To address the issues of multi-source coupling, noise interference and insufficient frequency-domain characteristics in process data, this paper proposes a multi-channel fusion prediction model based on time series correlation and frequency-domain enhancement, termed MTS-MCF. The Pearson correlation coefficient method was used to screen input variables, and a time series correlation network (CorNet) was constructed to achieve dynamic label propagation. The coupling weights of parameters were quantified using a frequency-domain enhanced channel attention mechanism (FECAM), and the network response was optimized with the ELU activation function. Experimental results show that compared with the benchmark models, the proposed model reduces MAE for gold and silver by more than 5.7%, reduces MSE by more than 6.3%, and increases   by more than 6.3%, outperforming mainstream models such as MTS-mixers and providing effective technical support for production control.

Although bilateral trade in goods between China and In-dia has been growing rapidly, the trade status is unequal, and there is a structural convergence of exportproducts. Based on the data from 2000 to 2023, India's trade remedy measures against China show alarge total volume, various types, and a relatively concentrated scope. The core reasons lie in the lack ofmutual trust in development between the two countries , India's huge trade deficit, its competitive disad.vantage in goods trade , and the fact that resource-intensive products are more competitive than complementary. Therefore , this paper proposes strategies to optimize China-ndian trade in goods, including en.hancing inter-governmental coordination on trade, improving the response measures of govermments andenterprises to India's trade remedy actions, and shifting towards the export of capital-intensive products.

The key stratum theory is applied to determine the fracture spacing of overlying strata and theheights of the three zonesin upward mining. FLAC3D numerical simulation software is used to analyze themovement law of overlying strata at different mining heights. Orthogonal experiments are conducted to op-limize roadway location selection. The following conclusions are drawn: 1) Due to the influence of keylayers, the height of the fracture zone increases abruptly with the increase of mining height. Each abruptinerease indicates that a key stratum has fractured and formed a voussoir beam structure. 2) The plasticzone of the working face exhibits a saddle-shape distribution (high at both ends and low in the middle).As mining height increases, the difference between the plastic zone above the mining boundary and thatin the middle decreases. The advance stress concentration coefficient and lateral stress concentration coef-ficient increase linearly with mining height, and their peak positions move farther away. 3) The influencing factors, in descending order of weight, are normal distance, horizontal distance, and mining height.The optimal roadway location is at a mining height of 2 meters, with a normal distance of 140 meters fromthe mining face and a horizontal distance exceeding 20 meters from the mining site boundary. Anormaldistance of 60 meters and a horizontal distance of 20 ~ 40 meters define a stress concentration zone,which is unsuitable for roadway placement. Related Articles | Metrics | Comments（0）

This study systematically analyzes the current status and evolutionary context of green mine construction in China, exploring pathways for deep decarbonization of the mining industry. Through policy text analysis and typical case studies, it reviews the development of the green mine standard system and constructs a full-chain carbon footprint accounting model covering the "exploration-mining-processing-restoration" lifecycle using the Life Cycle Assessment (LCA) method. The research innovatively proposes a three-dimensional collaborative technical framework of "resources-energy-carbon sink", integrates new quality productivity elements such as intelligent sorting and digital twins, and designs an integrated transformation model comprising "green mining+clean energy substitution+carbon capture, utilization, and storage". TheResults show that: 1) China has initially established a multi-level green mine policy system, but regional economic development imbalances lead to significant differences in implementation outcomes, restricting the carbon peak process; 2) clean energy substitution (e.g., photovoltaic, green hydrogen) and solid waste recycling can reduce the mine carbon emission intensity by more than 30%, serving as core decarbonization pathways before carbon neutrality; 3) as a key support for deep decarbonization, CCUS technology currently faces bottlenecks of high costs and insufficient large-scale deployment, which need to be overcome through green hydrogen coupling and carbon market linkage mechanisms. Based on these findings, the study suggests improving national standards for carbon footprint accounting, establishing a fiscal-carbon market linkage mechanism for CCUS, and accelerating the deep integration of intelligent technologies with mining scenarios, thereby building a new green mine development paradigm driven by "policy guidance, technology impetus, and market regulation". The research results not only provide technical support and institutional guarantees for China's mining industry to achieve carbon peak and carbon neutrality, but also offer a Chinese solution for the global low-carbon transformation of the mining industry.

How to quickly acquire high-precision normal height has be-come one of the recent research topics in the field of surveying and mapping. This article proposes aGNSS elevation filtting method that considers two global gravity field models, namely EGM2008 and SGG-UGM-2. First, the gravity field model is used to generate gravity quasi-geoid; then a difference surface isgenerated based on the measured data and the gravity field model. Finally, the difference surface is fusedwith the gravity quasi-geoid to fit the gravity quasi-geoid to the actual quasi-geoid, thereby achieving thepurpose of correcting the gravity field models using the elevation anomaly points. In this paper, theEGM2008 and SGG-UGM-2 gravity field models are used, and the refined quasi-geoid model of YunnanProvince is adopted for accuracy verification. The test results, show that this method is stable and relia-ble, and can meet the requirements of common applications such as large-scale topographic mapping.

