International Journal of Mining Science and Technology 2024年第1期34卷 65-76页

The technology of drilling tests makes it possible to obtain the strength parameter of rock accurately in situ. In this paper, a new.rock cutting analysis model that considers the influence of the rock crushing zone(RCZ) is built. The formula for an ultimate cutting force is established based on the limit equilibrium principle. The relationship betw.en digital drilling parameters(DDP) and the c-φ parameter(DDP-cφ formula, w.ere c refers to the cohesion and φ refers to the internal friction angle) is derived, and the response of drilling parameters and cutting ratio to the strength parameters is analyzed. The drillingbased measuring method for the c-φ parameter of rock is constructed. The laboratory verification test is then completed, and the difference in results betw.en the drilling test and the compression test is less than 6%. On this basis, in-situ rock drilling tests in a traffic tunnel and a coal mine roadw.y are carried out, and the strength parameters of the surrounding rock are effectively tested. The average difference ratio of the results is less than 11%, w.ich verifies the effectiveness of the proposed method for obtaining the strength parameters based on digital drilling. This study provides methodological support for field testing of rock strength parameters.

在中国教育博士专业学位培养模式设置15周年之际,全面认识其改革的历史进程、内在机制与发展方向等问题,对促进教育博士专业学位研究生教育高质量发展具有重要意义。基于制度变迁理论构建中国教育博士专业学位培养模式改革的分析框架,认为中国教育博士专业学位培养模式经历了酝酿奠基、试点实施和全面推广三个时期。在这过程中,它遵循着特定的改革机制。这种机制固然有其优势,但现阶段遇到了困境:三个主体的位置有待进一步理顺,强制力和诱导力的程度有待进一步提高,路径依赖的窠臼有待进一步突破。展望未来,教育行政部门、教指委和培养单位三主体需各就其位,凝聚改革最大合力;既要增强强制性改革的强制力,又要提升诱致性改革的诱导力;坚持连续性渐进式改革,推动重点领域取得突破。
