In the construction project, rock mass is often destroyed from joint plane, and jointed easy to be eroded by freeze-thaw environment. Therefore, damage mechanical properties of filled under action are very important for disaster prevention, engineering safety evaluation reinforcement. order research effect cycle on deterioration characteristics rocks, prefabricated samples tested with different numbers cycles temperature range -20°C~20°C. Then wave velocity test, static compression test SHPB...
Heterojunction structures significantly influence the performance and function of β‐Ga 2 O 3 ‐based photodetectors through their unique material combination interface control. The electronic structure, photoelectric properties, mechanism g‐ZnO/β‐Ga heterojunction are analyzed using first‐principles calculations. results show that is a direct bandgap semiconductor, featuring an internal electric field directed from g‐ZnO layer to layer. It demonstrates strong light absorption response in UV...
In this paper, stope structure optimization during sublevel caving mining is considered under the condition that isolated draw zones (IDZs) are nonstandard ellipsoid, which realized by dynamically adjusting arrangement of IDZs and quantifying degree intersection according to an ore profit loss calculation model. A dynamic intersecting model based on was proposed, can adjust height drift spacing ore-rock bulk flow parameters, economic indicators, occurrence body, drilling machine, so forth....
In underground metal mines, goaf brings huge safety risks. It is an important part of mine to evaluate stability and determine the best handling measures. However, evaluation decision are often separated; they need be unified. Meanwhile, for a complex system engineering rock masses in mining, subjectivity exists process. Under these conditions, it necessary minimize subjectivity, results also considered comprehensively determining this paper, fuzzy theory was adopted based on fact that...
Abstract Theory assumes that the friction along discontinuous interface is uniform, and selection of uniform distribution resistance a simplification actual physical process. This assumption leads to unsafe design. Therefore, numerical simulation experimental methods are used study slip with non-uniform friction. model comprised two blocks completely matching contact interfaces. The coefficient one part surface differed from other, resulting in interface. was simulated under biaxial...
A positioning grid is a key clamping structure for fixing the transverse and axial positions of fuel assemblies in nuclear reactors, it generally prepared by stamping Zr-4 sheet. However, texture formed processing process sheets can affect formability, resulting cracking process. Therefore, relationship between formability normal Kearns factor (Fn) basal was studied this paper. The results showed that sheet with an Fn equaling 0.720, isobaric reduction rolling process, would crack To avoid...
The point load test (PLT) is intended as an index for rock strength classification or estimations of other parameters because it economical and simple to conduct in the laboratory field tests. In literature, calculation procedures cylinder cores, blocks, irregular lumps can be found, but no study has researched such half‐cylinder cores. This paper presents numerical model tests specimens. results specimens are then presented, analysed, discussed. A correlation failure between established...
Coal gangue is a solid waste discharged during the coal production process, consisting of rocks and minerals, nonmetal mineral resource with attributes suitable for comprehensive utilization. This study explores pre-classification issue utilization through image recognition methods. Initially, was categorized into four types – Residual coal, Gray gangue, Red White gangue-based on its appearance, chemical composition, phase usage characteristics. Subsequently, color features, texture shape...
Cavability assessment is an important subject during the feasibility stages before determining whether to use block caving mining. This paper provides a fuzzy comprehensive ( FCA ) approach based on cavability approaches and its influencing factors, which are all fuzzy. combines factors with engineering empirical by mathematics, improves applicability of results. applied assess via cores in Luoboling copper molybdenum mine. The spatial distribution rock mass at different depths borehole...
Abstract Sericite schist is an extremely soft rock, which characterized by obvious rheological properties and large creep deformation. The residual soil of in unsaturated state for most the time. When encountering water, it interacts with has a great influence on its strength. In this paper, one dimension three axis tests are carried out using quadruple consolidation apparatus triaxial apparatus. results show that process can be divided into stages: rapid growth stage, slow stage stable...
It is of great significance to study the mechanical properties rock fracture for stability engineering projects. The properties, including normal compression and shear fracture, are studied by a series tests considering effect lateral stress using self-developed true triaxial test apparatus. results show that initial stiffness maximum closure value increase with stress, peak strength dilatancy angle whereas displacement decreases stress. Considering improved loading model, model established....
In caving mining, the successful initiation and propagation of require one low‐dip joint set. However, not every mine has a The Hemushan Iron Mine in China was taken as engineering background, characteristics rock mass with inclined joints were analyzed based on synthetic (SRM) model. First, investigated Mine. Second, model parameters determined geological conditions mine, seven models established. Third, process simulated, monitored. For after undercutting, research showed that crack zone...
