Coal Sizer is a professional coal crushing equipment, mainly used for crushing raw coal, coal gangue, coal coke and other materials. According to the crushing degree, coal sizers can be divided into onestage crusher and twostage crusher. Our coal sizers has the characteristics of wear resistance, impact resistance, stable operation, convenient maintenance and so on.
With the aim of solving the problem of coal congestion caused by big coal blocks in underground mine scraper conveyors, in this paper we proposed the use of a YOLOBS (YOLOBig Size) algorithm to detect the abnormal phenomenon of coal blocks on scraper conveyors.
Machine vision Damage detection 1. Introduction As one of the most important transportation equipment in the field of continuous conveyance of bulk materials, belt conveyor is developing towards the direction of longdistance, high belt speed, large volume, and intelligence [1].
SEC1000C model splittype metal detectors can eliminate signal interference furthest from products themselves (like ore, coal, chemical, renewable resources, waste etc.) and conveyor belt itself by using DSP digital intelligent technology, at the same time, ensuring conveyor and products (like ore, coal, chemical, renewable resources, waste etc.) to pass detector, also can achieve perfect ...
The belt conveyor is the most commonly used conveying equipment in the coal mining industry. As the core part of the conveyor, the belt is vulnerable to various failures, such as scratches, cracks, wear and tear. Inspection and defect detection is essential for conveyor belts, both in academic research and industrial applications. In this paper, we discuss existing techniques used in ...

It is a small start, and a somewhat larger plant in Texas is in the works, but this is the typical scale of a DAC plant today. "We have a climate change problem and it's caused by an excess of CO2 ...
The analysis of coal quality detection system. analyzer is composed of . ... PLC and touch screen, etc.), etc. machine, weighing module, electrical module, Detection
View object in our online collection. First, a little background history. Canaries were used in mines from the late 1800s to detect gases, such as carbon monoxide. The gas is deadly to humans and canaries alike in large quantities, but canaries are much more sensitive to small amounts of the gas, and so will react more quickly than humans.
Detection of coal fire is the premise to make firefighting plan and is of great significance for their efficient and economical extinguishing (Shao et al. 2017; Shao et al. 2014; Shao et al. 2016). Therefore, before attempting to extinguish coal fire, its location and underground extent should be determined as precisely as possible. Coal fire ...
In the field of coal exploration, according to the different spectral characteristics of coal and other objects on the ground, the coal mining area is analyzed by remote sensing technology to obtain the coal mine distribution, coal composition and the ecological environment around the coal mine.
Combination of metal detector and electromagnetic separator protects coal crushers and prevents breakdowns. Machine type: SZEB160009 overband electromagnetic separator Parameters: dimensions 4,900 × 2,440 × 1,160 mm, weight 11,350 kg, belt width 1,600 mm,
1 Citation Explore all metrics Cite this article Abstract Large foreign object transporting by coal mine conveyor belt may lead to production safety hazards. To reduce safety accidents during coal mining, a large foreign object detection method based on machine vision is proposed in this paper.
Support vector machine (SVM) was used to identify the coal types. The number of flame features used to build the SVM model was reduced from 20 to 12 by combining the methods of ReliefF and SVM ...
The gases are the present in the underground mines are flammable gas (CH4), Noxious gases (NO2, NO3, N2O5), Carbon Monoxide (CO), Carbon Dioxide (CO2). Hydrogen Sulphide (H2S), Sulphur Dioxide (SO2). The permissible limit set for these gases are as follows. Underground air should not have more than % CO2 or other noxious gases.

Mineral Rare Earth Elements Analyzers. Portable Xray fluorescence (XRF) technology can be used in a wide range of mineralogical and geological exploration markets, one of which is the mining of Rare Earth Elements (REEs). REEs are defined as the 15 lanthanides plus scandium (Sc) and yttrium (Y), and they are critical components in consumer ...
In coal production, the raw coal contains a large amount of gangue, which affects the quality of coal and pollutes the environment. Separating coal and gangue can improve coal quality, save energy, and reduce consumption and make rational use of resources. The separated gangue can also be reused. Robots with computer vision technology have become current research hotspots due to simple ...
The MINER Act of 2006 mandates wireless twoway communication systems in underground coal mines in the USA. In addition, in 2015, the Mine Safety and Health Administration (MSHA) issued a final rule that requires operators of underground coal mines to equip placechanging continuous mining machines (CMMs) with proximity detection systems (PDSs) that generally use electronic sensors on both ...
