This paper presents the zonal geochemistry and elasticity characteristics of gallium- lithium-rich No. 6 coalbed in Haerwusu mine discusses interpretation methodologies coal-hosted gallium lithium resources using lab-measured samples field-measured wireline logs. The results demonstrate that both coal-composition-based elastic-parameter-based classifications yield similar results, categorizing into subzones related to coal quality. Material compositions, elastic properties, critical metals,...
Accurately predicting geological structures (GS) ahead of tunnel excavation is paramount importance for ensuring safety in coal mines. Standard time or frequency analysis methods face significant challenges due to limitations downhole environments and ground penetrating radar (GPR) instrument performance, hindering the acquisition precise information. Time-frequency (TF) analysis, capable simultaneously examining non-stationary signals both domains, has become an important tool interpreting...
Background Disseminated superficial actinic porokeratosis (DSAP) is an uncommon autosomal dominant chronic disorder of keratinization, characterized by multiple keratotic lesions surrounded a slightly raised border. Thus far, although two loci for DSAP have been identified, and the genetic basis pathogenesis this not elucidated. Objectives To determine locus identify candidate gene(s) disease. Methods Genome-wide scan linkage analysis were performed in six-generation Chinese family with...
Abstract Ecosystem issues have been severely concerned and studied when the coal resource is one of major energy generators, green mining innovation techniques involving artificial-restorations addressed significantly lessened negative impacts on ecological environment. The ecosystem a coal-mined area, however, able to naturally restore with processes natural succession, similar human body system that has immune ability self-heal wound over time if does not deeply hurt health. Here we...
Disseminated superficial actinic porokeratosis (DSAP) is an uncommon autosomal dominant chronic keratinization disorder, characterized by multiple keratotic lesions surrounded a slightly raised border. Thus far, although two loci for DSAP have been identified, the genetic basis and pathogenesis of this disorder not elucidated yet. In study, we performed genome-wide linkage analysis in three Chinese affected families localized gene 8.0 cM interval defined D12S330 D12S354 on chromosome 12....
The determination of quantitative relationship between soil dielectric constant and water content is an important basis for measuring based on ground penetrating radar (GPR) technology. calculation volumetric using GPR technology usually the classic Topp formula. However, there are large errors measured values calculated when formula, it cannot be flexibly applied to different media. To solve these problems, first, a combination shallow drilling used calibrate wave velocity obtain accurate...
The attenuation characteristics of a medium involve the absorption electromagnetic wave energy during its propagation and represent crucial parameter for describing properties subsurface media. Due to complex nature signal attenuation, demanding consideration numerous parameters, quantitative analysis is challenging. Time-frequency (TF) promising technique that simultaneously analyzes nonstationary signals in time frequency domains. Although characterization factors using TF tools can be...
Shallow-buried high-intensity mining (SHM) activities commonly in China’s western area will lead to the decrease of groundwater level and soil water content (SWC), which aggravate further deterioration local fragile ecological environment. In this study, applicability limitations six typical dielectric models were comprehensively evaluated based on ground penetrating radar (GPR) technology shallow drilling methods. Moreover, experiments performed test variation SWC Ningtiaota minefield...
To study the influence of coal mining on porosity shallow sandy loam under conditions seam in thick, loose layers north-west China, a typical surface stratum Shaanxi Province was taken as area, and experiments were performed to test variation soil at different depths 0–10 m strata before, during after therein. The experimental results demonstrate that overall average porosities disc-shaped edge area basin bottom subsidence centre increased by (23.51, 18.07 22.61%) respectively compared with...
To investigate the radioactivity levels of seawater, sediments, and biota in Daya Bay sea area, China, order to establish baseline values, provide basic data for assessment potential radiological risks that might result from application nuclear technology or human activities. Samples were collected area analyzed. Their then compared with information other regions China around world reported related literature. For seawater samples, activity concentrations natural radionuclide 40K 9.9–10.4...
As a new type of progressive energy release propellant, nitro gradiently distributed propellant (NGDP) was prepared by denitration reaction between reagent and the to remove energy-containing functional group (-O-NO2) from surface propellant. The kinetics determines distribution nitrate in layer NGDP, which further affects combustion progressivity. In this paper, kinetic model for process cylindrical single-base gun studied shrinking unreacted core (SUC model). change particles before after...
Abstract Accurate prediction of the spatial location underground pipelines is crucial to ensure safe operation pipelines. However, traditional ground penetrating radar (GPR) relies too much on image data quality and detection personnel's experience. It can only estimate approximate pipeline. The acquisition electromagnetic wave velocity an essential part accurately interpreting Therefore, this paper's research proposes a processing flow that be applied multi-offset GPR, including multiple...
