For many years, machines have been used to continuously excavate soft minerals in underground mines. In some cases, this includes the soft, or weak, rocks that surround the valuable mineral being extracted. Coal is probably the most common example. Much of the mine development tunnelling in underground coal mines is done in coal.
FUCHENG. Jinan Fucheng Hydraulic Equipment Co., Ltd. was established in 2002, formerly known as Shandong Fucheng Hydraulic Equipment. As an underground mining equipment supplier, it is one of the most famous underground mining equipment manufacturers in China. Fucheng has advanced RD technology, a mature technical team, and rich experience ...
Page 725 dragline at Turkish Coal Association Yenikoy Open Pit Coal Mine, Milas. A dragline excavator is a piece of heavy equipment used in civil engineering and surface mining . Draglines fall into two broad categories: those that are based on standard, lifting cranes, and the heavy units which have to be built onsite.
'Rathole' mining was used to extract coal from narrow and deep mines in Meghalaya. In January 2019, some 15 miners lost their lives when they were trapped for more than a month in one such mine.
Coal Mining and Combustion in the Coal Waste Dumps of Poland. Justyna Ciesielczuk, in Coal and Peat Fires: A Global Perspective, 2015. Summary. Coal mine activity in Poland has provided millions of tons of coal waste every year, which were used for terrain leveling or were deposited on the dumps. Some part of them have been reclaimed as a filling material.
Longwall Mining of Coal. Longwall mining of coal is a high production and high productivity method, employing sophisticated electrical, mechanical, and hydraulic systems, as well as computerbased monitoring and control systems. Most modern (coal) longwall faces are semiautomated. It is noteworthy that longwall operations in trona mines utilize essentially the same equipment and processes ...
Roomandpillar mines allow for continuous mining. This process uses robotic equipment to move vast amounts of coal quickly. Longwall mining mines a single coal seam in one single tunnel, rather than the many rooms used in the roomandpillar technique. Contour mining is similar to longwall mining, but it follows the contour of a seam.
The term coal quality is used to distinguish the range of different commercial steam coals that are produced directly by mining or are produced by coal cleaning. 3 Generally, coal quality for steam coals (, coal used for electricity generation) refers to differences in heating value and sulfur content, although other characteristics such ...
Coal Mining Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. Surface Mining If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.
The multibilliondollar global mining equipment market is growing at a rapid rate. As in an expected compound annual growth rate (CAGR) of % through 2027. Technology is, in part, driving sales. Although machines are getting smarter, the types of equipment used in mining have largely remained the same. In this article we discuss common ...
Coal miners use two primary methods to remove coal. Surface mining is often used when coal is less than 200 feet underground. In surface mining, large machines remove the topsoil and layers of rock known as overburden to expose coal seams. Mountaintop removal is a form of surface mining where the tops of mountains are removed to access coal seams.

Layers of rock and dirt above and between the coal seams are removed. Coal seams are removed with excess soil and rock placed in an adjacent valley. Large scale earth moving equipment is used to excavate and remove coal from lower layers. The equipment used depends on the method and scale of the surface mining method being employed.
Longwall shearers The coal is cut from the coal face by a machine called the shearer (power loader). This machine can weigh 75120 tonnes typically and comprises a main body, housing the electrical functions, the tractive motive units to move the shearer along the coalface and pumping units (to power both hydraulic and water functions).
