Technical field
The present invention relates to a kind of accurate monitoring devices of roof delamination.Belong to wall rock's level technical field, is particularly suitable for lane
Road country rock
Monitoring.
Background technology
Roadway surrounding rock condition is increasingly complicated with the increase of coal mining depth.Under Mining in Deep-lying Conditions, due to geology ring
The deterioration in border, mining induced stress are dramatically increased with tectonic stress, and roadway surrounding rock shows large deformation feature.Roadway roof absciss layer phenomenon
It is more common.After tunneling a tunnel in coal seam, tunnel cap rock layer is exactly coal mine roof plate, and roof delamination refers to back
In rock stratum a little and the relative shift put of certain in its top certain depth rock stratum, roof delamination cross conference cause top plate emit it is useful
Therefore generation, therefore roof delamination is monitored in time can grasp roof delamination data at the first time, done conducive to roof conditions
Go out accurate prediction.When roof delamination, fall of ground accident can be caused.Although roof delamination monitoring instrument used at present has
Simple installation, it is cheap the advantages that, but its measuring point is few and needs artificial underground monitoring reading, cannot measure specific separating location
Deng be difficult in real time monitoring roof delamination situation, device insecure result is installed and generates deviation, monitoring range is small, and measurement error compared with
Greatly.Existing roof delamination monitoring instrument is only capable of the maximum roof delamination monitored within the scope of twice of rock-bolt length when roof delamination
Situation can not be monitored roof delamination when the practical absciss layer range of top plate is larger；In addition, existing roof delamination monitoring
Instrument is all manual site's monitoring, and poor continuity, underground monitoring error is big, cannot grasp roof delamination situation in real time.The present invention carries
A kind of roof abscission layer monitoring device has been supplied, roof delamination situation can accurately have been monitored by the device, monitoring range is big, Gong Renwu
Field monitoring is needed, the size of specific separating location and absciss layer amount can be monitored, ensures continuity, the accuracy of monitoring, realization pair
The effect of roof delamination situation accurate perception.
Invention content
It is an object of the invention to overcome the shortcomings of technology in existing roof delamination monitoring instrument, a kind of roof delamination is provided
Monitoring device, feature are accurately to monitor, and reasonable design is adaptable and easy to install and use.
To achieve the goals above, specific embodiments of the present invention are as follows：A kind of accurate monitoring device of roof delamination, packet
Inside and outside sleeve is included, outer sleeve is made of two halves sleeve.The outer sleeve is formed by two and half, is arranged in the inner surface of outer sleeve

Cylinder can lengthen, fixed with adhesive tape etc. at sleeve connection, to realize the effect monitored on a large scale.
The accurate monitoring device of the roof delamination is put among top plate drilling as a preferred technical solution, the housing
Gap slip casting blocks between cylinder and drilling, keeps outer sleeve cemented together with roof strata.The outer sleeve inner surface is disposed with
Fixing screws, the position of the fixing screws, which is located at, estimates roof delamination position both ends, and cloth is determined according to absciss layer number is estimated
Set fixing screws number；The internal parallel conducting wire of several different lengths, every internal parallel are disposed between fixing screws
Conducting wire has resistance series connection；Between fixing screws the length of longest internal parallel conducting wire subtract the spacing between fixing screws be exactly can
The maximum value of the roof delamination amount enough monitored；Length difference is designed according to certain gradient between internal parallel conducting wire, and inside is simultaneously
Connection wire count can be increased and decreased according to precise requirements, and internal parallel wire count is more, and gradient difference is smaller, roof delamination feelings
Condition is more accurate, i.e. the maximum value ÷ internal parallel wire counts of the roof delamination amount for roof delamination amount accuracy=can monitor.
Described to have the concatenated internal parallel conducting wire of resistance parallel with one another, sys node is at fixing screws.Phase is arranged according to required precision
The internal parallel conducting wire for answering number determines the length of longest internal parallel conducting wire according to the size of maximum absciss layer amount.When top plate from
When layer, crack increases, and outer sleeve is broken with roof delamination, and the internal parallel conducting wire between fixing screws is drawn by root
Disconnected, to make circuit equivalent resistance increase, loop current reduces, and certain electric current corresponds to the corresponding indicator light of indicator lamp groups.It can
To indicate that situation knows roof delamination situation according to indicator light, to play the role of monitoring roof delamination situation.According to inside
Parallel conducting wire length gradient difference and the time interval being pulled off by root can find out roof delamination rate size, i.e. roof delamination
The time interval of rate=internal parallel conductor length gradient difference ÷ indicator lights transformation.The inner sleeve is made of hollow tube, institute
The inner sleeve stated has trepanning, external series conducting wire to be opened across inner sleeve by the gap between inside and outside sleeve every a distance
Hole stores external series conducting wire in the hollow barrel dliameter of inner sleeve into inside inner sleeve, is stored in inner sleeve when roof delamination
External series conducting wire is drawn out, and avoiding external series conducting wire from being pulled off leads to line broken circuit.
The inner sleeve is placed in outer sleeve as a preferred technical solution, after the completion of outer sleeve inner surface arrangement, outer
Sleeve is merged into complete sleeve.
Beneficial effects of the present invention：The accurate monitoring device of this roof delamination play roof delamination is accurately monitored, absciss layer
Position monitoring, the roof separation value monitor, the monitoring of absciss layer rate, absciss layer number monitors, installation is simple, device will not slide production in drilling
Raw error is not necessarily to manual site's monitoring and other advantages.Power supply adapts to coal mine condition, belongs to essential safe type；Roof delamination situation root
It is very clear according to the indicator light instruction situation in indicator lamp groups, it is convenient accurate.It realizes and is monitored without manual site, accuracy of detection
It greatly improves.
