Description
Technical field
This utility model relates to coal mine roadway wall rock loosening ring field, particularly a kind of device dynamically changed for auxiliary monitoring wall rock loosening ring.
Background technology
The breakage in installation of the underground space initial equilibrium conditions of country rock, the radial stress of cavern's periphery disappears, tangential stress increases severely, and country rock carries out stresses re-distribution.Along with cavern excavation, cavern's periphery rock mass initially enters mecystasis and then destroys, stress shifts to rock mass deep, surrounding rock failure scope expands gradually, until surrouding rock stress less than or equal to rock mass strength, forms new balance, destroy and just terminate, cavern's periphery forms a crushed zone, is referred to as relaxation zone.Wall rock loosening ring is ubiquitous objective physical mechanical state in the Geotechnical Engineering of deep, and it is most important on the impact of underground engineering stability.Wall rock loosening ring support theory has extensively been admitted by engineering circles and has accepted, after adit digging, wall rock loosening ring is formed, but by the impact adopted or other caves excavate, the relaxation zone of country rock can change, such as depth down, expanded range, local crush, particularly some deep soft rock chambers, owing in time the part of wall rock loosening being carried out supporting and making chamber destroy.The method now relaxation zone of country rock being monitored has a lot: no matter is single hole or diplopore method of testing, makes a call to a secondary aperture and can only test once, again tests and also need again to punch.Therefore, a kind of simple and practical device dynamically changed for auxiliary monitoring wall rock loosening ring is developed imperative.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the purpose of this utility model is just to provide a kind of device dynamically changed for auxiliary monitoring wall rock loosening ring, can effectively solve monitoring wall rock loosening ring and want ' one survey one hole ' or ' one survey holes ', and the problems such as dynamic monitoring can not be carried out.
The technical scheme that this utility model solves is, monitors system including New Anchor Cable, New Anchor Cable section and wall rock loosening ring, and described New Anchor Cable has anchor cable head and anchor cable afterbody；New Anchor Cable section has single solid steel twisted wire and hollow steel twisted wire；Wall rock loosening ring monitoring system has roadway surrounding rock, New Anchor Cable is anchored in the middle of roadway surrounding rock, acoustic emission module and sound wave receiver module are put into the hollow steel twisted wire of New Anchor Cable and can move freely, and video-stream processor is connected with acoustic emission module and sound wave receiver module.
This utility model is a kind of device dynamically changed for auxiliary monitoring wall rock loosening ring, when Exploring Loose Rock Country in Tunnels is monitored, acoustic emission module is put into wherein in an anchor cable, acoustic receiver module is put in the anchor cable that another root is adjacent, these modules are connected with outside video-stream processor, and its degree of depth in anchor cable can arbitrarily regulate, by regulating the degree of depth of acoustic emission module and receiver module, the loosening situation of the country rock of different depth can be recorded, can record in working face mining process by changing the distance of acoustic emission module and sound wave receiver module and work surface, the work surface influence degree to roadway surrounding rock around.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
This utility model includes the single solid steel twisted wire of outside and internal hollow steel twisted wire.Hollow steel twisted wire 9 is in the inside of New Anchor Cable, and single solid steel twisted wire 8 is enclosed in hollow steel twisted wire 9 around；Anchor cable head 5 and anchor cable afterbody 7.Wall rock loosening ring for specifically used method is described is monitored system and is included roadway surrounding rock 1, acoustic emission module 3, acoustic receiver module 2, video-stream processor 4.
In order to ensure result of use, described single solid steel twisted wire 8 and hollow steel twisted wire 9 are intended to select high strong elastic steel strand wires.
Described single solid steel twisted wire 8 and hollow steel twisted wire 9 are that New Anchor Cable 6 processing itself has.
Described acoustic emission module 3 and sound wave receiver module 2 are that video-stream processor 4 has itself.
Described hollow steel twisted wire 9 has certain thickness.
The described New Anchor Cable 6 in wall rock loosening ring monitoring system is anchored in roadway surrounding rock 1.
Described acoustic emission module 3 and the sound wave receiver module 2 position in New Anchor Cable 6 can move freely.
In order to reach result of use, selected acoustic emission module 3 and the diameter of sound wave receiver module 2 are less than the diameter of New Anchor Cable 6 boring steel strand wires 9.
During this utility model operation, New Anchor Cable 6 is anchored in the middle of roadway surrounding rock 1 as normal anchor cable, acoustic emission module 3 is put in the middle of the boring steel strand wires 9 of a wherein New Anchor Cable 6, acoustic receiver module 2 is put in the middle of the boring steel strand wires 9 of an adjacent New Anchor Cable 6, acoustic receiver module 3 and the sound wave transmitter module 2 depth adjustable in hollow steel twisted wire 9, in order to the wall rock loosening ring of different depth is monitored.
This utility model simple in construction, required expense is relatively low, wants ' one survey holes when can efficiently solve monitoring wall rock loosening ring ' or ' one survey one hole ', and hole and can not reuse, it is impossible to realize the problems such as dynamic monitoring.This device suitability is relatively strong, and the place that common anchor cable is suitable for, this anchor cable is all applicable, has the stronger suitability.
