In this paper, the FLAC 3D simulation method is used to systematically study the water outburst problem of fluid coupling with coal mine floor. The results show that the vertical stress of the floor in the goaf has an obvious downward trend after coal seam excavation. Under the joint influence of mine pressure and bearing water pressure, the working face before the old roof pressure can be affected by two stages: the first stage is the advance pressure compression section on both sides of the working face, and the other stage is the pressure relief expansion section under the goaf. Before the old roof is pressed, the shear stress near the roof and floor is also affected to some extent. The front and rear displacement value of the goaf is negative, which is the result of the advance supporting pressure. The effective thickness of the floor waterproof layer decreases gradually with the advance of the working face. When the working face continues to advance, there will be a risk of water outburst. With the increasing width of the working face, the height of the guide belt increases. Therefore, in the process of mining activities, a variety of factors should be considered comprehensively, and a reasonable width of the working face should be selected to ensure the safety of mining.</p>","PeriodicalId":9908,"journal":{"name":"Chemistry and Technology of Fuels and Oils","volume":"16 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2024-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139770318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, the characteristics, genesis and main controlling factors of the Zhangxia Formation and the Sanshanzi Formation reservoir are studied through field section observation, thin section observation, drilling and geophysical logging data combined with experimental analysis data. The reservoir space types of the Cambrian carbonate rocks in the Ordos Basin mainly include intercrystalline pores, intercrystalline dissolution pores, dissolution pores, dissolution sutures and dissolution fractures, among which intercrystalline dissolution pores, dissolution pores and dissolution fractures constitute the most important reservoir space type. There are three reservoir types: pore type, fracture - dissolution cavity type and fracture type. The development of Cambrian strata in Ordos Basin is mainly controlled by three factors: high-energy sedimentary facies zone, epigenetic diagenesis and tectonic movement. Granular beach facies and dolomite tidal flat facies are favorable zones for reservoir development in Zhangxia Formation and Sanshanzi Formation. The fault zone in the basin provides a migration channel for late hydrothermal fluid, which can significantly improve reservoir performance. Tectonic fracture itself is an effective pore system, which becomes the migration channel of geological fluid, and also plays a role in communicating pores, which plays a positive role in reservoir.</p>","PeriodicalId":9908,"journal":{"name":"Chemistry and Technology of Fuels and Oils","volume":"68 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2024-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139770133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Shifting from conventional fossil fuels to renewable energy (REN) sources is critical to facilitate sustainable development in China. Compared to coal and oil, REN such as solar and wind energy emit less carbon emissions. Fostering innovation of REN technologies is thus essential for China's green transition. This study aims to analyze the impact of REN technology innovation on China's economic growth using panel data models. The results demonstrate that advancing REN technologies significantly promotes GDP increase in China. Targeted policy incentives must be implemented to accelerate REN technology progression and adoption across the country.
