the tape extraction process is repeated with a new tape being made next to it.





The contour extraction method is the most commonly used technique in areas of rough or steep terrain. This method consists of removing the soil on the carbon layer following a pattern along the contours along a ridge or around a hill. This method can lead to significant landslide problems and erosion. To solve these problems, various methods have been developed to use newly reduced overheads to fill mining areas. Contour extraction is limited. If the operation reaches a predetermined compensation rate, it is not profitable to continue.

Coal mining at the summit of the mountain involves obtaining peaks to expose the coal seams and removing the associated mine overburden in nearby valleys and hole filling. This method combines surface extraction and contour belt methods.

Modern opencast mining processes recover a larger proportion of coal deposits than underground methods.
Underground mining is required if the coal seams are too deep. The main underground methods are Long wall, Continuous, Blast, Short wall and Retreat.

Long-term mining accounts for about 50% of underground production. He uses a sophisticated machine with a rotating drum that moves mechanically in a large layer of carbon. The elongated mining ensures a high production level with high safety. The sensors used in this extraction process help detect the amount of carbon remaining in the weld, while the robot controls improve the efficiency of the process.

Continuous mining is used for about 45% of underground coal production. It is used as a machine with a large rotating steel drum equipped with tungsten carbide teeth to scrape the carbon off the seam.

Mining in mining accounts for less than 5% of total underground production in the United States. UU Mining is an old practice that uses explosives such as dynamite to break the layer of coal. Then the broken coal is collected and loaded into wagons or load carriers and driven to a central loading area.

The short-wall extraction method is used for less than 1% of the deep-coal production. This method also uses a continuous suction machine with movable roof supports, similar to extraction with long pits.

The mining method uses carbon columns or ribs to support the mine roof. This method is one of the most dangerous extraction methods because it can not be predicted when the roof or roof will collapse and pinch or pinch the miners.

1. The coal industry and invest in it.

2.1. The story of the use of coal.

Large-scale mining was introduced in the 18th century

Coal was first used as a household fuel until the industrial revolution became an integral part of production for power generation, transportation, heating and molding. The appearance of large-scale mining was introduced in the 18th century, and the UK was the first country to successfully use advanced coal mining techniques, including underground mining and mining. ,

Initially, the coal was removed from the surface by various methods such as drift and well extraction. This has been done for centuries, and since demand was quite low, these dismantling processes were more than enough to meet market demand.

However, as the practical use of coal as a fuel fueled an industrial revolution, demand for coal increased sharply, leading to a significant shortage of coal production and gradually opening the door to new methods of coal mining. the earth

Coal is still a popular fuel for all purposes, as it is abundant and can produce more energy in the mass than other conventional solid fuels such as wood. This was important in terms of transportation, power generation and manufacturing processes, which allowed the industry to take up less space and increase productivity. The use of coal began to decline as soon as almost all processes used alternative energies such as oil and gas. However, coal is still a major fuel for manufacturing processes.

2.2 The process of coal mining.

Coal mining is a difficult and complex process

Coal is a natural resource, a fossil fuel produced by decades of destruction of plants and living organisms in the subsurface. Some are on the surface while other coal deposits are deep.

The mining or extraction of coal takes place in two different processes: surface extraction and deep excavation. The excavation method depends on several factors, such as: The depth of the underground coal bed, geological factors such as soil composition, topography, climate, resources available on site, etc.

Opencast mining is used to scrape off coal that is available on the surface or at depths of a few meters. This may even include mountains of coal that are extracted with explosives and blown into the mountains. Then the shattered coal is collected and processed.

Underground mining works use underground tunnels that are either built or excavated to reach the center of the coal deposit, from where the coal is dug and brought to the surface. This is possibly the most dangerous excavation method, in which the life of all miners is constantly in danger.

2.3 Invest in coal.

Investing in coal is a safe bet

There are still significant coal deposits in the world, and because of its popularity, coal continues to be used as fuel for the manufacturing process. Any investment you make in any type of industry or manufacturing process will ultimately depend on the amount of production that the industry can provide, the use of any form of fuel and, in most cases, coal. ,

It could be argued that the use of coal leads to less pollution and less stringent hygiene standards for coal miners. This may have been the case in the past few years. However, new coal mining companies are taking steps to minimize the environmental aspects of mining and coal utilization while providing a better working environment and a benefit package for their employees. If you find a mining company that promises all that and works lawfully, you can count on your investment in coal.
