Abstract

A bolt-based real-time monitoring method for resistivity of surrounding rock hazards in underground space belongs to the technical field of mining and geotechnical engineering safety detection and monitoring. Set up a real-time monitoring device for surrounding rock disasters in underground space, including power supply electrodes, measuring electrodes, electrical instruments, anchor rods and a main control computer. Connection, the power supply electrode and the measurement electrode are respectively connected with the anchor rod in the surrounding rock monitoring area of ​​the underground space. The anchor rod is used as a conductor to monitor the resistivity of the anchorage area and the surrounding rock, and the stability of the surrounding rock and the anchorage area is monitored according to the change of the resistivity. It has the advantages of no damage to surrounding rock, high accuracy and wide application range.

Description

technical field [0001] A bolt-based real-time monitoring method for resistivity of surrounding rock hazards in underground space belongs to the technical field of mining and geotechnical engineering safety detection and monitoring. Background technique [0002] Surrounding rocks in the underground space have dangers such as slabs, roof caving, water inrush, and rockburst dynamic disasters, which not only cause support failure, affect the progress of the project, and even cause earthquakes, posing a direct threat to staff and equipment. Bolt support has become a main form of mine roadway and other underground engineering support in various countries in the world, so the stability of the bolt anchorage area is particularly important. With the continuous increase of underground space development and mining depth, the ground stress is getting higher and higher, which makes the surrounding rock damage frequency and intensity higher and higher, engineering disasters are becoming m...
