Description
Technical field
The present invention relates to coal mining fields, and in particular to a kind of coal mine down-hole tunnel deformation monitoring method.
Background technique
Coal mine down-hole tunnel is by action of underground, and inducement is complicated, and influence factor is more, the deformation that mostly occurs, country rock convergence
Equal strata behaviors.Previous monitoring means is mostly single method, it is difficult to surrouding rock deformation rule is more comprehensively grasped, thus
Roadway support design is based on insufficient grounds, so the roadway deformation monitoring method of more suites of measure is used to provide more for roadway support design
Accurate data are added to be of great significance.
Summary of the invention
Technical problem to be solved by the present invention lies in view of the above shortcomings of the prior art, provide a kind of underground coal mine lane
Road deformation monitoring method.
To solve the above problems, the present invention proposes a kind of coal mine down-hole tunnel deformation monitoring method, the specific steps are as follows:
(1) numerical simulation analysis is tentatively unfolded to roadway deformation；(2) convergence monitoring is carried out to drift section；(3) top plate is carried out
Delamination monitoring；(4) monitoring is pried through using drilling to tunnel；(5) anchor pole, anchor cable stress in tunnel are monitored；(6) right
Result out obtained as above carries out comprehensive analysis.
The step (1) method particularly includes: the geologic information of collection research regional roadway establishes model, carries out numerical value
Sunykatuib analysis.
The step (2) requires are as follows: the production of ring of convergence uses gasket, is vertically welded on anchor rod pallet board, is fixed on anchor
It on bar, is measured with digital readout convergence meter, the measurement accuracy of convergence gauge is 0.01mm.
The roof delamination monitoring of the step (3) is monitored using 9 roof separation indicators, roof separation indicator buried depth
Respectively 8m, 7.5m, 7m, 5m, 2.8m, 2.5m, 2m, 1.5m, 1.0m.
The step (4) is helped using air drill in back and two and base angle corresponding position beats moving-coil monitoring holes, with brill
Hole endoscope carries out prying through record in hole, and carries out data analysis.
The step (5) is monitored anchor pole, anchor cable force-bearing situation using anchor pole, anchor dynamometer.
The step (6) analyzes above step measured result, obtains roadway deformation monitoring result, is roadway support
Design provides foundation.
Compared with the prior art, the present invention has the following advantages:
Operation of the present invention is simple, easily implements；It, can be more detailed from theoretical values sunykatuib analysis to live practical more means monitorings
The data for obtaining coal mine down-hole tunnel deformation, to provide more accurate foundation for design of its support.
Invention is further described in detail with reference to the accompanying drawings and examples.
Detailed description of the invention
Fig. 1 is flow chart of the present invention.
Specific embodiment
Example is to carry out deformation monitoring, according to Fig. 1, a kind of coal mine down-hole tunnel deformation monitoring to certain mine underworkings
Method, the specific steps are as follows: (1) numerical simulation analysis is tentatively unfolded to roadway deformation；(2) convergence prison is carried out to drift section
It surveys；(3) delamination monitoring is carried out to top plate；(4) monitoring is pried through using drilling to tunnel；(5) to anchor pole in tunnel, anchor cable by
Power is monitored；(6) comprehensive analysis is carried out to result out obtained as above.
The geologic information of step (1) collection research regional roadway establishes model, carries out numerical simulation analysis.
The production of step (2) ring of convergence uses gasket, is vertically welded on anchor rod pallet board, is fixed on anchor pole, uses
