Ground settlement prediction during mechanized tunneling is of paramount importance and remains a challenging research topic. Typically, two paradigms are existing: physics-driven approach utilizing numerical simulation models for prediction, data-driven employing machine learning techniques to learn mappings between influencing factors the settlement. To integrate advantages both approaches assimilate data from different sources, we propose multi-fidelity deep operator network (DeepONet)...
Mg-Li alloys are one of the lightest structural materials, but suffer from severe corrosion due to hyperactivity Mg and Li. In this work, an electrically conductive corrosion-resistant chemical conversion coating was fabricated on a duplex alloy LA103Z by two different routes: first route using conventional immersion treatment (Im-PCCs); second brushing (Br-PCCs). Results demonstrate that composition coatings remained, surface morphology altered. The Im-PCC depicts many lamellar CaHPO4 when...
The "three shells" cooperative support technology was proposed herein according to both the large deformation of rock surrounding large-section chambers in deep mines and precarious stability structures therein. development range plastic zone controlled by a stress shell reduce difficulty controlling rock. Additionally, residual strength mass self-bearing capacity were improved reinforced load-bearing shell. Furthermore, passive could restore triaxial state on free surface, influence...
Abstract Polyanionic material, specifically the NASICON‐type is considered a promising cathode material for Na‐ion batteries (SIBs) because of its stable structure and high operating voltage. Further, it improves energy density correlated with well utilization all Na in compound. For 3 V 2 (PO 4 ) F (NVPF), extraction third Na, reported as electrochemical inactivated, can be realized at voltage region while forming an irreversible tetragonal phase. In this study, we introduce Ti doping to...
To address the challenges of low accuracy in coal gangue image recognition and poor segmentation performance under influence dust underground mines, a scaled simulation platform was constructed to replicate longwall top caving face. This utilized real particles as raw material employed mimic conditions typically found mines. Images without varying concentrations were then collected for analysis. In parallel, an improved DeeplabV3+ model is proposed, where ResNeSt backbone network DeeplabV3+,...
Coal production in China accounts for 1/3 of total output the world, and nearly half China's is extracted thick coal seams. Therefore, it significant to study fully mechanized mining technology The development, current situation, issue slicing mining, top-coal caving, seams cutting sufficient height with are systematically analyzed this paper. According result analysis, prospect development discussed. Especially, authors have represented key problems which block
This paper puts forward the concept of key strata in immediate roof (KSIF) and studied dynamic effect control mechanism KSIF. The results show that KSIR controls caving its upper strata; break has direct impact on lower this increases along with increase thickness hardness decrease distance to working seam. main can easily form bilayer structure “Cantilever-Masonry beam.” Support work load is affected by position, thickness, KSIR. support increased condition face.
As a non-explosive low-disturbance rock breaking technology, carbon dioxide phase transition blasting (CDPTB) is widely used in projects such as pressure relief and permeability enhancement coal mines, open-pit mining, road subgrade excavation, foundation pit etc. In this paper, the principle equipment of CDPTB are systematically analyzed, characteristics reusable fracturing tube disposable determined. Different energy calculation methods analyzed to determine magnitude or equivalent...
