Embodiment 1
Adopt gravity and transient electromagnetic method that bauxite has been measured。Survey petrophysical parameter such as table 1 in district。
District's petrophysical parameter table surveyed by table 1
Bauxite is typical air slaking appositional pattern metalliferous deposit, buried depth major part from tens meters to 300 meters within, bauxite Ore-hosting Rock Series be a set of shale, clastic rock build, in Ore-hosting Rock Series, symbiosis has semisoft clay, hard paste, iron mine and troilite。Bauxite is carefully controlled among the karst negative land form that deposition substrate (limestone of mid Ordovician) is formed (i.e. the recessed bucket of limestone), the fluctuating quantity in the limestone of mid Ordovician karst erosion face underlied determines karst negative land form and the development degree in depression, recessed bucket, and is thus controlled Ore-hosting Rock Series and the thickness of bauxite layer, grade and deposit scale and form etc.。As can be seen from Table 1: bauxite and upper and lower country rock have certain electrical property difference and certain density variation。Can utilize this difference realize to bauxite prediction location。But owing to the physical property characteristic of bauxite is not obvious especially, the directly reflection of ore body is very unobvious, adopt the means that gravimetric prospecting combines with electromagnetic survey, it is possible to be greatly increased forecasting reliability。
1: high-precision gravity and magnetic method
First, carrying out gravimetric prospecting in Dai Gu district, in exploration result such as Fig. 3, Fig. 3, abscissa represents survey line measuring point number, and vertical coordinate represents gravity Bouguer anomaly value。The macroscopic view height change of gravity Bouguer anomaly curve in Fig. 3, what reflect interface, limestone top buries depth variation characteristic。Namely curve is convex shows that interface, limestone top upwards rises and falls, and curve rises and falls downwards to interface, recessed expression limestone top。At curve recessed bucket place, the low exception of local gravity often occurs, be that bauxite composes the favored site deposited。In Fig. 3, No. 150 measuring point to No. 450 measuring points are that scope is deposited in the tax of bauxite horizontal direction。
Transient electromagnetic method measurement is carried out in Dai Gu district。First placing earth-free loop line on ground, and send step current at earth-free loop line, earth-free loop line produces excitation electromagnetic field, and underground medium is sensed and produces vortex current；Receiving transducer is placed on the center of loop line, measures the inducted secondary field that underground medium produces。Situation of change according to inducted secondary field speculates that characteristic is deposited in the tax of detection objective body。
This detection adopts the multi-functional electrical method work station of GDP-32II that Zonge company of the U.S. develops。Emission system adopts NT-20 type transmitter, receives device and adopts TEM/3 antenna (probe)。Operating frequency is through scene test 16Hz, and transmitted waveform dutycycle is 50%, and operating current is 4A。GDP-32II instrument has arithmetic intensive sampling function at equal intervals, the electromagnetic response value in measuring point Observable hundreds of even thousands of moment, therefore the observation of more conventional method can obtain abundant ground electrical information。
Equipment adopts 100 meters × 200 meters large wire frames determine source apparatus, observation station from 20 meters, reception antenna launching in wire frame in 1/2nd scopes of centre, pointwise mobile observation。Groundwork arranges parameter: operating frequency 16Hz, waveform duty cycle 50%, and primary field decay time delay 120 microsecond, operating current is stable at 4.0A。Employing multiple stacking is observed, stacking fold 256, and when running into humane interference, stacking fold increases to 512 or 1024 times, and all measuring points have all carried out repeated measures, it is ensured that initial data observation quality is reliable。
Calculation formula of apparent resistivity according to Genter loop determines the apparent resistivity that described section sets up an office:
The calculation formula of apparent resistivity of described Genter loop isWherein, M is that magnetic moment is launched in source, is sized to the product of emission current and transmitting loop area；Q represents the capture area of observation position probe, and V (t) is the secondary induction voltage value measured, and t is observation time, μ0Pcrmeability for free space。
Investigation depth is calculated according to below equation:
With measuring point distance for abscissa, with the elevation of computed investigation depth conversion for vertical coordinate, computed apparent resistivity value is drawn as isogram (Fig. 4)。Fig. 4 clearly reflects the ground electricity structure of detected section, the reflection at limestone interface is relatively sharp, objective, the vertical degree of depth more than 160 meters reflects electrically uniform in the sand layers of stratiform spread, rammell, the recessed feature of contour that apparent resistivity value is 26 ohm of 〃 rice is obvious, substantially reflecting the fluctuating situation of substrate limestone of mid Ordovician, in Fig. 4, reflection depression, recessed pan position are Bauxite Mineralization beneficial zone。In conjunction with geologic information, electrical for Fig. 4 Interpretation On The Results is become geology result (Fig. 5)。In Fig. 5, red trap is bauxite position。The thickness of bauxite is 9 meters。The boring of No. 350 point positions confirms this interpretation results。
Although disclosed embodiment is as above, but its content is only to facilitate the embodiment understanding technical scheme and adopt, is not intended to limit the present invention。Technical staff in any the technical field of the invention; under the premise without departing from disclosed core technology scheme; any amendment and change can be made in the form implemented and details; but protection defined of the present invention, still must be as the criterion with the scope that appending claims limits。
