Coal-gangue image classification method

Gong-kuang zidonghua, 2020
For problems that traditional coal-gangue separation methods such as manual separation method, mechanical wet-separation method, γ-ray separation method and so on could not give consideration to high efficiency, safety and easy operation, a coal-gangue image classification method based on machine vision was proposed.

Study on axial compressive behavior and mesoscopic structural evolution of FRP confined coal gangue concrete.

PLoS ONE
To address the environmental hazards caused by coal gangue waste, coal gangue concrete (CGC) has been proposed as a solution. However, due to its porosity and low strength, CGC faces numerous challenges in practical applications.

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 ...

Advances in research on technologies for large-scale coal gangue utilization for green mine construction

Meitian dizhi yu kantan
BackgroundThe coal gangue, a solid waste, features high production and a continuous increase in the amount piled in China. The long-term piling up of coal gangue will cause the waste of land resources and environmental pollution in mining areas.

Comprehensive treatment status and zero carbon treatment exploration of coal gangue hill in China

Meikuang Anquan
In the process of mining coal resources, a large amount of coal gangue, fly ash and other by-products are produced, which cause a series of secondary disasters and environmental problems. In order to solve a series of disasters caused by the accumulation
