It is of great significance to study the reasonable position of mining roadway under strip coal pillar for increasing the stability of mining roadway, reducing the waste of resources, and realizing the safety production of working face. Based on the research background of the working face under the strip coal pillar in Jinqiao Coal Mine of Jining, Shandong Province, through theoretical analysis, similar material simulation experiment, and numerical simulation experiment, the stress distribution law, plastic failure range, and rationality of coal pillar setting in different width sections are systematically studied. Finally, the tailentry of working face is determined at the position of 5 m from the bottom of strip coal pillar to 1308 goaf. During the mining period of 1310 working face, the peak value of side abutment pressure is at the position of 3∼4 m; beyond 25 m in front of the coal wall, the deformation of the surrounding rock on the tailentry surface is small. After entering the advanced support section, the deformation of the two sides is mainly longitudinal crack expansion and local shallow small flakes; however, the roof is complete and stable. Therefore, the selection of tailentry location and coal pillar width has played a good role. The research results of this study can provide some reference for similar mine with similar geological and production technical conditions.
At present, there are indeed many problems in the training of upgraded talents among e-business students such as unclear training objectives and characteristics, as well as the lack of classified guidance and its corresponding mechanism. Therefore, there is a need for optimization and upgrading of faculties in which active research should be conducted on these issues. Through various measures to counter the challenges faced in the training of upgraded talents in e-business education based on the student-oriented ideology and advantages of universities, the environment needs to be constantly optimized while improving their levels, designing effective countermeasures, and having firm ideological beliefs. This article strives to educate senior e-business innovative talents in line with the needs of enterprises, continuously promote the integration of industry and education, as well as commit to contributing toward a comprehensive and healthy development of the e-business industry as well as social progress.
Based on credit bank, the “1+X” certificate system is a “flyover” for learners to interchange between the academic and vocational education. It is a significant innovation to promote high-quality vocational education development and enhance the influence of national vocational education. Vocational colleges can implement “1+X” certificate system via the credit bank and in turn, the popularization of the “1+X” certificate system would enrich and improve the former. China’s development of the credit bank and the existing research on the “1+X” certificate system are analyzed to look for a way in the collaboration of credit bank and the “1+X” certificate system. The firm collaboration as well as the connection and optimization between government, schools, and enterprises as one body form a new talent training mode with the “1+X” certificate system that integrates academy and certificates as well as involving both, schools and enterprises according to China’s credit bank concept.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
