Deep detection system and detection method of deep lane surrounding rock partitions

Abstract

The invention discloses an in-site detection system of zonal disintegration of deep roadway surrounding rock masses. The system comprises a multipoint displacement meter, a drilling television probe and a color monitor, wherein measuring points of the multipoint displacement meter are arranged in displacement meter mounting holes in a roadway monitoring section and led out of drilling holes respectively through thin steel wire ropes, so that deformation of the surrounding rock masses in the positions of different depths of the drilling holes; and the drilling television probe is arranged in a television probe mounting hole in the roadway monitoring section and connected with the color monitor. According to the in-site detection system of zonal disintegration of the deep roadway surrounding rock mass, observation methods such as multipoint displacement detection, mine drilling television imaging, specific resistance measurement and the like and a geological radar detection technology are adopted for mutual supplementation and learning from each other, so that a reliable data result can be obtained, the foundation is provided for selecting a reasonable support mode for the deep roadway support, and the system is particularly suitable for evaluating the zonal disintegration range and damage degree of the surrounding rock masses and confirming relative support measures in deep underground construction.

Description

technical field [0001] The invention relates to the technical field of deep roadway surrounding rock detection, in particular to an on-site detection system and detection method for deep roadway surrounding rock partition rupture. Background technique [0002] During the excavation of underground engineering, such as roadways, tunnels, caverns and workplaces, the stress balance state of the original rock is destroyed, and the redistribution of stress makes the surrounding rocks in different damage and stress states. Therefore, underground engineering must be carried out after excavation. Corresponding support, at present, there are many roadway support methods, such as bolt support, anchor shotcrete support, anchor shotcrete net support, anchor cable support, masonry support, metal arch support, material support, etc. Stone support, reinforced concrete support and joint support between various supports, etc. In deep coal mine mining, roadway support also adopts anchoring and...

AI Technical Summary

Problems solved by technology

[0003] In the actual process of deep roadway surrounding rock partition fracture test, because most of the single observation method or detection technology is used, the data is often inaccurate or invalid due to the defects, deficiencies and human factors of a certain method or technology, so that the test results cannot be confirmed. less than expected
