Machine vision is the study of techniques to extract meaningful information from highdimensional images. One approach to machine vision makes use of a range of digital image processing techniques, such as filtering, thresholding, edge detection, segmentation, or colour analysis, in order to obtain relevant information from the image.
Methane Detection and Monitoring What is the health and safety problem? The use of machinemounted methane monitors is required by federal regulations to alert miners to the presence of potentially dangerous concentrations of methane while mining coal. The monitors must be permanently mounted on a mining machine to provide continuous readings of methane levels near a working face.
Considering that Huainan is an important coal producing area. the coalgangue and coal blocks used in the experiment were obtained from Huainan mining area [11], and 300 coal and gangues with similar sizes were selected for spectral image order to improve the accuracy of detection, not only the multispectral image data containing multiple coal blocks and gangue are collected ...
Industrialization has stimulated an increasing demand for coal resources. In this process, belt conveyors serve a crucial role in the coal industry [].However, belt conveyors are vulnerable to damages such as deviation, slipping, and tearing due to overload, lengthy transport distances, and foreign objects [].Realtime detection of large foreign objects on belt conveyors in coal mines and ...

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.
A proximity detection system includes machinemounted components and minerwearable components. Final § (b)(1) requires that a proximity detection system cause a machine, which is tramming from placetoplace or repositioning, to stop before contacting a miner except for a miner who is in the onboard operator's compartment.
A detector that can only reliably detect a 3 mm sphere is said to have a lower sensitivity than one that can reliably detect a 2 mm sphere. SENSOR The metal detector component that first reacts to the presence of metal by emitting a voltage signal. The sensor usually consist of one or more coils. TRAMP METAL Unwanted metal in the product stream.
The coal mine advanced detection method for the heading machine according to claim 1, wherein the piezoelectric ceramic is a polarized barium titanate piezoelectric ceramic, a polarization direction is a direction vertical to a combination surface of the first piezoelectric ceramic piece and the second piezoelectric ceramic piece, a certain ...
At present, the portable carrier catalytic methane detection and alarm instrument for coal mine generally has many problems, such as high power consumption, short standby time, low detection accuracy, few parameters and single function, which can not meet the rapid development needs of mine safety. In this paper, a low power portable laser methane detection and alarm instrument based on ...

Since the SEM uses an inverted logic (, coal detection occurs closer to 0 than 1), the logistic function in (6) serves as a complementary coal likelihood function: (6) L ¯ (w; c, a) = 1 1 + exp (− a (w − c)), a = log e (1 − ε) / ε min {c, 1 − c} Fixing ε at, SEM is left with only one free parameter c which represents the ...
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.
An industrial metal detector or metal detection inspection system inspects raw or processed foods or nonfood products and inspects pharmaceutical products for metal contamination and safely rejects contaminated product from the production line. Food processing companies use industrial metal detectors to comply with food safety standards, retailer codes of practice and legislation.
With results available in a matter of moments, handheld XRF analysers are one option for speeding up exploration and onsite analysis process. XRF is commonly used to map deposits of base and precious metals, as well as rare earth elements and iron ore. Also, XRF analysers are often configurable to maximise their effectiveness in identifying ...

Focusing on various problems in coal gangue detecting and recognising algorithms, such as limited receptive field, slow convergence rate and low accuracy of small particle recognition, this paper proposes a coal gangue detection and recognition algorithm based on deformable convolution YOLOv3 (DCNYOLOv3).
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 ...