This paper deeply analyzes the development process and current status of intelligent video sur-veillance technology, and innovatively proposes the IAPVS (Intelligent Analysis Platform for Video Sur-veillance) design mode based on distributed edge computing. This mode consists of two core components:video edge computing nodes and a data center. Edge nodes are deployed on-site or in near-field environ-ment and the YOLO algorithm is used for video data preprocessing-accurately identify targets, filtering da-ta, and then uploading the processed data. The data center integrates muliple platforms and a model re-pository, enabling operations such as model training, correction and reuse. The logic design and workflowof IAPVS Platform are also elaborated in detail. This design breaks through the limitations of traditionalarchitectures, realizes end-edge-network-cloud collaboration, establishes an efficient intelligent supplysystem, and improves data processing and resource utilization. It provides a new overall solution for thedevelopment of video intelligent analysis platforms in diverse scenarios, facilitating the development of in-telligent video surveillance technology in China.

However, because of their affinities for iron and sulfur, Ga, Ge, and In are commonly associated with sphalerite and other sulfide minerals. During pyrometallurgical or hydrometallurgical zinc processing, trace amounts of these elements become enriched and remain in the slag. In this study, zinc electric furnace slag with relatively high contents of Ga, Ge, and In was used as the raw material. The leaching behavior of Ga, Ge, and In was investigated under various leaching systems (sulfuric acid and hydrochloric acid systems) by examining the effects of temperature, acid concentration, oxidant type, and oxidant dosage. The results showed that Ga, Ge, and In achieved leaching rates of 97.51%, 94.58%, and 98.73%, respectively, in the optimized two-stage hydrochloric acid oxidation leaching process. Furthermore, XRD and SEM analyses revealed that the high lead content in the raw material led to the formation of insoluble lead sulfate in the sulfuric acid system, which encapsulated the particles and inhibited the leaching of Ga, Ge, and In. In contrast, in the hydrochloric acid system, lead chloride forms coordination complex reactions, which redissolve the precipitated lead chloride. This effect effectively eliminates the particle encapsulation barrier and realizes the efficient and synchronous leaching of Ga, Ge, and In, providing a feasible technical route for the extraction and utilization of scattered metals.der complexation, leading to the dissolution of lead species and effectively preventing encapsulation. As a result, efficient and simultaneous leaching of Ga, Ge, and In was achieved, providing a promising approach for the extraction of these strategic metals from zinc smelting residue Related Articles | Metrics | Comments（0）

Linear programming is a more traditional approach characterized by simple program structure and a strong focus on procedural flow. However, it often results in a bloated main program, disorganized functional logic, and poor readability and maintainability of the code. Modular programming emphasizes functional independence and modular invocation, featuring clear program structure as well as improved code maintainability and reusability. In multi-channel temperature control system based on MCU, modular programming can be applied to functional modules such as temperature detection, temperature display, and time-delay operations. This approach ensures that each functional module maintains its operational independence while retaining connectivity with other functions, thereby resulting in a more systematic and rational program design.

The feasibility of manganese tailings concrete (MC concrete) was investigated through mix design, performance testing, and heavy metal leaching toxicity analysis. The experimental results show that: 1) The manganese tailings slag aggregate complies with the Class III requirements of GB/T14684—2022 and GB/T14685—2022. 2) Under full aggregate replacement, the workability of MC is comparable to that of natural aggregate concrete, and its 28-day compressive strength reaches 43.62 MPa. Moreover, it effectively immobilizes heavy metals, resulting in low leaching and minimal environmental impact. 3) Through this approach, critical issues associated with industrial waste disposal and natural resource exploitation can be addressed. The overall cost is reduced by 40%～50%, and the exploitation of natural resources is correspondingly reduced, contributing to the green, environmentally friendly, and economically sustainable development strategy of "carbon peak and carbon neutrality".

Fault Feature Extraction of Planetary Gearbox Based on Fusion of VMD and Improved M-SVD ＨＡＯＺｈｏｎｇｂｏ１, ＹＥＮｉｎｇ２, ＨＡＯＸｉｎｙｕ HPMug2oMmNrOfxWQHLiEksa6s0hFu9Ox348d7QefarYlaFR5ArkhOwm3Da1pmxmxCtenj1+6luWD#r#n+EPn9L6Ce+9onqnMlT+i    2026, 42 (1): 43-.   DOI: 10.3969/j.issn.1009-0479.2026.01.006 Abstract （67）      PDF（pc） （2563KB）（14）       Knowledge map    Save To address the difficulty in effectively separating fault components from noise components during the extraction of weak pitting fault features of planetary gearboxes, which leads to insufficient suppression of noise burrs and incomplete preservation of fault feature information, a feature extraction method combining Variational Mode Decomposition (VMD) and improved Multiscale Singular Value Decomposition (M-SVD) is proposed. Firstly, an objective function based on minimum envelope entropy is constructed, and a VMD signal decomposition method incorporating Sparrow Search Algorithm (SSA) is proposed to achieve adaptive decomposition of the original signal. Secondly, the square envelope spectrum kurtosis is selected as an indicator to screen and reconstruct the VMD decomposition components, thereby removing most of the noise burrs from the original signal. Then, considering the sensitivity of the mean to the overall trend variation of vibration signals, a signal processing method based on improved M-SVD isdesigned by combining the mean singular value with sample entropy. Finally, envelope demodulation is performed on the signal processed by improved M-SVD to extract the weak fault features of the planetary gearbox. Using SNR and RMSE as quantitative metrics, the proposed method is compared with the standalone SSA-VMD, the improved M-SVD, and the original M-SVD methods in pitting fault feature extraction experiments. The proposed method effectively suppresses noise components while maximizing the retention of fault feature information. Related Articles | Metrics | Comments（0）
