Tailings ponds can recycle water resources through the recirculation system by clarifying and purifying wastewater discharged from mining production process. Due to factors such as flooding heavy rainfall, once a tailings dams burst, spread of metals in causes underground surface pollution, endangering lives properties people downstream. To effectively assess potential impact bursting, many problems difficulty taking values predicting volume silt penetration empirical formulae, model...
The Da-Xiao Liangshan Mountains serve as a crucial ecological barrier in the upper reaches of Yangtze River China. This study uses high-precision land use and cover data from 1980 to 2020, applying kernel density analysis, topographic gradient classification, PLUS model, landscape pattern indices, standard deviational ellipse theory analyze spatio-temporal changes, differentiation, fragmentation, driving factors forest area. results reveal following: (1) From was one dominant types area,...
Tailings ponds are the indispensable facilities in mine production and operation. Once dam is destabilized damaged, it will pose a serious threat on life property of downstream population could also potentially cause an environmental disaster. With engineering background, this paper dynamically numerically simulates evolution process tailings flow from failure influence scope any resulting disaster context. The characteristics leaked analyzed at various riverbed slopes debris blocking...
This study adopted soil test and laboratory physical model experiments to simulate the tailings impoundment accumulation process according principle of similarity. Relying on practical engineering, it analyzed deposition characteristics dry beach surface during damming process, as well variation rules dam saturation line. Results suggested that, particles gradually became finer along inside impoundment. The particle size suddenly changed at junction between deposited water surface, which...
Abstract As one of the important influencing factors tailings dam stability, seepage field distribution within is often affected by mineral characteristics. While alkalinity or acidity reservoir water and long term immersion will partially change physical mechanical properties tailings. This study carried out permeability tests under action chemical solution. On this basis, a three dimensional (3D) model was constructed to analyze velocity effective saturation dam. Moreover, section along...
Different from conventional educational paradigms, online education lacks the direct interplay between instructors and learners, particularly in sphere of virtual physical education. Regrettably, extant research seldom directs its focus toward intricacies emotional arousal within teacher-student course dynamic. The formulation an emotion generation model exhibits constraints necessitating refinement tailored to distinct cohorts, disciplines, instructional contexts. This study proffers rooted...
Apparent particle size grading is the most important characteristic of super-high dumping site. On basis development HHC-CA model and on-site survey granular distribution, slope current situation, had considered features grading, was established according to a FLAC3D used analyze stability situation various piling up patterns based on model. The results indicated that upper displacement vector, whose direction maintained same site, performanced for subsidence. middle vector showed shear...
Based on self-designed tailings dam simulation experiment device of dam-break, experimental study failure was carried out under the condition rainfall.The change rule infiltration line, developing process, mechanism and displacement body after collapse were obtained recorded by rainfall devices, line measuring monitoring devices camera.The results are as follows: in early stage rainfall, changes front reservoir outside slope obviously lagging behind water level, but middle tail it not...
The scale effect is an unavoidable problem in the laboratory test of coarse‐grained materials. By combining self‐developed cellular automaton program with experiments, a method simulating triaxial materials was proposed this paper, and numerical specimen that can characterize discontinuous, nonuniform, heterogeneous characteristics bulk geotechnical established. parallel grading adopted to create six curves for simulation based on one situ curve. failure process strength deformation were...
The researchers cannot control the composition and structure of coarse grained soil in indoor experiment because granular particles different size have characteristics random distribution no sorting. Therefore, on basis laboratory tests with soil, HHC-Granular model, which could simulate sorting coarse-grained was developed by use cellular automata method. Meanwhile, triaxial numerical simulation experiments were finished variation shear strength discussed. results showed that internal...
