Various Applications Of Electronics In The Mining Industry

Some of the common types of electronics used in the mining industry include switchgear, distribution boxes, power centres, tracking systems for vehicles as well as people, radio systems, capacitor boxes and a lot of other stuff. Take the example of deep coal mining. In this type of mining coal as well as other materials are extracted from mines that are several hundred metres deep down

Armoured Face Conveyor

Coal is actually cut in front of the AFC, so a lot of the coal initially sits on the base of the cut section and does not fall directly onto the AFC. This coal is lifted onto the AFC as it is pushed forward. Because it is necessary to cut the maximum amount of coal on each web, it is important that this coal is able to be cleaned up as the AFC advances and not left on the floor, thereby

Blasting Techniques Used in Underground and Opencast

If tubs arc used for transport of coal, track can be laid right up to the face in the absence of coal cutting machines. 5. When working a seam over a caved area, the floor is irregular and coal cutting machines cannot be used. Solid blasting offers definite advantages in such cases and in other cases where floor may be irregular for some other reasons. For Deg. 1 gassy mines at least 284 m 3

Title: Coal Mining 1 Coal Mining 2 Coal Mining. The goal of coal mining is to economically remove coal from the ground. Coal is valued for its energy content, and since the 1880s is 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

Longwall Mining Equipment

plows to be used for any coal hardness and with higher efficiency than other longwall extraction methods in low and medium heights. This is supported by greater installed power than any other manufacturer – up to 1 600 KW (2,160 hp) with the GH1600. Any incremental plowing as offered by means that the plow cuts a precisely defined depth, regardless of coal hardness, seam structure and

Electrical safety in opencast mining

The big excavators used for open-cast mining have lots of different drives. They use both medium voltage engines and low voltage drives. The large drives, in particular, are normally supplied by ungrounded systems. These are monitored by an ISOMETER with a coupling device. For smaller drives, we recommend monitoring with RCMS residual current monitoring systems or ISOMETER

New technologies reduce environmental impacts of coal

Circulating fluidised-bed (CFB) technology is an existing available technology, already being used to burn coal and other fuels to produce energy in a clean, environmentally responsible way. CFB is a clean coal combustion platform with a unique low temperature combustion process that can burn both traditional fuels and carbon-neutral fuels, including biomass, waste coals, tires, and processed

Coal Mining South Africa

As the coal seams here are buried too deep beneath the ground for opencast mining, they are deep mined using a room and pillar technique. The mine site is divided into a series of rooms that are cut into the coal bed using continuous miners; these machines extract the coal whilst digging a hole at the same time and can mine as much as five tons of coal a minute. Once the coal is removed, the

Highwall Mining System

Highwall mining is a proven primary method for mining coal from outcropping horizontal seams. In this method of mining, an unmanned continuous miner is driven underground and operated in front of the highwall. The highwall mining machine stands on the pit floor or on a bench, directly in front of the exposed seam and makes long parallel rectangular drives into the coal seam. A remote-operated
