Characterization of the gas explosion under continuous disturbance by coal gangue in a coal mine gob

Gas explosions in coal mine gobs caused by the spontaneous combustion of coal usually result in serious threat to energy security. The main feature is that the explosion flame is initially disturbed by the coal gangue. To recognize the characteristics of

A coal-gangue optimization identification method

Gong-kuang zidonghua, 2020
Aiming at problem that target detection of coal-gangue image is not accurate due to wear of conveyor belt, which affects identification accuracy of coal-gangue, a coal-gangue optimization identification method is proposed. After pre-processing of collected images such as cutting, denoising and grayscale, the trained cornernet-squeeze deep learning ...
