Influence of coal gangue mulching with various thicknesses
The coal gangue having undergone no weathering was taken from the gangue dump. Meanwhile, near the gangue dump, a soil profile about 500 cm high formed due to the continuous excavation of theTailing product T r1 exhibited the highest ash content of 67.75%, implying that a large number of coal and gangue combinations existed in the coal flotation tailings, which were difficult to separate directly. After two flotation separations, the low-ash products with a yield of 19.28% and an ash content of less than 10% could be recovered.Associations of Gangue Minerals in Coal Flotation Tailing

Preparation of coal gangue ceramsite high-strength
Coal gangue (CG) is a type of industrial solid waste produced by the process of coal excavation and separation 1,2,3. Generally, one ton of CG is discarded for every 10 tons of produced coal 4,5 .Among coal mining-related wastes, coal gangue (CG) is the heterogeneous waste generated during the mineral processing or coal washing phase of coal mining. A thorough understanding of environmental concerns associated with the current model of CG utilization and potential future application is gaining paramount importance.The Sustainable Utilization of Coal Gangue in Geotechnical

Coal gangue detection and recognition algorithm based on
4.1 Design and implementation of coal gangue detection and recognition device. This study proposes an method for coal gangue detection and recognition on the basis of the DCN-YOLOv3 algorithm. Firstly, the method collects real-time video images of a conveyor belt operation through an industrial camera erected perpendicular to the To improve the detection of coal and gangue under complex conditions, we proposed a cascade network that consists of detector and discriminator. Employing the idea of combining traditional computer vision with deep learning, the multi-channel feature fusion layer was designed in the discriminator. The convolutional neural network (CNN) in theCascade network for detection of coal and gangue in the

An exploratory study on strategic metal recovery of coal gangue
Coal gangue is a resource that is often improperly managed, especially during the current strategic metal element shortage. The ash content of this coal gangue is 84.98%, meaning it is not suitable for use as fuel because of its low calorific value. Furthermore, the common specific surface area (16.364 cm 3 g −1) and pore volumeCoal gangue has become one of the industrial wastes with the largest annual discharge and accumulated stock in China. The disorderly accumulation of coal gangue not only occupies a large amount of land resources and causes natural disasters, but also pollutes the surrounding ecological environment, which in turn affects human Review of Coal Gangue Characteristics and Ecological

Coal-gangue recognition via multi-branch convolutional
Traditional coal-gangue recognition methods usually do not consider the impact of equipment noise, which severely limits its adaptability and recognition accuracy. This paper mainly studies theHowever, coal gangue (CG) is a solid waste discharged during coal mining and preparation, and the weight of CG accounts for approximately 15%–20% of the production of coal (Chen et al., 2008). With the continuous mining of coal, the total accumulated amount of CG in China has reached more than 7 billion tons, increasing Influence of thermally activated coal gangue powder on the

In mining, gangue (pronounced "gang") is the commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore deposit. It is thus distinct from overburden, which is the waste rock or materials overlying an ore or mineral body that are displaced during mining without being processed. 以上来源于:.Gangue refers to waste rock discharged during coal mine construction, coal mining, etc 1.Excessive accumulation of coal gangue will cause serious environmental problems 2,3,4.At present, the coalResidual deformation of coal gangue subgrade filler under

Controlling water temperature for efficient coal/gangue recognition
1. Introduction. Coal is the most important fossil fuel resource in China [1, 2].In 2020, China's coal production reaches 3.9 billion tons. Gangue is black-gray solid wastes that were mixed in coal, which play a detrimental role during production and reduce the economic value of coal [3], especially when mining thick seams (e.g. 10 m–20 m)
