The concept of artificial intelligence (AI) was born in the mid-twentieth century to describe endeavours computer science focusing on simulation human learning. Since then, advances computing, data collection and storage have made AI an increasingly important area for researchers practitioners across a range disciplines business social sciences. Despite that, there appears be very few attempts at cataloging condensing prior research this area. As such, paper uses VOSViewer visualizer...
The presence of gas content in medium- and high-rank coal poses a threat to safety production. Safe extraction is based on correct understanding the pore structure coal. This work investigates characteristics evaluates their fractal structure. samples were collected from Huainan Coalfield Qinshui Coalfield, divided into four types, according difference surface bright characteristics. Through adopting low-temperature liquid nitrogen adsorption desorption, applying Kelvin equation, we obtain...
As a key mechanism of belt conveyor, the health status and working state its parts have profound impact on whether conveyor can run normally safely. In composition standard number rollers is numerous scattered. At same time, under complex environment work site, fault detection each roller particularly difficult. order to solve above problems, diagnosis method based thermal infrared image features proposed detect faults in conveyor. Firstly, position idler identified YOLOv4 identification...

Considering that liquid nitrogen (LN2) refracturing may become a potential coalbed methane extraction technology, this study systematically studied the changes in physical mechanics, permeability, and fracture behavior of coal treated with LN2 freeze–thaw using experimental methods such as uniaxial compression, acoustic emission monitoring, scanning electron microscope (SEM) permeability testing, three dimension (3D) cross-sectional scanning. The crack phase field model was used to reveal...
In the context of information age, smart buildings, as a product intersection architecture and technology, have become an important symbol global economic integration social informatization development. Nonetheless, despite increasing significance intelligent application philosophical theories in their conceptualization, implementation, operational maintenance stages remains insufficient. This insufficiency, to certain extent, constrains depth theoretical exploration breadth practical within...
Abstract Poly(butylene succinate)/bamboo fiber (BBF) biocomposites were prepared by melt blending method. Microencapsulated ammonium polyphosphate (MCAPP) was used as flame retardants to prepare retardant BBF biocomposites. The thermal degradation and properties of investigated. volatilized products the biocomposite are saturated hydrocarbons, unsaturated alkane, CO 2 , carboxylic acid, acid anhydride, aromatic compounds, NH 3 CH OH. peak heat release rate (pHRR) total (THR) BF decrease...
An algorithm based on the YOLOv5 model is proposed to address safety incidents such as tearing and blockage at transfer points belt conveyors in coal mines caused by foreign objects mixed with flow. Given tough underground conditions images acquired low quality, recursive filtering MSRCR image enhancement algorithms were utilized preprocess dynamic collected monitoring devices, substantially enhancing quality. The has been improved introducing a multi-scale attention module (MSAM) during...
In this paper, the fractal dimension of coal surfaces was calculated using theory, and influence different surfactants on surface studied. Six kinds sustainable traditional used in gas desorption processes were compared analyzed. We mineral fertilizer from Huainan Liuzhuang, China, as research object studied sodium dodecyl benzene sulfonate (SDBS), cohol diethanolamide (CDEA), nonylphenol polyoxyethylene ether (NP-10), tea saponin, sucrose ester rhamnolipid to modify coal. The methane...
Deep-hole presplitting blast technology is an effective method to intensively increase the permeability of coal seam and high-efficiency extract gas. Aimed at drivage shaft working place opening No. 13-1 Coal influenced by fault in Panyi Mine, this paper comprehensively took advantage deep-hole intensified increasing permeability, reinforcing body using metal skeleton, as well damming extracting gas outside diminished outburst risk only after 18 days, got purpose rapidly diminishing risk....
False information that appears similar to trustworthy media content, or what is commonly referred as ‘fake news’, pervasive in both traditional and digital strategic communication channels. This paper presents a comprehensive bibliographic analysis of published academic articles related news’ the concepts truthiness, post-factuality, deepfakes. Using Web Science database VOSViewer software, papers on these topics were extracted analysed identify visualise key trends, influential authors,...
Microwave and liquid nitrogen have shown great potential applications in the mining, geological, petroleum, particularly metal mining fields. In order to further promote their application rock tunneling engineering, this paper conducted a series of I-model fracture tests on hard (granite) explore impact nitrogen, microwave, microwave pretreatment characteristics rock. The results showed that compared with control group, all groups had varying degrees reduction wave speed toughness, especially group.
The degree of irregularity and complexity the pore structure are comprehensively reflected in fractal dimension. porosity coal was determined by its dimension, where a larger dimension indicates lower porosity. Fractal theory Frenkel–Halsey–Hill (FHH) model were applied to explore variation rules concentration on functional groups this study. Combined with infrared spectroscopy (FTIR) low-temperature nitrogen adsorption, starch-polymerized aluminum sulfate composite fracturing fluid...
Purpose – The purpose of this paper is to understand a flameproof distance necessary avoid the flame harms underground personnel which may have great significance safety and disaster relief gas explosions in coal mines. Design/methodology/approach Through roadway with length 100 m cross-section area 80 mm×80 mm, propagation premixed methane-air deflagrations were simulated by using AutoReaGas software for various fuel concentrations (7, 8, 9.5, 11, 14 percent), volumes (0.0128, 0.0384,...
Coal mining in sea areas has higher requirements for geological support systems, technical equipment levels, and safety production capacities because of the complex engineering conditions underwater coal mines. In this paper, deformation failure mechanism stability control a typical swelling soft rock roadway Beizao mine area are studied. A series mechanical experiments theoretical analyses were conducted to research properties reasons roadway. The type large-deformation was identified as...
Coal quality rating can help reduce greenhouse gas emissions, solving the global warming problem. It becomes more important as carbon neutrality by mid-21st century agreement is accepted 195 countries, including China. In this paper, an improved fuzzy comprehensive evaluation method introduced for coal rating. The data used in work are of Hostolgoi coalfield Xinjiang Province Six industrial analysis indicators determined factors taking samples different seam depths mining area....
