Description
Technical field
The present invention relates to mine and tunnel safety monitoring technical field, particularly relate to a kind of recyclable
Formula country rock ruptures monitoring acoustic emission sensor erecting device and method.
Background technology
Underground passage driving all needs to excavate deep rock mass or explosion with ore extraction, and
The excavation of rock mass and explosion all can produce strong disturbance to protolith, cause tunnel or boring around
Rock mass produces phenomenons such as rupturing.In engineerings such as Mine Tunnel Construction, chamber and deep tunnel excavations
In, deep tunnel and tunnel are by Excavation blasting disturbance, or goaf is given a shock disturbance etc.,
All may produce the dynamic disasters such as rock burst, destructive power is very big, serious threat down-hole or tunneling operation
Personnel and equipment safety, bring hidden danger to the safety in production in mine and tunnel.Acoustic emission monitor(ing) skill
Art and equipment can monitor the micro rupture signal within rock mass in real time, before catching dynamic disaster cause calamity
Million information, can be predicted forecast through signal processing analysis to the disaster such as rock burst, bump.
Traditional country rock ruptures monitoring acoustic emission sensor and is mostly installed on country rock surface, not only can
Disturbed by ambient noise, the most often touched off damage, impact prison by workmen or machinery
Survey effect.Another kind of mounting means is that sensor is installed on bore inner, although avoid with
Upper drawback, but use which that sensor will be caused to reclaim, cause the wasting of resources.
Down-hole or tunnel monitoring sensor are close to country rock wall mostly or it is towards along boring at present
Hole is axially installed, and sensor is mostly unilateral transducer, and this installation method is to boring
The acoustic emission signal reception that periphery ruptures is more weak, there is the problems such as signal recognition degree is low.So
And, the dynamic disaster such as country rock rock burst or bump betides country rock near surface mostly, so should
Focus on and country rock near zone acoustic emission signal is monitored.Other down-hole or tunnel monitoring pass
Sensor is installed patent such as 104407059A, 204086563U, 103558630A etc. and is all only capable of
At bore inner, one sensor is installed, owing to not coupling contact, the signal of sensor are transmitted across
The interference of journey etc. may cause sensor failure or the problem such as signal recognition degree is low.
For avoiding the deficiency of tradition acoustic emission sensor installation method, one is needed to be applicable to down-hole
Or recoverable and country rock near field can be caused calamity signal and effectively receive in the environment such as tunnel
Acoustic emission sensor installation method and device.
