Abstract: In recent years, the reduction of shallow resources has increased the demand for deep resources. The deep engineering exceeds 1 kilo-meters level has become more normal. The deep engineering of Jinchuan No. 2 Mine is deeper than 1000 m, facing the safe production issues of deep mining. The zonal disintegration phenomenon of the surrounding rock in deep roadway is a research hotspot of deep engineering research. In order to monitor the zonal disintegration phenomenon in the deep tunnel of metal mines, we selected six sections in the 700m horizontal roadway of Jinchuan No.2 Mine, and arranged two monitoring points in each section. By using the surrounding rock loosening zone test machine, we monitored the rupture zone of the surrounding rock and we found the phenomenon of zonal disintegration of surrounding rock in deep engineering. The monitoring results show that there are zonal disintegration parts in the monitored section. The thickness of the rupture zone decreases with the distance from the surface of the roadway, and the fragmentation degree decreases and the integrity increases. The rediscovery of the zonal disintegration is of great significance for the stability analysis of the surrounding rock in deep roadway and the improvement of support design.
