A review of coal gangue identification research—application to China’s top coal release process

Environmental Science and Pollution Research, 2022
Top coal caving is a process for the rational extraction of large amounts of coal resources. However, this process readily causes release of excessive amounts of gangue during the coal release process. The conventional technique, which involves visual inspection, is not only labor-intensive but also can introduce inaccuracies.

Coal and gangue identification method based on the intensity image of lidar and DenseNet

Applied Optics, 2021
Coal and gangue (rock) identification is the essential process in a coal preparation plant. In an actual coal preparation plant, the existing classification methods have many disadvantages in safety and identification rate. We utilized the echo intensity image (EII) of lidar for coal and gangue identification for the first time, to ...
