The Huanglan coal mining area is the most threatened mining area in Hunan Province by water hazards, which seriously affects the sustainable development of the local coal industry. Accurate detection of hidden water hazards can effectively reduce the probability of hidden dangers, and exploring more efficient technical methods and using high-precision detection instruments are effective ways to solve this problem. Multi-polarized magnetotelluric technology (MPMT) measures electric field polarization at different polar distances at a common center point to obtain Kania resistivity at different polar distances, thereby obtaining more dimensional electric field data, local anomalies, and background data, which can more efficiently meet the needs of geological body detection in complex geological environments. According to the hydrogeological conditions of the Huanglan mining area, the multi-polarized magnetotelluric method was used to carry out work, analyze its application effect and electrical properties of the mining area, and prove the effectiveness of the method through known water body experiments and apply it to the whole area of water hazard exploration. The comparison between the interpretation results and the actual excavation conditions of later tunnels proves the accuracy of the method, providing a scientific basis for the design of drainage tunnels, drainage measures, and safety prevention of groundwater in the Huanglan mining area.

In previous studies, incomplete extraction of logging curve features and simpler model construction resulted in limited porosity prediction accuracy. In order to improve the prediction accuracy,the self-encoder, long and short-term memory network and the Attention mechanism were combined to construct the AE-LSTM-AT (auto-encoder-long short-term memory network-attention mechanism)model. the AE (self-encoder) unifies the feature distributions of the source domain data and the target domain data into the same space, in order to reduce the interference of the magnitude changes on the model due to the differences in data distribution, the modified LSTM(long short-term memory network) reduces the number of parameters while enhances the feature impact of distant time steps and reduces information pollution, and the introduction of the Attention mechanism dynamically calculates the attention weight of each time step, thus focusing on the key features more accurately and improving the performance and performance of the model in processing sequence data. a control group including MLP(multilayer perceptron machine) and LSTM was set up, and four sets of comparison experiments were conducted. It is proved that the model structure of has superior results in the problems of long-term prediction and cross-domain prediction.

On June 10, 2022, a 6.0-magnitude earthquake occurred in Caodeng Township, Marcang City, Aba Prefecture, Sichuan Province. The earthquake not only caused a large number of landslides and landslides, but also caused seismic cracking and deformation of the slope rock and soil mass. Taking the K39+280~K39+390 section of the newly built provincial road S220 from Ribu to Muerzha Bridge in the earthquake stricken area as an example, the rainfall disaster mechanism and prevention technology after slope seismic cracking and damage was studied. It is found that during seismic activity, the seismic Bora shear effect promotes the expansion of rock joints and fissures, leading to the relaxation of soil structures. As a result, seismic cracking damage is widespread and has a significant impact on slope stability. The pores, joints, and fissures in the rock and soil structure of earthquake damaged slopes have good permeability, which is conducive to rainfall infiltration, resulting in a rapid increase in soil moisture content during the rainfall process. Joint fissures continuously accumulate water, and the entire earthquake damaged deformation body gradually reaches saturation during the rainfall process, forming high-value water pressure near the potential failure surface. In addition, the lubrication and softening effects of pore water and joint fissure water reduce the frictional resistance between soil particles and rock structural surfaces, leading to a decrease in shear strength and promoting the stability of the deformation body to continuously decline until instability. Earthquake damaged slopes can be prevented and controlled by point surface combination. In areas with severe earthquake damage and deformation, frame anchor rods can be used for overall slope protection, while dangerous rock falling blocks are generally developed but relatively weak. The slope surface adopts the method of retaining at the foot of the slope (concrete retaining wall+steel grating) take protective measures.

In order to explore the disturbance mechanism of shield construction on composite strata,taking the coastal composite strata as an example, and relying on the Fuzhou Coastal Line, the disturbance mechanism of shield tunneling in composite strata was investigated.A refined numerical model of shield tunneling was established based on the finite element analysis software ABAQUS, and four parameters were considered, including face support pressure, grouting pressure, jack thrust, and cutterhead torque. After validating the model with on-site monitoring data, the settlement patterns of five composite strata traversed by the shield tunneling in the actual project were examined. The results show that the closer to the excavation area of the shield machine, the greater the disturbance; when the tunnel passes through composite strata, it causes more significant cutting in the softer layer, increasing soil disturbance.

