Coal Exploration and Mining

In the second part, two basic methods of extracting coal, i.e. surface mining and underground mining, are introduced. Firstly, two main methods—strip mining and open-pit mining—of surface mining are discussed. In underground mining, room and pillar, shortwall, and .

Coal mining - Wikipedia

Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is a 'pit', and ...

Top of Coal - Mining3

Accurately detecting the top of a coal seam before blasting is a key factor to effectual coal recovery. Depending on local site geology and seam conditions, up to 12% of the marketable coal resource is estimated to be unrecoverable due to coal loss and dilution during the mining process. During the extraction stage, a significant percentage of overall coal loss is attributable to blast damage ...

Detecting Water and Coal Ore on a Conveyor .

To detect the difference between water and coal (solids), we used a very low frequency 10kHz acoustic transducer, mounted on a 60 degree angle aimed at the trough (bottom) of the conveyor belt. The 10kHz transducer is so powerful that the signal bounces and reflects off the top of the water showing a "longer distance", but will detect coal, iron ore, even fines, or other solids,that can be ...

Although many geophysical techniques have been used to detect the disaster geological anomalous body in the Huaibei coal mine company, there are still many mining disasters happening. The main reason is that the coal seam is rich of water in Huaibei coal areas. If the ground water connects with tunnels, it will cause the flood to collapse the coal seam.

Coal mining - Wikipedia

Coal that occurs at depths of 55 to 90 m (180 to 300 ft) are usually deep mined, but in some cases surface mining techniques can be used. For example, some western U.S. coal that occur at depths in excess of 60 m (200 ft) are mined by the open pit methods, due to thickness of the seam 20–25 metres (60–90 feet).

Coal Geology | Geoscience Australia

Coal is mined by both surface or 'opencut' (or opencast) and underground or 'deep' mining methods, depending on the local geology of the deposit. Underground mining currently accounts for about 60 per cent of world coal production but around 80 per cent of Australia's coal is produced from opencut mines.

Where does the methane in a coal mine come from? Methane is formed as a byproduct of the coal formation. The methane that is adsorbed in the coal is released as the coal is mined or it migrates from surrounding sources above or below the coal seam through fractures created by the coal extraction process. How is methane detected and controlled? Large fans circulate air in mines to provide ...
