It is provided with ram cell in described data acquisition unit.
The detection method of down-hole drilling structure, is characterized in that, comprise the steps of:
1), before going down into a mine, on ground, charged device 1 is connected by the second data wire 4d with detection pipe 5, is connected by electric wire 4c and main frame 3, full charge.
2) to after mine under, open detection pipe 5 and the power supply of main frame 3, carry out initializing (i.e. time synchronized) by the button of main frame 3 and operate so that display interface countdown shows；
3) unload and detect the second data wire 4b that pipe 5 is connected, loading onto the Ma241 radioactive source of 30 millicuries, and detection pipe 5 is sent at the bottom of hole；
4), after interface to be shown is adjusted, promote detection tube method by drilling rod and log well
5) after being measured, record sampling number and the degree of depth, detection pipe 5 is taken out from aperture, unloads radioactive source and put into carrying shield, covering tightly carrying shield lid；
6) unload detection pipe 5 second data wire 4b and detection pipe the 5, first data wire 4a and main frame 3 is connected, surveyed for detection pipe 5 data communication is got final product gug to main frame 3.
7) to behind ground, open main frame 3 power supply, then the depth measurement data communication of the log data that will come from detection pipe 5 communication in main frame 3 and depth finder 4 carry out log drawing to computer 2.
8) computer 2 has led to news and can turn off main frame 3 power supply, and so far, underground logging work is fully completed.
Preferably, step 4) in drilling rod promote detection tube method be: detection pipe 5 and drilling rod are coupled together and send at the bottom of hole, then it is displaced outwardly with connecting a stroke with one stroke of rig, in moving process, detection pipe 5 carries out log data acquisition, meanwhile, main frame 3 is by the degree of depth of depth finder 4 record well logging；In extracting drilling rod well logging, first keep deep control lamp bright, promote the speed≤10cm/S of detection pipe.

Detection pipe 5 operation principle
1. natural γ measures
Use nature γ measurement is the natural radioactivity intensity of rock and coal bed, uses sodium iodide (NaI) scintillation crystal and photomultiplier tube to make gamma detector, and the pulse that photomultiplier tube produces, control circuit data acquisition is also stored in ram cell.
2. select gamma-spectrometry
Selection gamma with the main distinction of general scattering Gamma logging is, gamma-spectrometry detector is selected all to have the beryllium window (Z=4) of low atomic number, and crystal the thinnest φ 30 Χ 2mm, purpose is intended to measure gamma ray and rock, the photoelectric effect of coal facies interaction, and 4 power that photoelectric effect is atomic number Z to material are directly proportional.Due to Z≤6 of the Main Ingredients and Appearance charcoal of coal, and the average effective atomic number Z ＞ 13 of rock, therefore, this method can divide coal seam and dirt band effectively.And using the AM241 of 30 millicuries as logging radiation-resource, its energy is low, little to human body radiation close rate, and easily shielding is portable.This road measuring circuit and GR circuit are just the same.
This instrument is to use time interval sampling, i.e. 1s samples once, and detects pipe 5 and be connected on drilling rod by one stroke of rig, be displaced outwardly a stroke.Moving process experienced by acceleration, two stages of speed stabilizing, and translational speed is not constant, so each two sampled point spacing is, and time and depth transfer to be carried out.If requiring that each journey time of rig operations is the most close, namely the sampling number M in a haul distance being close, if detection pipe translational speed V m1 function representation, it may be assumed that V=f (m1)
Thus can seek the sampling interval of each sampled point:
Δ H1=(mo/m) .f (m1-1). Δ t
In formula: the sampling number in one stroke when mo, m----finding speed and well logging
The Δ t----sampling time
Having obtained the sampling interval of each sampled point, application software just can insert out equidistant log data, becomes map for being for data processing further with compilation.
Embodiment of above is only in order to illustrate the technical solution of the utility model and unrestricted, although this utility model being described in detail with reference to embodiment of above, it will be understood by those within the art that, the technical solution of the utility model can be modified or equivalent the most should not depart from the spirit and scope of technical solutions of the utility model.
