摘 要: 近年来,钻孔摄像技术因其便捷性和直观性逐渐应用于巷道围岩松动圈实测中,且取得了较好的效果。在此简单阐述钻孔摄像系统的总体结构和工作原理,并以某矿11801工作面顺槽为工程背景,采用钻孔摄像技术对巷道围岩松动圈厚度值进行现场实测,成功获取了围岩松动圈厚度值,为巷道支护设计和稳定性分析提供了依据。
关 键 词: 岩土工程;钻孔摄像;松动圈;现场实测;巷道

Abstract: In recent years because of its ease and intuitive,borehole camera technology is increasingly used in measuring the relaxation zone of surrounding rock and has achieved fairly good results. This paper briefly describes the overall borehole camera system structure and working principle, took 11801 working face of a mine as the engineering background, used borehole camera technology to measure the thickness of relaxation zone of surrounding rock, and successfully obtained the thickness values. The result can be used for the roadway design and provides a basis for stability analysis.
Key words: geotechnical engineering; borehole camera; broken zone; spot test; roadway
