The geologic agent that has the safe and efficient production of many influences in the mine working face exploitation process; Comprise that mainly the tunnel discloses the extension situation in tomography, squeeze district; And developmental conditions such as potential fault, karst collapse col umn in the face, it is meticulous more that the comprehensive mechanical coal mining degree is constructed the degree of detecting more in the high request opposite.Therefore, fully-mechanized mining working must carry out physical prospecting before back production surveys, and investigates thoroughly internal structure and off-note thereof, guarantees the safe and efficient production of coal mine work area.
At present, more to the in-built method for surveying of fully-mechanized mining working, mainly comprise contents such as electrical method CT, earthquake CT, VOICE FREQUENCY ELECTRIC PERSPECTIVE TECHNIQUE technology, radiowave perspective technology.In these methods, electrical method CT and earthquake CT need manpower more, and it is long to take the work on the spot time, and field requirement is coordinated in many ways, and running program is complicated, normally uses in the complex structure district.And radiowave perspective technology be contactless detection, and execute-in-place is simple, and resolution characteristic is good, therefore at home and abroad gains great popularity and obtains fast-developing and application.But also there is limitation in existing radiowave perspective technology at data acquisition modes, and work on the spot is wasted time and energy, and labour intensity is big, is unfavorable for that detecting of comprehensive mechanical coal mining workplace requires and development.Mostly on-the-spot coal mine work area is that strike length is long, and what have reaches 2-3km, and it is long that radiowave is had an X-rayed the on-the-spot holding time of technological work on hand method, influences production; The workplace tilt length is big, reaches 250-300m, and its penetration capacity is limited.
The utility model content
The utility model purpose provides a kind of overlength workplace radiowave perspective CT test macro, can't be applicable to the problem of long coal mine work area of length to solve radiowave perspective technology.
In order to achieve the above object, the technical scheme that the utility model adopted is:
A kind of overlength workplace radiowave perspective CT test macro; It is characterized in that: comprise radio wave penetration system with a transmitter and a receiver; Said transmitter has a plurality of launching site; Receiver has a plurality of acceptance points, and a plurality of launching site of said radio wave penetration system transmitter are set in qually spaced in tunnel of mine laneway workplace, and a plurality of acceptance points of radio wave penetration system receiver are set in qually spaced in another tunnel of mine laneway workplace.
Described a kind of overlength workplace radiowave perspective CT test macro; It is characterized in that: said radio wave penetration system has a transmitter, two receivers; Said transmitter has a plurality of launching site; Receiver has a plurality of acceptance points respectively; A plurality of launching site of said radio wave penetration system transmitter are set in qually spaced in tunnel of mine laneway workplace, and a plurality of acceptance points of two receivers of radio wave penetration system are set in qually spaced in different tunnels, another tunnel of mine laneway workplace section respectively and form two active sections, and separated by a distance between two active sections.
Described a kind of overlength workplace radiowave perspective CT test macro; It is characterized in that: comprise two radio wave penetration systems; Two radio wave penetration systems have a transmitter, a receiver respectively; Said transmitter has a plurality of launching site respectively; Receiver has a plurality of acceptance points respectively, and two radio wave penetration systems a plurality of launching site of transmitter separately are set in qually spaced in tunnel of mine laneway workplace, and two radio wave penetration systems a plurality of acceptance points of receiver separately are set in qually spaced in respectively in another tunnel of mine laneway workplace.
The advantage of the utility model is:
1, recording geometry is flexible: three kinds transmit and receive recording geometry and can adapt to the requirement of different operating noodles spare, improve on-site data gathering efficient greatly, increase the measured data amount.
2, on-the-spot detection method is easy, and it is high that the radiowave perspective CT software of establishment is handled automaticity to data, and result of detection is clear and intuitive, precision is high, can satisfy the technical requirement that mining is produced fully.
3, the data processing parameter is many: combine multiple series of images contrasts such as actual measurement field intensity curve, field strength distribution, absorption coefficient, further improve data analysis capabilities, improve surveying accuracy.Can find out the above extension situation of tomography in workplace of drop 1m that the fully-mechanized mining working tunnel has disclosed; Can find out that drop is greater than the extension situation of half thick potential fault of coal in workplace in the fully-mechanized mining working; Can find out that thickness of coal seam is less than the distribution developmental state of 1m " the thick thinning belt of coal " in the fully-mechanized mining working.