An evaluation index system for agricultural science and technology (S&T) innovation capacity and agricultural high-quality development was constructed using the entropy method. By integrating these indices with a binary system coupling coordination degree model, the coupling degree and coupling coordination degree for provincial-level administrative regions from 2010 to 2020 were calculated. It is found that the agricultural S&T innovation capacity and the comprehensive index of agricultural high-quality development have shown a significant upward trend since 2010, reflecting the thorough implementation of the innovation-driven development strategy in the agricultural sector. The comprehensive index of agricultural high-quality development displays a distinct regional hierarchy: east > central > west > northeast. The eastern region leads in agricultural S&T innovation capacity, followed by the central and northeastern regions, with the western region showing relatively weaker innovation capacity. While the interaction between agricultural S&T innovation capacity and agricultural high-quality development is strong, the depth of this positive interaction remains limited. The system coupling degree has gradually increased and is nearing 1, indicating more frequent interactions between the two systems. However, the coupling coordination degree is significantly lower than the coupling degree, suggesting that the positive interactions between the systems are insufficient, and the potential synergies between them have not been fully realized. In response, several policy recommendations are proposed, including accelerating new quality agricultural productivity, improving the institutional mechanisms for agricultural S&T innovation, capitalizing on the advantages of the burgeoning digital technology sector, and advancing the development of smart agriculture.

Then, the Moran index was used to test spatial correlation. Finally, a spatial econometric model was used to explore the relevant factors in depth. It is found that the overall high-quality development level of strategic emerging industries in China shows a steady upward trend, but there is a clear regional imbalance, roughly showing a high in the east and low in the west. There is a positive spatial correlation of the industries in China, and the overall spatial distribution shows a clustering trend of “high-high” and “low-low”. The explanatory variables of technological innovation, economic development level, investment and construction, human capital, and openness have a significant positive effect on the improvement of the high-quality development level of the industries. Based on research findings, rational suggestions are proposed to enhance the competitiveness of strategic emerging industries and provide strong industrial support for the development of new quality productivity.

Returning home for entrepreneurship is one of the important measures to promote common prosperity. The rise of rural digital trade has accumulated rich previous experience, economic resources, and entrepreneurial opportunities for returning home for entrepreneurship activities, which can effectively drive the successful development of returning home for entrepreneurship, promote the spontaneous growth of rural economy, and inject more innovative vitality into rural economy. Digital trade can achieve common prosperity between urban and rural areas in terms of channels, resources, and markets by connecting urban and rural entrepreneurship channels, integrating urban and rural entrepreneurship resources, and opening up urban and rural entrepreneurship markets. Thereby, narrowing the wealth gap between small towns and rural areas. It is suggested to strengthen the role of digital trade in promoting entrepreneurship activities in rural areas by improving relevant legal regulations, promoting vocational training for rural returnees, and encouraging cross departmental cooperation among returnees, in order to better achieve common prosperity.

A favorable business environment can effectively improve the level of digital economic development in provinces. It is of great research significance to optimize the business environment in order to promote the digital economy. Using the research method of fsQCA(fuzzy-set qualitative comparative analysis), the path of as sit in the development of digital economy in the business environment was analyzed from the perspective of configuration. It is found that a single business environment element does not constitute a necessary condition for promoting the development of the digital economy. The market environment, government environment, and the legal and policy environment plays a pivotal and essential role in fostering the advancement and growth of the digital economy. The construction of the market environment is significantly lagging behind due to its regional characteristics. In order to create a healthy market environment, it is necessary to create a relaxed market atmosphere.

