Abstract

The invention relates to a bolt-based underground space surrounding rock disaster resistivity real-time monitoring method and belongs to the mining and geotechnical engineering safety detection and monitoring technical field. According to the method, an underground space surrounding rock disaster resistivity real-time monitoring device is set and includes a power supply electrode, a measuring electrode, an electrical prospecting apparatus, a bolt and a main control computer; the main control computer is connected with the electrical prospecting apparatus; the power supply electrode and the measuring electrode are connected with the electrical prospecting apparatus through conductors; and the power supply electrode and the measuring electrode are connected with the bolt at an underground space surrounding rock monitoring area. According to the bolt-based underground space surrounding rock disaster resistivity real-time monitoring method, the bolt is adopted as a conductor to monitor the resistivity of an anchorage zone and surrounding rock; and the stability of the surrounding rock and anchorage zone is monitored according to the change of the resistivity. The method has the advantages of no damage to the surrounding rock, high accuracy, wide application range and the like.

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...
