Coal mining
Coal mining is the process of extracting coal from the ground or from a mine. 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 called a 'pit'37.1 An Explosion in a Coal MineMining Machinery an overview ScienceDirect Topics

Deployment of Continuous Miner in under Ground Coal Mine: A
India is the second-largest coal producer globally, where 93.7% of coal is produced from opencast mining [], and the rest of the coal is produced from underground coal mining.With the high rate of extraction from opencast mining and the increase in the number of new open cast mining fields, it is essential to depend on underground coal in Mine gas, fires, dust and coal burst are major issues in the coal mining industry with severe consequences.

Longwall mining
Longwall mining is a form of underground coal mining where a long wall of coal is mined in a single slice (typically 0.6–6.0 m (2 ft 0 in 19 ft 8 in) thick). The section of rock that is being mined, known as the longwall panel, is typically 3–4 km (1.9–2.5 mi) long, but can be up to 7.5 km (4.7 mi) long and 250–400 m (820–1,310 ftMining electric locomotive is mainly used for long-distance transportation of underground transportation roadway and ground. It is equivalent to the electric locomotive head in railway transportation. It drives the train composed of mine car or man car on the track to complete the transportation of coal, gangue, materials, equipment, and personnel.Mining Locomotives JXSC Machine

Classification of clustered microseismic events in a coal mine
In this paper, the feasibility of applying machine learning to classifying seismic events distributed around a major dyke and the longwall face in an underground coal mine was investigated. Four classifiers, i.e. random forest (RF), support vector machine (SVM), DCNN, and residual neural network (ResNN), were tested based on a Coal miners use it when the coal is deeper than 200 feet underneath the surface. The coal may be as far as 1000 feet deep. In this type of mining, coal miners use elevators to go down deep mine shafts and then travel on small trains through tunnels to gain access to the coal. Surface mining consists of open-pit, contour, mountain-top and How Many Jobs Are in Coal Mining? (Including Types of Jobs)

Research and practice of intelligent coal mine technology systems
3.1.2 Construction of intelligent coal mine knowledge map. Through the establishment of information entities, the mapping from the physical space to the digital space is realized. This mapping includes not only physical entities (e.g., coal mining machines, hydraulic supports, and tunneling machines), but also time entities (e.g., roof Photo about Fisheye view of mining machine drilling organ, modern machinery in coal mine, tunnel drilling machine used in Alps (Alpina).

Development of a Digital Model of Mining Face of Coal Mine
Abstract The structure and the digital model of the mining face of coal mine are presented. The digital model contains the parameters of the coal bed, the technical parameters of the used mining machinery, and the economical indicators. The digital model can be applied to support decision-making in increasing the productivity of The equipment needed for coal mining includes: cutting machines, conveyor belts, hoists, hydraulic supports, crushers, ventilation systems, pumps, cutters and other specialized tools.

Dynamic simulation of an opencast coal mine: a case study
The intent of the mine plan was to use one dedicated excavator, and to use the FEL as a back-up machine, and not in parallel with the excavator. There were instances when the mine used both excavators and the FEL, but only achieved production of 1502 t/h. The use of both excavators and the FEL in parallel on coaling activities was Block diagram of algorithm of the electrical complex of a coal mine model.
