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

Embodiment Construction

[0032] Figure 1~3 It is the best embodiment of the present invention, below in conjunction with attached Figure 1~3 The present invention will be further described.

[0033] A real-time monitoring method for energy release and buffering of surrounding rock disasters in underground space, including a monitoring system, such as figure 1 As shown, the monitoring system includes: a bolt 1 fixed in the surrounding rock 7, a movable tray 6 is set on the part of the bolt 1 outside the surrounding rock 7, and a compression spring 5 is installed on the outside of the movable tray 6. The outer side of the spring 5 is equipped with a fixed tray 4, and the fixed tray 4, the compression spring 5 and the movable tray 6 are fixed on the surface of the surrounding rock 7 by the fastening nut 2 on the outer side of the fixed tray 4, and the compression spring 5 is guaranteed to be in a compressed state .

[0034] A stay cord displacement sensor 3 is installed between the fixed tray 4 and ...

Abstract

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. It is characterized in that it includes a monitoring system and the following steps: step 1, fixing the anchor rod (1); step 2, installing the surrounding rock induction buffer mechanism; step 3, installing the surrounding rock displacement acquisition device; step 4, performing the surrounding rock (7) Displacement monitoring; step 5, when the displacement of the surrounding rock (7) exceeds the preset threshold or meets the precursory mode, go to step 6, otherwise go to step 4; step 6, there is a possibility of a surrounding rock disaster in the surrounding rock (7) , go to step 7, otherwise go to step 9. Step 7: Forecast the range of surrounding rock disasters; Step 8: Release the early warning level of surrounding rock disasters; Step 9: Alarm by the main control computer. Through the method, the monitoring of energy release, buffering and displacement of the surrounding rock is realized, and the possibility 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...
