In response to the complex geological conditions of Yangquan Fifth Mine in Lu’an Chemical Group, which have resulted in the waste of a large amount of coal resources, the main reasons for the high loss rate of coal mines was analyzed. Targeted methods were proposed to improve coal mine resource recovery, including enhancing the foresight, accuracy, and effectiveness of geological prediction and forecasting, strictly formulating the management measures for top coal caving, reasonably adjusting the coal cutting and discharging processes, strengthening communication between functional departments and frontline production units, and enhancing supervision of coal transportation, washing and processing processes. By taking the above measures, the recovery of coal resources can improve greatly.

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.

High energy-consuming industries serve is a critical pillar of the national economy. Meanwhile, it is a primary source of energy consumption and environmental impact. Resource conservation and environmental protection have always been pivotal topics throughout China’s economic development process, playing a crucial role in advancing the sustainable development of Inner Mongolia’s energy bases. A theoretical framework for ecological efficiency within high energy-consuming industries in Inner Mongolia was constructed, and an ecological efficiency indicator system was established, in order to lay the groundwork for the transformation and development of Inner Mongolia’s high energy-consuming industries. The goal is to guide these industries toward more efficient resource utilization and environmentally friendly operations, thereby fostering a harmonious coexistence among the economy, society, and the environment in Inner Mongolia, and achieving sustainable development objectives.

The implementation of the new urbanisation strategy promotes the construction of resilient cities, which is an important force to promote the sustainable development of the region. Based on the five dimensions of population development, economic development, social development, ecological development, and the development of residents’ life, an evaluation index system for the level of new urbanisation was constructed, and the time and space of the development level of new urbanisation of the Pearl River Delta were analyzed as an example. The time and space evolution characteristics of its new urbanisation development level were analyzed. The results showed that the development level of new urbanisation in the Pearl River Delta shows an upward trend from 2013 to 2022, but the development is unbalanced among cities. In time, the comprehensive score of new urbanisation in the Pearl River Delta rose year by year from 2013 to 2022, with the average annual score increasing from 0.354 to 0.498, and the growth rate of the development level fluctuating greatly. Spatially, the spatial changes in the level of new urbanisation in the Pearl River Delta in 2013, 2018 and 2022 are small, with large regional differences, showing a spatial pattern of slowing down from the central to the eastern and western regions.

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.

Changzhou has a complete manufacturing industry system and over 60 000 industrial enterprises. Against the backdrop of increasingly complex and challenging domestic and international economic environments, small and medium-sized manufacturing enterprises in Changzhou are facing various difficulties and challenges in their production and operation. It is necessary to take technological innovation as the guide, actively implement the “Intelligent transformation digital transformation networked connectivity”, and plan ahead for digital infrastructure construction. Combining “external introduction” and “internal education” to build a service provider resource pool,and serve enterprises in cloud computing, data utilization, diagnosis, and intelligence. Create an industrial ecological service circle, combine “point line and surface”, demonstrate and lead, and take various measures to create a typical integration of data and reality. Cultivate new quality and productivity of Changzhou’s manufacturing industry, and build a modern industrial system with advanced intelligent manufacturing industry as the backbone, in order to further promote the high-quality development of Changzhou’s manufacturing industry.

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.

The Hebei provincial government actively supports the participation of social capital in the construction of public projects, but there are significant differences among prefecture-level cities, mainly due to the influence of business environment factors. By collecting the business environment data of 11 prefecture-level cities, fuzzy sets qualitative comparative analysis (fsQCA) method was used to integrate seven anthems from the three levels of government, market, legal and policy environment, and explore the influence of the combination of factors on social capital’s participation in public project construction. It is found that the combination of these factors significantly affects social capital participation. The research conclusion shows that it is recommended that local governments strengthen the financial support for social capital to participate in public projects, and ensure the operation of project funds by broadening the sources of funds, strengthening supervision, personalized policy support and cooperation with financial institutions. At the same time, it is also necessary to pay attention to the boundaries of government supervision, avoid excessive market decision-making, and give social capital a certain degree of discretion.

As one of the settlements of the elderly in China, the aging problem is prominent, and it is of great significance to carry out the transformation of the public space of urban villages for aging. Based on the field investigation questionnaire, taking Chen officer camp community and new beach community, as an example, theory of SEM(structural equation model) was used to build urban public space aging evaluation system from security, convenience, comfort and participation. Amos software was used to summarizes the problems of public space. In order to optimize the public space of the elderly in urban villages, transformation strategies are proposed from the entrance space, street space, square space and idle space, which will provide reference for the reconstruction of urban villages in Lanzhou.

With the continuous advancement of urbanization, urban industrial transformation and the implementation of urban renewal actions, the focus of urban development has further emphasized the improvement of quality and quantity. As one of the areas with the longest development in the entire city, the old industrial area has rich industrial heritage, resources and environment in the factory area, which is no longer suitable for large-scale transformation and reconstruction. How to build a reasonable renewal and transformation model for old industrial areas is one of the practical problems that need to be solved in the context of urban renewal in various cities. Taking Lanzhou General Machinery Factory as an example, based on the theory of urban acupuncture, the historical evolution was grasped, and the analysis of current problems was conducted. Four renewal steps are proposed, including breaking the meridians, replenishing qi and activating blood circulation, combing the meridians, and harmonizing the internal organs, providing new ideas and methods for the renewal of old industrial areas in cities.
