Energy releasing and buffering real-time monitoring method for disaster of surrounding rock in underground space

Abstract

The invention provides an energy releasing and buffering real-time monitoring method for a disaster of surrounding rock in underground space and belongs to the technical field of safety detection and monitoring of mining and geotechnical engineering. The method is characterized by adopting a monitoring system and comprising the following steps: step 1, fixing anchor bolts (1); step 2, mounting a surrounding rock inducing and buffering mechanism; step 3, mounting a surrounding rock displacement acquisition device; step 4, monitoring displacement of the surrounding rock (7); step 5, executing step 6 if the displacement of the surrounding rock (7) exceeds a preset threshold or meets a precursor mode, and executing step 4 otherwise; step 6, executing step 7 if the surrounding rock (7) has the probability of a surrounding rock disaster, and executing step 9 otherwise; step 7, predicting the range of the surrounding rock disaster; step 8, releasing the early warning level of the surrounding rock disaster; step 9, performing alarming by a master control computer. With adoption of the method, energy releasing, buffering and displacement of the surrounding rock are monitored, and the probability of accidents is reduced.

Description

technical field [0001] The invention provides a real-time monitoring method for energy release and buffering of surrounding rock disasters in underground space, belonging to the technical field of mining and geotechnical engineering safety detection and monitoring. Background technique [0002] Surrounding rocks in the underground space have hazards such as slabs, roof caving, water inrush, and rockburst dynamic disasters, which pose a direct threat to staff and equipment, affect the progress of the project, and cause support failure and even earthquakes. Bolt support has become a main form of mine roadway and other underground engineering support in all countries in the world, and the long-term 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, the frequency and intensity of surrounding rock damage are getting higher and higher, engine...

AI Technical Summary

Problems solved by technology

At present, the energy release and buffering methods for the surrounding rock anchorage area mainly focus on the use of bolt buffer trays, energy-absorbing deformable trays, large-deformation energy-absorbing bolts, and constant-resistance large-deformation bolts. The above methods cannot be well realized at the same time. Buffering and energy release functions, not to mention the monitoring of surrounding rocks
