Particle size of nanomaterials has significant impact on their photocatalyst properties. In this paper, TiO2 nanoparticles with different crystalline sizes were prepared by adjusting the alkali-hydrothermal time (0-48 h). An annealing in N2 atmosphere after hydrothermal treatment caused reduction and created defects, resulting visible light photocatalytic activity. The evolution physicochemical properties along increase at a low alkali concentration been revealed. Compared other samples,...
Understanding the mechanism of progressive debonding bolts is great significance for underground safety. In this paper, both laboratory experiment and numerical simulation pull-out tests were performed. The experimental test specimens prepared using cement mortar material, a relationship between strength bolt uniaxial compressive (UCS) material specimen was established. locations crack developed in process identified acoustic emission (AE) technique. reproduced 2D Particle Flow Code (PFC2D)...
Premature failures of cable bolts caused by durability degradation in underground reinforcement systems have been more and often observed. To identify various factors affecting the corrosion process, processes were examined through laboratorial testing programs as well hydrogeochemical modelling. Experiments carried out simulated conditions "corrosion cells" containing stressed bolt specimens groundwater, clay, coal or a combination materials. Water chemistry pattern analysis different...
This study presents a novel analytical model to simulate the axial strain and stress distribution along full embedment length of grouted rock bolt under loading. The is derived based on force equilibrium equation at one infinitesimal section grout interface solved using second order partial differential method. Such advanced in way that all input parameters can be pre-determined by geometry information direct shear testing without need conduct any pull-out test. In addition, this first...
The composite strata structure is a common geological formation in western China. study of the failure characteristics great help to stability evaluation stope and prediction coal mine dynamic disasters. In order influence different hard rock coefficients on instability samples, triaxial tests with progressive varying confining pressure simulating field loading condition were conducted eight groups samples coefficients. bearing capacity was tested using RMT-150B compression equipment, while...
With continuous improvement of the synthetic aperture radar (SAR) resolution, 2-D defocus effect in SAR image resulting from uncompensated motion error has made autofocus become a new challenging problem. Conventional approaches assume that phase is absolutely unknown and estimate them directly. Due to high dimensionality parameters, these often suffer computational burden low accuracy. In this paper, we analyze range migration algorithm (RMA) processing on echo phase, reveal analytical...
In this study, based on compiled numerical-experimental datasets, important variables, including porosity, density, compressional and shear wave velocity, were utilised to develop a novel model for predicting coal permeability with high accuracy. Multiple linear regression, response surface methodology gene expression programming employed empirical models the foregoing variables. The performance of developed was evaluated using statistical indices. results showed that GEP-based has best...
This study explores the efficiency of using carbon dioxide (CO2) to extract shale gas, highlighting its potential enhance extraction while mitigating environmental CO2 pollution. Given intricate microstructure shale, injection inevitably induces deformation within reservoir's internal microstructure, thereby impacting gas displacement efficiency. The organic matter (kerogen) network and fracture in serving as primary spaces for adsorption migration, exhibit complex microstructural...
Abstract Many underground mining operations require the design of pillars that their long-term structural integrity under creep loading is essential for sustainable operation mines and safety personnel. Characterizing mechanical behavior rocks at different shapes over can assist in efficient pillars. Over past 4 decades, a large number studies have examined shape effect separately, while consideration these two together essential. Accordingly, comprehensive investigation needed to assess...
