Technical field
Invent a kind of coal wall filling mining top board Monitoring method of the subsidence, it is adaptable to grasp filling mining top board and sink
Fall amount, determines the mining influence district scope of top board.
Background technology
It is big that traditional coal production mode causes hillock to take up an area, and severe environmental pollution and the destruction to soil, from source
Solve environmental problems in mine areas on Tou, reduce soil mining subsidence and destroy, need mine lasting exploit;And filling mining has subtracting
Little ground settlement, improves mining area ecological environment and has resource, and the advantage improving resource recovery meets the requirement of lasting exploit,
Filling mining technology is developed rapidly.
At present coal mine filling mining type mainly has: cash filling is thrown in tunnelling, longwell is general adopts waste filling, longwall full-mechanized mining technique
Waste filling, paste body filling and high*.water packing etc.;Filling mining technology has been ripe exploitation and filling process at non-coal mine,
The system the most perfect to obturator deformation monitoring and method, as patent (application number: 201310082845.5) discloses one
Monitoring method for mechanical deformation of mine filling body;Owing to differing greatly with non-coal mine with coal mining method and technique, but to coal
Ore deposit filling mining top board settling amount, uses the method in existing colliery can not meet requirement, determines the mining influence district model of top board
Enclose and still lack effective means.Strata movement and Overburden Rock Failure that coal mine filling exploitation causes have himself rule, need exploitation long
The method of wall work surface filling mining top board settlement monitoring.
Summary of the invention
For achieving the above object, the technical scheme is that.
A kind of coal wall filling mining top board Monitoring method of the subsidence, by resistance strain type sensor, resistance-strain type
Sensor
Install, the analysis of the monitoring wire laying mode of circuit, Monitoring Data forms.
Resistance strain type sensor is made up of roof and floor fixed disk, resistance-strain type displacement meter, measuring staff and wire.
Resistance strain type sensor installs the altitude mixture control measuring staff length according to roof and floor, and fixed disk is anchored at stable top
On floor rock.
It is a monitoring end face that the wire laying mode of monitoring circuit will often arrange resistance strain type sensor, and resistance-strain type senses
Device parallel connection access tributary wire, offset accesses main traverse line again, and main traverse line is laid in stope drift active workings top board and introduces Control Room;Root
In monitoring host computer, convert displacement according to the strain value of resistance strain type sensor monitoring and judge filling mining top board settling amount.
The Advantageous Effects of the present invention is: provide a kind of coal wall filling mining top board Monitoring method of the subsidence,
Accurately grasp filling mining top board settling amount, determine top board mining influence district scope.

Detailed description of the invention
The present invention will be further described below in conjunction with the accompanying drawings.
The hardware of a kind of coal wall filling mining top board Monitoring method of the subsidence is mainly by resistance strain type sensor
(4), monitoring circuit (5), data analysis software composition.
Resistance strain type sensor (4) is by top board fixed disk (4-2), base plate fixed disk (4-8), strain gauge transducer (4-
5), upper measuring staff (4-1), lower measuring staff (4-6), measuring staff thread segment (4-3), resistance strain type sensor column (4-7) and strain pass
Sense wire (4-4) composition.
Resistance strain type sensor (4) is installed: according to the altitude mixture control of roof and floor upper and lower measuring staff (4-1,4-6) length, will
Roof and floor fixed disk (4-2,4-8) is anchored on stable roof and floor rock.
Monitoring network: determine the maximum stable step pitch of immediate roof according to ore deposit pressure Theoretical Calculation, as first fill area,
Installing resistance strain type sensor (4) in fill area, the spacing between resistance strain type sensor (4) controls at 20-
30m scope, by the conductor in parallel of resistance strain type sensor (4) to monitoring on circuit (5);Resistance strain type sensor (4) it
Between array pitch by filling ore deposit pressure Theoretical Calculation determine.
The wire laying mode of monitoring circuit (5): will often arrange resistance strain type sensor (4) is a monitoring end face, and resistance should
Variant sensor (4) access tributary wire (5-1) in parallel, offset (5-1) accesses main traverse line (5-2), main traverse line (5-2) again
It is laid in stope drift active workings (8) top board and introduces Control Room.
The strain value monitored according to resistance strain type sensor (4) converts displacement in monitoring host computer and judges filling mining
Top board settling amount.
The above, the only detailed description of the invention of the present invention, but the protection domain of invention is not limited thereto, and any ripe
Know the engineers and technicians of the art in the technical scope of the present invention, some conversion can be done, such as filling transducer arrangements
Form, the connected mode of filling sensor, Analysis on monitoring data mode etc., all should be as invading protection scope of the present invention.
Therefore protection scope of the present invention should be as the criterion with the protection domain of claims.
