Description of drawings
Fig. 1 is the structural representation of the transient electromagnetic exploration device of a kind of embodiment of the utility model;
Fig. 2 is the structural representation of the transient electromagnetic exploration device of the another kind of embodiment of the utility model.
Embodiment
Transient electromagnetic method is to utilize earth-free loop line or ground connection line source to underground emission pulsatile once magnetic field, at pulsatile once magnetic field tempus intercalare, utilize the secondary inductive loop field that causes in coil or the ground-electrode observation underground medium, thus a kind of method of probing medium resistivity.
Transient electromagnetic exploration device in a kind of embodiment of the utility model comprises: power supply, be used for to underground emitting radio frequency signal emission part, be used for receiving the acceptance division of the reflection wave that emission part transmits.Wherein, the power supply (not shown) is connected to power acceptance division and emission part wireless connections to emission part with emission part.
Preferably, described power supply is EP500 type power supply.
On ground or the aerial emission part (for example transmitting coil) that passes to certain waveform electric current that arranges, thereby produce an electromagnetic field at its surrounding space, can produce induction electromotive force in the underground conduction rock ore body.Acceptance division (for example receiving coil) receives induction electromotive force.This electromotive force has comprised the underground medium electrical property feature, can draw the structure of subterranean strata by suitable interpretation algorithms (one-dimensional inversion, apparent resistivity etc.).
As shown in Figure 1, in one embodiment, adopt and to decide greatly that wire-retracting device is as the transient electromagnetic exploration device in the source in, emission part is to launch wire frame, i.e. the first rectangular wire frame Tx; Acceptance division is for receiving wire frame, i.e. the second rectangular wire frame Rx, and the length of side of the first rectangular wire frame is greater than the length of side of the second rectangular wire frame.Preferably, as shown in the figure, the length of side L of the first rectangular wire frame is three times of length of side L/3 of the second rectangular wire frame.
As shown in Figure 2, in another embodiment, can also adopt the dipole device as the transient electromagnetic exploration device.In this mode, preferably, emission part is rectangular wire frame Tx; Acceptance division is circular receiving coil Rx.
Carry out can also carrying out following operation in the process of resistivity detection at application the utility model:
1. apparatus suitability test
For example: carry out repeated measures in same point 2 times with same parameter, relatively the consistance of the data obtained.
2. send the test of the wire frame length of side and transmission frequency
Sending the wire frame length of side can directly affect prospecting depth, and under same frequency, the wire frame length of side is larger, and investigation depth is darker.So according to zone of interest buried depth and regionally detecting experience, this test sends the wire frame length of side and selects 200m * 200m, 240m * 240m, three sizes of 300m * 300m to test, the effective transmission wire frame length of side of final selection is formally constructed, to satisfy the requirement of this prospecting.
Because the EP500 type power supply of the power acquisition in the present embodiment, when power transit line was 50Hz, transmission frequency was 2.5,6.25, three class of 25Hz are optional, and the lower investigation depth of frequency is larger, can carry out multiple combination before surveying and test, carry out data acquisition to determine optimal parameter.
Although the utility model is described by above-mentioned preferred implementation, but it realizes only being not limited to above-mentioned embodiment, should be realized that in the situation that does not break away from the utility model spirit and scope those skilled in the art can make different variations and modification to the utility model.
