Research on coal gangue recognition method based on XBS-YOLOv5s

Measurement Science and Technology, 2023
Abstract Aiming at the problems of misdetection, omission and low recognition accuracy of coal gangue recognition due to the harsh environmental factors such as low illumination, motion blur and large quantities of coal gangue mixing in coal mines, a coal gangue recognition method based on XBS-YOLOv5s is proposed.

Coal-Gangue Acoustic Signal Recognition Based on Sparse Representation

Applied Mechanics and Materials, 2013
Our country has rich coal resources. Further research is great significant to realize the automation of top coal caving mining technology. This paper presents a new method based on sparse representation for coal and gangue signal recognition. To solve the mining noise problem, the wavelet analysis is used to filter and de-noising. Sparse representation

Underground coal gangue recognition based on composite fusion of feature and decision

Measurement Science and Technology
Abstract The underground coal gangue separation and in-situ filling can reduce environmental pollution, promote the recycling of resources, and ensure the safe operation of mining. However, the harsh environment and abnormal working conditions are a significant challenge to the separation technology. Therefore, it is essential to develop
