Research and practice of intelligent coal mine technology
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 9.2.2. Intelligent interaction mode of HCPS of mining equipment. In the area of coal mining, the production and living system compose of engineering staff and simple physical tools/devices are called the Coal-mining Human Physical System (Cm-HPS). The essence of the Cm-HPS development is that humans continue to innovate and apply Production process management for intelligent coal mining

(PDF) Availability analysis of selected mining machinery
In order to optimize the use of machines in coal mining enterprises, it is necessary to make proper selection of the machines for the operating conditions and keep them in good technical conditionA water truck is necessary on most mining sites because of the various safety and health risks that respirable dust particles pose. Excessive dust can lead to serious health concerns for miners, such as pneumoconiosis (CWP), a potentially disabling lung disease. In Queensland, coal mining regulations limit workers’ exposure to respirable dust.Top 6 mining equipment & machinery Open cut mining machinery

Coal mining and transportation U.S. Energy Information
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.12.9: Mining. Mining is the extraction of valuable minerals or other geological materials from the earth from an orebody, lode, vein, seam, or reef, which forms the mineralized package of economic interest to the miner.

Coal Mine Safety Evaluation Based on Machine Learning: A
The four elements (man, machine, environment, and management) in the coal mine and their synthesis are calculated and analyzed by using the Matlab tool and the BP neural network program. The predicted value of the personnel intrinsic safety value is (0.86–0.85). The intrinsic safety value of the equipment is (0.93, 0.95).A coal mine in the central district of Botswana is experiencing premature failure of conical picks which mine 150-350 tons of coal/ pick rather than 400 tons/pick specification.a Cutting action of continuous miner machine; b

Energies Free Full-Text A Review of Intelligent Unmanned Mining
Intelligent unmanned mining is a key process in coal mine production, which has direct impact on the production safety, coal output, economic benefits and social benefits of coal mine enterprises. With the rapid development and popularization of 5G+ intelligent mines and coal mine intelligent equipment in China, the intelligentization of Coal miners use large machines to remove coal from the earth. Many U.S. coal deposits, called coal beds or seams, are near the earth's surface, while others are deep underground.Modern mining methods allow coal miners to easily reach most of the nation's coal reserves and to produce about three times more coal in one hour than in 1978.Coal Energy Kids: U.S. Energy Information Administration
