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 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.

An Image Recognition Approach for Coal and Gangue Used in Pick-Up Robot

2018 IEEE International Conference on Real-time Computing and Robotics (RCAR), 2018
Picking gangue from raw coal is a crucial step of coal production. Due to the potential for replacing manual workers, the study of pick-up robot is attracting much interest. Pick-up robots usually work in fixed working areas where the types of coals and gangues are unitary.

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
