摘要
岩体结构识别和力学参数表征是岩石力学领域的基础问题,是金属矿山开采设计的重要依据。由于天然岩体结构的复杂性,岩体力学参数确定一直是岩石力学的难点。随钻测量技术作为一种便捷、快速的原位连续测量方法,能够利用钻孔过程中钻头的动力学响应,评价岩体结构特征和力学性质,配合钻爆法施工,具有不可比拟的优势。国内外学者进行了大量的研究工作,取得了许多研究成果。回顾了20世纪70年代至今的随钻测量研究成果和最新研究进展,从随钻测量技术研究的相关试验设备、随钻测量表征岩体结构、随钻测量表征岩石强度三方面进行了较系统地综述,分析了已有研究工作存在的不足,最后结合课题组的工作和认识,指出了随钻测量技术可能的发展方向,为该技术的后续应用与研究提供参考。
The rock mass structure characterization and mechanical parameters determination are hot issue in the field of rock mechanics and serve as crucial basis for metal mining design.How to determine the mechanical parameters of rock mass has always been a challenging task in the field of rock mechanics due to the complexity and spatial variability of natural rock mass structures.Measurement while drilling(MWD)technology provides an easy and rapid in-situ testing method that enables the assessment of rock mass characteristics and strength during the drilling process by utilizing the response of the drill bit,and the MWD has incomparable advantages combined with drilling and blasting in the mining industry.Extensive studies have been conducted on MWD both domestically and internationally,leading to significant achievements.This paper provides a comprehensive overview of the MWD research findings from the 1970s to the present and recent advances in MWD research,including the test facility for MWD research,rock mass characterization while drilling,and rock strength estimation while drilling,and the limitations of the MWD research are also analyzed.Finally,based on the studies and findings of our group,the possible development directions for MWD are pointed out,providing a reference for future research and application of the technology.
