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.It is widely used in coal mine underground equipment positioning and information transmission. In view of the above problems, this research uses the WLR-5A mining unmanned wheeled chassis experimental platform; uses two UWB receivers to infer the position and yaw information of the vehicle in the underground roadway through the Energies Special Issue : Intelligent Coal Mining Technology

Characteristics of coal resources in China and statistical
2.2 Coal resources mining characteristics. With the active promotion of China's carbon peaking and carbon neutralization work, China's energy supply has achieved remarkable results and production has grown steadily (Zhang et al 2022; Li 2021).As shown in Fig. 2, the raw coal production of China was 4.13 billion tons in 2021, up 5.7% year-on Room-and-pillar 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 room-and-pillar technique. Contour mining is similar to longwall mining, but it follows the contour of a seam.Beginner's Guide to Coal Mining An Underground Miner
