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 ...
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.
Mining of coal around the world is being continued to meet the evergrowing energy demand. Mining involves extensive clearing of ground cover, change in physiography, generation of massive solid and liquid wastes to reach coal and thereby alters ecology and environment of the mining site as well as the neighboring areas. Depending on the nature, origin and seam arrangement of a coal reserve ...
Toxic metals are typically present in "free" quantities in biological systems due to the presence of tiny biological ligands that can form mixed aquabioligand complexes with metals. In vivo complex formation reactions often take the form of ligand or metal exchange reactions involving hazardous metals and chelating agents [17].The equilibrium constant and complex formation are extremely ...
Borehole temperature measurements were the primary tool used to detect underground coal fires until 1963, when the United States began to use thermal remote sensing (TIR) techniques to detect and monitor coal fires [6,15,19]. Since then, TIR has proven to be a reliable and useful tool for identifying and monitoring underground coal fires.
Subtle variations in the measured properties can be used to determine the abundance and composition of key minerals at Earth's surface. For example, specific spectral absorption features and ...
Panel A coal mining block that generally comprises one operating unit. Panic bar A switch, in the shape of a bar, used to cut off power at the machine in case of an emergency. Parting (1) A small joint in coal or rock; (2) a layer of rock in a coal seam; (3) a side track or turnout in a haulage road.
Prevention and control of coal spontaneous combustion are key to coal mining and storage. Existing technologies for the detection of coal spontaneous combustion have limitations, but coal spontaneous combustion creates some serious disasters in areas of the world where coal mining and/or storage exists. New technologies to detect coal spontaneous combustion are urgently needed to reduce the ...
In geotechnical engineering, a nuclear densometer or soil density gauge is a field instrument used to determine the density of a compacted material. The device uses the interaction of gamma radiation with matter to measure density, either through direct transmission or the "backscatter" method. The device determines the density of material by ...
If you are new to the mining industry, chances are that you want to know which types of machines are commonly used. The following are the top 6 types of machines used in the mining industry. Mining Drills; The most common type of machine that is used in the mining industry is a mining drill. It is crucial for underground mining operations.
2. Materials and Substrate subtraction. To be able to detect soil organisms against a background of varied substrates, we simulated recovery ofH. bacteriophora entomopathogenic nematode (EPN) infective juveniles (IJs) from sand and muck soil solutions. The sand was autoclaved playground sand (Lowes) and the soil, high organic matter muck soil collected from Oswego, NY and autoclaved.
The coal delivered from the mine that reports to the coal preparation plant is called runofmine, or ROM, coal. This is the raw material for the CPP, and consists of coal, rocks, middlings, minerals and contamination. Contamination is usually introduced by the mining process and may include machine parts, used consumables and parts of ground ...
The main goal of the work was to determine whether a radarbased system could be used to detect coalrock interfaces in order to establish a suitable mining horizon within the coal seam.
Other researchers [83] [84][85][86][87] used ML models to segment coal types (classified by different fixed carbon content in coal) [83], geology type (bituminous coal, lignite, sandstone, soil ...
Further, a change detection technique is used to detect active, new, and closed surface coal mines in a region. Detected closed mines are further analysed to evaluate reclamation of that region.
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. An adaptive weighted multiscale Retinex (MSR) image enhancement algorithm is proposed to improve the captured image quality of the belt conveyor line. An ...
All of this data is analyzed by computer program algorithms, which in turn is analyzed by engineers or trained vibration analysts to determine the health of the machine and identify possible impending problems like looseness, unbalance, misalignment, lubrication issues and more. Vibration analysis can detect problems such as: Imbalance.
This method was specifically developed for determining the nitrogen contents in organic and inorganic substances. In today's world, Kjeldahl nitrogen determinations are used on several samples like wastewater, soil, fertilizers, meat, feed, grain, and many other substances. The method is also used for estimating the protein content in foods.
API is proactively integrating modern technology and developing standards to advance safe and responsible natural gas and oil production in addition to complying with regulations as part of a shared goal of zero incidents and reduced emissions. This is illustrated by two recently published API standards related to leak detection in liquid pipelines intended to help operators reduce the risk of ...
In the search for new sources of oil and natural gas, energy companies are guided by evidence gleaned from huge arrays of data gathered by sending sound waves deep into the ground. At MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL), experts in machine learning and computer vision are developing mathematical tools that ...
Second, the cutoffs used for our thermal scores to detect COVID19 and lung injury were optimized for this specific study cohort, and need to be adjusted in future multicenter trials with larger ...
FS21 Advantages. Affordability: Five to ten times more affordable than any competing device. Ease of use: Installation takes 30 seconds and a single battery charge lasts a full year. Accuracy: Measures air temperature, air humidity, soil moisture (10, 20 and 30cm) and soil temperature (10, 20cm) Key Advantages. Farm21.
Swetha et al. (Citation 2020) developed an RGB imaging method that can predict soil texture using a deep learning algorithm [convolutional neural network (CNN) model].The development of RGBbased soil imaging is in the beginning stage, but in the future, it could help to further improve soil nutrient status management using HSI and sensorbased ...