Based on the Chinese General Social Survey (CGSS) large-sample survey data, the impact of the public’s satisfaction of government environmental governance and the public participation effectiveness on government trust were empirically analyzed. It is found that the public’s satisfaction with the environmental governance of the central government (local government) has a significant positive impact on the trust of the central government (local government). However, the public’s satisfaction of the central government’s environmental governance has a significant negative impact on the trust of the local government. The study also shows that the process effectiveness and the result effectiveness of public participation have a significant positive impact on the trust of the central government and the trust of the local government respectively. Therefore, generally speaking, the improvement of the public’s satisfaction with the government’s environmental governance can enhance the government trust, but the relationship between the two is complex to some extent. Protecting the right of the public to participate effectively can enhance the trust of the governments, and “procedural justice” and “result justice” are both indispensable.

Credit risk, due to its high frequency and significant impact, is regarded as an intolerable risk and a critical factor influencing public-private partnership projects. The emergence of various credit risk issues can severely harm both private and public interests. Existing research and conducting an in-depth study of relevant core literature from the Web of Science and CNKI databases between 2010 and 2024 was reviewed by using VOSviewer and CiteSpace software. It is revealed that infrastructure projects, risk assessment, project bonds, and the selection of private sector partners are pivotal research themes in this field. Moreover, emerging collaboration models, ESG (environmental, social, and governance) factors, the application of new technologies, and cross-border cooperation are identified as promising directions for future exploration.

Based on CiteSpace software, 765 core literatures on the topic of resource-based city transformation were visually analyzed. The results show that the transformation research of domestic resource-based cities has experienced three stages: less attention, rapid development and stable development, and more attention has been paid to the study of countermeasures and effect evaluation of resource-based cities. The scientific research cooperation in this field is weak, and the core authors and core institutions have not been formed. The research mainly focuses on three aspects: economic transformation and industrial structure, sustainable development and environmental protection, technological innovation and cultural industry. In the future, it is suggested to deepen the exploration of transformation paths, strengthen interdisciplinary research, and empower the transformation of resource-based cities with innovation.

The future learning center is a new paradigm for the next generation of learning. Against the backdrop of rapid technological development and educational reform, university libraries are transforming towards the future learning center model to better adapt to the changing times. An in-depth analysis of 160 literature on the research of future learning centers in university libraries in the CNKI database was conducted based on CiteSpace and LDA(latent Dirichlet allocation)topic models. It reveals the current situation, hot issues, and development trends of research on future learning centers in Chinese university libraries, and reference suggestions for the construction of future learning centers in university libraries are proposed, such as unified standards, strengthening publicity, highlighting characteristics, personnel training, and co construction and sharing.

User behavior data is an important basis for decision-making in e-commerce enterprises. The AARRR(acquisition,activation,retention,revenue,referral) model, funnel analysis model, and user behavior analysis methods in the field of data analysis were explained. Based on the basic indicators and preferences of user behavior, a comprehensive analysis was conducted through multiple dimensions, and the conclusions drawn were presented in a graphical manner. Finally, the conversion rate in the user shopping process was presented in the form of a funnel chart. E-commerce enterprises can utilize user behavior research to provide customized services for individuals, thereby achieving refined market decision-making.

Innovation and entrepreneurship education encourages college students to actively participate in innovation and entrepreneurship activities, stimulate the innovation vitality and creative potential of the whole society, and promote the economic transformation and upgrading. Taking 6 780 valid questionnaires from comprehensive colleges and universities in Shandong Province as research samples, an evaluation scale of college students’ innovation and entrepreneurship behavior were constructed to identify the influence mechanism of “dual-creation” education on “dual-creation” behavior, and provide empirical evidence for colleges and universities to deepen the reform of innovation and entrepreneurship education and to explore the potentials of innovation and entrepreneurship among students, which provides empirical evidence for universities to deepen the reform of innovation and entrepreneurship education and explore students’ innovation and entrepreneurship potential. In the future, the government and universities should continue to broaden the channels of innovation and entrepreneurship practice by system construction, realize “theory+practice” teaching by curriculum integration, and create a good atmosphere of innovation and entrepreneurship by resource support, so as to contribute to the transformation and upgrading of the economy and the innovative development of the society.
