Calculation of water storage space and changes in underground coal mine reservoirs

In view of the limited limited water storage space and unstable structure in traditional caving mining, and the invisibility of goaf leads to the difficulty of accurate calculation of water storage space, this paper proposes a comprehensive technical method for the digitization o...

Analysis of mid-infrared spectral characteristics and recognition models of coal with different particle sizes

As a core energy source, the accurate identification of coal particle size is a critical part in the quality control of raw coal mining, separation and processing, storage and transportation, and quality upgrading. The differences in physical and chemical properties of coal with...
