Description
Technical field
The invention belongs to mining pressure monitoring field, and in particular to a kind of recoverable drilling hole stress monitoring device and
Monitoring method.
Background technology
Mine down-hole exploitation will force surrouding rock stress to be changed into Two dimensional Distribution from original space three-dimensional distribution, that is, cause country rock
Stress is redistributed.Practice have shown that, scientific knowledge simultaneously grasps stress distribution and coverage caused by exploitation, for bump
Prediction and preventing and treating have most important effect.The deep wall rock stress variation caused by exploitation is generally come by borehole stressmeter
Reflection, therefore, the development of borehole stressmeter has practical significance for the monitoring of deep mining rock blast hazard regional stress.
Patent of invention " borehole stressmeter of a hole multimetering " (application number：200710120070.0) it is by hydraulic jack
It is connected with pressure sensor, multiple borehole stressmeters is sequentially placed the precalculated position in installation guide rail, and it is total defeated with same
Oil pipe is connected in parallel the check valve of all borehole stressmeters, is sent into together with guide rail is installed in drilling, it is ensured that sensitive plunger
All the time perpendicular to horizontal plane.Reach to extract out behind precalculated position and guide rail is installed, oiling is raised up to plunger into each oil pressure cylinder
Good rear stopping oiling being contacted with drilling roof, borehole stressmeter starts normal work, realized simultaneously in the interior multiple spot of a drilling
Measurement position is installed and tested.The inventive structure realizes a hole multimetering, reduces workload, saves human and material resources.
But the structure is connected as by rigid hydraulic jack with pressure sensor, because hydraulic jack rigidity is mismatched with drilling country rock,
It is not fairly obvious plus pressure change sometimes, therefore it is difficult to ensure that promptly and accurately monitoring, monitoring effect accuracy needs into one
Step demonstrate,prove, though in addition, the device can the hole multimetering of solid line one, can not recycling, in large area in use, cost
Input is higher.
Patent of invention " flexible mine compression monitoring pressure cushion, monitoring device and its monitoring method " (application number：
201110036482.2) traditional rigid pressure is replaced to rest the head on flexible pressure cushion, with hole wall after this pliable pressure pillow pressurising
It is in close contact, when monitoring coal and rock compression, as long as rock mass somewhat has pressure, so that it may capture, solves read untrue
And loss situation, and the insensitive problem of pressure cushion.The inventive structure timely to pressure change can be caught, but by drilling hole stress
Labyrinth and the influence of site operation complexity are counted, is typically that a borehole stressmeter is installed in a drilling at present, it is impossible to real
More porous monitoring, though in addition, the device can catch the pressure of change in time, can not recycling, in large area
In use, cost input is higher.
The content of the invention
Insensitive for borehole stressmeter of the prior art monitoring, construction is complicated, cost is high, efficiency is low and can not return
The problems such as receipts, it is proposed that a kind of recoverable drilling hole stress monitoring device and monitoring method.
The present invention is adopted the following technical scheme that：A kind of recoverable drilling hole stress monitoring device, including drilling apparatus and its
The connected induction installation of input, outside Fuel Tanking Unit and external memory；
The drilling apparatus includes mining geological drilling rig, the drilling rod being connected with its output end and is connected with drilling rod internal thread
Some feeler levers that mutually splice；It is equidistant on the feeler lever to be provided with 3-4 oval small opening；
The induction installation is included in the oval hydraulic pressure capsule set in oval small opening；On the inwall of the feeler lever side
It is provided with neck, neck and hydraulic jack is installed, hydraulic jack top surface is provided with the card convex for preventing departing from feeler lever,
The fixed block corresponding with card convex is provided with feeler lever neck；The top of hydraulic jack and the thread complete set outside hydraulic pressure capsule
Mutually weldering connects；Thread complete set is internally provided with the pressure sensor of sensing hydraulic pressure capsule pressure；
The outside Fuel Tanking Unit includes electric oil pump station and outside oil conservator；Described electric oil pump station passes through oil inlet pipe
Road is connected with hydraulic jack and hydraulic pressure capsule respectively；The hydraulic jack and hydraulic pressure capsule respectively by go out oil return line with it is outer
Portion's oil conservator is connected；Be provided with described in-line into oil control valve, go out on oil return line to be provided with unidirectionally go out oil control valve；
The external memory is the digital display stress sheet with store-memory function, the input of digital display stress sheet and sense
The drilling rod in device, feeler lever is answered to be connected with the DOL Data Output Line of pressure sensor inside.
Preferred scheme is as follows：
The adjacent spacing of small opening is 50-55cm.Monitoring Data is facilitated to change.
Small opening position is provided with the anticreep hoop for preventing that hydraulic pressure capsule from slipping.High-strength rubber leather bag is filled as pressure sensing
Put, the pressure of change can be caught in time, sensitivity is high, and monitoring effect is good.
A kind of monitoring method of recoverable drilling hole stress monitoring device, step is as follows：
(1) this monitoring device is assembled, feeler lever is sent into and specified at drilling depth by mining geological drilling rig；
(2) open it is all enter oil control valve, start electric oil pump station, hydraulic oil is injected by hydraulic jack in-line
Hydraulic jack, hydraulic jack drives the hydraulic pressure capsule at the top of it to be ejected from oval small opening；Meanwhile, into hydraulic pressure capsule
Inject after hydraulic oil, by pressure conduction to pressure sensor, and be output on digital display stress sheet and shown by DOL Data Output Line
Out；After hydraulic pressure capsule is from the removal of oval small opening, closes on hydraulic jack oil inlet pipe and enter oil control valve；Observe simultaneously
The numerical value change of outside digital display stress sheet, when pressure sensor, which is conducted through next pressure, reaches setting value, closes electric oil pump
Stand, and simultaneously close off and enter oil control valve on hydraulic pressure capsule in-line, into drilling hole stress monitoring state, and record digital display should
Power table numerical value change；
(3) it is to be monitored terminate, open it is all go out oil control valve, then the hydraulic oil in hydraulic pressure capsule and hydraulic jack is through going out
Oil return line flows into outside oil conservator, and hydraulic pressure capsule is retracted into feeler lever with the retraction of hydraulic jack, set back；
(4) mining geological drilling rig is controlled, feeler lever is removed from drilling, completes to reclaim.
Preferred scheme is as follows：
P in step (2)0For 2-3MPa.
After monitoring terminates, it can be shown from digital display stress sheet according to coal-face propulsion and record drilling hole stress
Situation of change, using working face away from hole spacing is monitored as abscissa, drilling hole stress reading is ordinate, draws the relationship of the two bent
The situation of change of line, further analysis and research drilling hole stress.
The present invention has the advantages that：Many feeler lever tandem compounds can be used according to detection requirement, realize a hole
