    The bench slope angle is a eritical structural parameter in the mining of open-pit limestonemines , significantly affecting the mine's safety, stability, and economie benefits. In this study, based onthe new Hoek-Brown strength criterion , the mechanical parameters of the slope were determined as therecommended values for the stability caleulation of the slope rock mass in the open-pit mine. The stabilityof the final end-limit slope was analyzed using FLAc? and Geo-slope software. A comparison and analy.sis of the stability results from the two simulations were performed. Furthermore, considering the lime.stone geological context of the study area, it was ultimately concluded that the final slope angle of theopen-pit bench should be controlled to within 49°, the final bench slope angle should be 65°, the work-ing bench slope angle should be 75°, and the bench height should be 10 meters. The research resultsshowed that the safety factor ( F、) for all open-pit bench slope profiles was greater than 1. 15 , thus meeting the safety grade requirements for Grade lll slope engineering and providing a solid seientific basis andassurance for the safe operation of the mine.

Additionally, we explain how the four teaching methodsused contribute to the achievement of the training target of curriculum-based ideological and political edu-cation. Finally, one of the chapters in the course is used as case study to introduce the process of teachingpractice and summarize the elfectiveness of ideological and political teaching in the course. Practice hasproved that the integration of ideological and political elements into professional courses has the effect ofbeing “easy to understand”, “hands-on”, “interaction motivating” and “critical thinking promoting”.

    The concept of “ green sand and gravel, smart mining” has accelerated the nationwide devel-opment of the sand and gravel industry towards scaling and industrialization. Based on the constructionstandards and requirements for the “ green sand and gravel, smart mine” at Chengxi Stone Quarry in Hua-shan Town, Huadu District, Guangzhou City, this study focuses on building a new intelligent miningplanning technology system for green mines. The technology route is based on 3DMine, self-developedtools, and SuperMlap. On the foundation of using 3DMine for constructing sand and gravel mine models,self-developed tools were used to automate the analysis and generation of mining and stripping plans. Finally, using the B/S architecture, SuperMlap was applied to construct and display a digital twin of the in-telligent mining planning results. Through practical verification in the smart mining project of the granitemine for construction in Chengxi Stone Quarry, Huashan Town, Huadu District, Guangzhou City, the in-telligent mining planning technology system based on 3DMine, self-developed tools, and SuperMap isfound to be compatible with the new green sand and gravel industry structure. It demonstrates high engineering implementation value and feasibility, providing new solutions and reference directions for othermining enterprises in the field of intelligent mining planning.

    'The existing lead-zinc oxide mines in a certain place are characterized by large reserves , lowgrades, complex mineral compositions , and difieulty in exerting economic benelits. To study the reduc-tion and volatilization laws of low-grade zinc oxide ores, the chemical compositions, occurrence states,.and miero-morphologies of raw materials and produets were analyzed one by one, and the thermodynamicbehavior of the reduction roasting process was discussed. The production process flow of ore blending( adding 2596 reduction coal ) , granulation, drying, reduction roasting, and water quenching was deter-mined through experimental exploration. The Zn vapor volatilized during the reduction roasting processwas cooled and collected in the dust, among which the boiler dust contained an average of 29. 49% 2n,the surface-cooled dust contained an average of 42. 94%6 Zn, and the bag dust contained an average of60. 93%6 Zn. XRD was used to conduet comparative analysis on raw materials and slag, and the resultsshowed that the phases of Zn and Pb in the slag disappeared, indicating that the rotary kiln reductionroasting process can elfeetively volatilize Zn and Pb elements from the raw materials. Through materialbalance calculations, it was found that the total recovery rate of Zn reached 97. 18%6 and the reeoveryrate of Ph reached 96. 30%6 during the industrial experiment of rotary kiln reduction roasting, efficientlyachieving the effective utilization of secondary resources.

     In the current era of education digitalization, which is accelerating the construction of a strongeducational nation, the traditional mode of ideological and political theory courses in higher vocational col.leges urgently needs innovation and upgrading. This article analyzes the significance of digital empowermentfor the high-quality development of these courses , emphasizing its role in consolidating the guiding positionof Marxism, its necessity for realizing the great rejuvenation of the Chinese nation , and its inherent require.ment for building a high-level ideological and political work system. The article clarifies the connotation ofthe high-quality development of ideological and political theory courses in vocational colleges and the role ofdigital empowerment in this process. It proposes a “12345" implementation strategy for the high-quality development of digital empowerment in ideological and political education, which includes: adhering to thefundamental task of “ cultivating morality and educating people" , achieving two states- “teachers mustteach with dedication, and students must learn with diligence", reaizing three elfects- “communicatingwith hearts, enlightening minds , and inspiring ambition", strengthening four aspects-“resources , data.platforms, and applications" and connecting five links-“teaching, learning, management, evaluation,and research. " This strategy aims to continuously enhance the ideological, theoretical, and engaging nature of ideological and political theory courses in vocational colleges, while striving to cultivate more skilledcraftsmen and master workers who will undertake the great task of national rejuvenation.

     Based on repeated game theory, this paper proposes a conceptual model to explain the mechanism of contractor hierarchical management thrugh literature analysis and deductive reasoning , supportedby specific case studies. The research shows that contractor hierarchical management is a method of rela-tional govemanee. This form of governanee provides high-quality contractors with the expectation of con-tinued future cooperation through relational commitment , facilitating the establishment of long-term, sta-ble cooperative relationships with high-quality contractors. This, in tum, imprves project cooperationperformance and maxvimizes the interests of the owner. This study provides a theoretical foundation for thepromotion of the contractor hierarchical management model.

    This article is based on the theory of psychological accounts and selects college students fromeight universities in Yunnan Province as the research sample. Using exploratory factor analysis and cross- sectional analysis methods, this study explores the core characteristics and internal influencing factorsof college students’ psychological accounts. The research findings are as follows: First Firstly, collegestudents’ psychological accounts exhibit a three-dimensional characteristic structure : planning, flexibility,and impulsivity. Secondly, gender, grade level, and income are key factors influencing college students'psychological accounts. Males perform better than females in the planning dimension; fourth-yearstudents show higher impulsive consumption tendencies compared to lower-grade students, reflecting themoderating effect of the socialization process. "Thirdly, income level has a dual impact on college students'psychological accounts. lt is negatively correlated with planning and positively correlated with flexibilityand impulsivity, verifying the dynamic reshaping mechanism of the “ Planning Self-Doing Self” powerstructure. This study breaks through the traditional binary opposition paradigm in psychological accountresearch. It reveals a dynamic balance formed through the mediation of flexibility in the three-dimensionalcharacteristics.
