Abstract
The invention discloses a kind of method with man-made explosion as vibration signal inverting coal mine work area stress distribution, including data acquisition, data processing, data interpretation procedure：In the haulage gate side placement sensor of coal mine work area, track crossheading is surveyed arrangement and is blown out a little, blows out a little corresponding with sensing station；One sensor record reference signal is separately installed, the start record signal when blowing out or weight is tapped；Log file is opened with Velocity Inversion software, observation system is set up, man-made explosion point and sensor coordinates are input into, the then time of signal is received with software tags sensor, calculate all rays；The gridding on three dimensions by coal mine work area, velocity of wave in each grid is set as constant, lists every ray through the length equation of each grid, is finally inversed by the velocity amplitude of each grid, power function relationship is had according to shock wave velocity of wave and stress, the stress information of coal mine work area is obtained.The present invention show that ripple ratio is more accurate by the ore deposit shake velocity of wave that draws of event.
Description
Technical field
The present invention relates to a kind of method of vibration signal inverting stress, more particularly to one kind is with man-made explosion as vibration signal
The method of inverting coal mine work area stress distribution.
Background technology
Impulsion pressure is the result of Stress relief after coal mining, the in-built real-time detection of coal-face, is point
The basis of analysis prediction impulsion pressure.Research shows that the velocity of wave of shock wave increases with the increase of stress, therefore in coal mine work area
The stress intensity in portion can reflect that velocity of wave can be when walking and then anti-according to shock wave by measuring the velocity of wave size of shock wave
Drill and obtain.Shock wave can be obtained by two kinds of different excitaton sources：Controllable source and ore deposit shake.Current colliery shock wave monitoring method base
All it is monitoring ore deposit shake event in sheet, event inverting working face stress distribution is shaken according to ore deposit.The ore deposit caused by recovery activity shakes event,
Due to not knowing initial time and position, the velocity of wave that vibration signal is finally inversed by is often inaccurate.
The content of the invention
The technical problems to be solved by the invention are to overcome prior art defect, there is provided one kind being capable of real-time detection colliery
Working face, the degree of accuracy for improving inverting working face inside velocity of wave, are vibration signal inverting coal mine work area stress with man-made explosion
The method of distribution,
In order to solve the above-mentioned technical problem, the man-made explosion that the present invention is provided is vibration signal inverting coal mine work area stress distribution
Method, including data acquisition, data processing, data interpretation procedure are specifically included：
（1）Data acquisition：In the haulage gate side placement sensor of coal mine work area, track crossheading is surveyed arrangement and is blown out a little or weight
Beating point, blows out a little or weight beating point is corresponding with sensing station；One sensor record reference signal is separately installed, when putting
Start record signal when big gun or weight are tapped, often puts a big gun or weight is tapped and once recorded in one file, the text of record
Part number is identical with the number of times that man-made explosion shakes；
（2）Data processing：Open log file with Velocity Inversion software, set up observation system, input man-made explosion point coordinates and
Sensor coordinates, the then time of signal is received with software tags sensor；Velocity Inversion software is according to man-made explosion point coordinates
And sensor coordinates, calculate all rays of coal mine work area；
（3）Data are explained：The gridding on three dimensions by coal mine work area, the velocity of wave in each grid is set as constant, row
Go out every ray through the length equation of each grid, solving equations are finally inversed by the velocity amplitude of each grid, obtain coal mine working
The velocity image in face；There is power function relationship in the velocity of wave according to shock wave, you can obtain the stress point of coal mine work area with stress
Analysis information.
The beneficial effects of the present invention are：It is of the invention blow out a little or weight beating point for artificial excitation controllable source,
I.e. known focus position, the velocity of wave that thus ripple ratio inside inverting coal mine work area is finally inversed by according to the vibration signal that ore deposit shakes event
It is more accurate result.
Brief description of the drawings
Fig. 1 is the arrangement schematic diagram of coal mine work area of the invention；
