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

Recognition of Coal and Gangue Based on X-Ray

Applied Mechanics and Materials, 2013
In this paper,a recognition method of coal and gangue based on x-ray is studied. With the different density , the coal and gangue on a belt can be detected by x-ray. After penetrated by x-ray, with the acquisition of ray signal and image analysis, the gangue can be accurately distinguished from the coal.

Research on recognition of coal and gangue based on image processing

World Journal of Engineering, 2015
In order to avoid the waste of water resources and environmental pollution caused by separating coal and gangue in the traditional methods, a novel method based on image processing is proposed in this paper. Firstly the image of coal or gangue is preprocessed.
