Abstract
The invention discloses a single-hole ground system for geological exploration. The single-hole ground system comprises a master control box, wherein the master control box is connected to a computer through an optical fiber; the other optical fiber leaded from the master control box bypasses a winch and is connected to a receiving antenna and transmitting antennas; a drilling rig is arranged at the external part of the rock wall; a drill rod goes deep along a drill hole; a drill bit is arranged at the front end of the drill rod; the receiving antenna is mounted in the hole of a section of the drill rod by the drilling rig; the transmitting antennas are symmetrically arranged on the rock wall perpendicular to the drill hole; the receiving antenna is mounted in the section of the drill rod and fed into the hole by the drilling rig; the feeding process is stopped for each certain distance; the transmitting antennas on the rock stratum wall transmit electromagnetic waves; the receiving antenna in the drilling hole receives the electromagnetic waves; a group of data can be acquired, and then the amplitude and speed tomogram of the medium can be obtained through simulation software; the acquired signals and data can be more accurate and abundant; the single-hole ground system has the characteristic of high-resolution imaging.
Description
Technical field
The present invention relates to geological exploration technical field, particularly the system of a kind of ground single hole detection geology.
Background technology
Borehole radar is a kind of special pattern of geological radar, compare it with common geological radar and have several outstanding features, such as utilize certain region under boring closely, antenna relatively close to the geological anomalous body that will measure or target, thus can cause in the accurate measurement of darker scope to target.External existing maximum probe reaches the borehole geologic radar of 2000 meters, is mainly used in crack detection, detecting caves, ore prospecting, tectonic structure charting and subterranean water enquire etc.Domestic also relatively backward in this respect, there is no high efficiency shaped article.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the invention is to the system proposing a kind of ground single hole detection geology, the signal of collection and data can be made more accurate, abundant, there is the feature of high-resolution imaging.
To achieve these goals, the technical solution used in the present invention is:
The system of a kind of ground single hole detection geology, comprise Main Control Tank 3, Main Control Tank 3 is connected to computer 1 by optical fiber 2, winch 4 walked around by the optical fiber 2 that Main Control Tank 3 is drawn, and be connected to receiving antenna 6, emitting antenna 7, crag outside is provided with rig 5, drilling rod 8 along boring deeply, drilling rod 8 front end is provided with drill bit 9, and receiving antenna 6 loads in the hole of a joint drilling rod 8 by rig 5, and emitting antenna 7 is symmetricly set on the crag perpendicular to boring.
Described emitting antenna 7 adopts non-shielded half-wave doublet flagpole antenna, and centre frequency is set as 50 hertz, and sample frequency is set between 300 to 650 hertz.
Because the present invention adopts single hole geology detecting, can be suitable for carrying out deep detection, make collection signal and data more accurately with abundant, can realize high-resolution imaging, the scope of application is wide.
Accompanying drawing explanation
Accompanying drawing is structural principle schematic diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
See accompanying drawing, a system for ground single hole detection geology, comprise Main Control Tank 3, Main Control Tank 3 is connected to computer 1 by optical fiber 2, optical fiber 2 is used for transmitting the data of trigger pip and collection, winch 4 walked around by the optical fiber 2 that Main Control Tank 3 is drawn, and be connected to receiving antenna 6, emitting antenna 7, crag outside is provided with rig 5, drilling rod 8 along boring deeply, drilling rod 8 front end is provided with drill bit 9, and receiving antenna 6 loads in the hole of a joint drilling rod 8 by rig 5, and emitting antenna 7 is symmetricly set on the crag perpendicular to boring.Emitting antenna 7 adopts non-shielded half-wave doublet flagpole antenna, and centre frequency is set as 50 hertz, and sample frequency is set between 300 to 650 hertz.
Principle of work of the present invention is:
By rig 5, receiving antenna 6 being loaded a joint drilling rod 8 sends in hole, stop sending to every certain distance, by emitting antenna 7 emitting electromagnetic wave of rock stratum wall, receiving antenna 6 in boring receives electromagnetic wave, gather one group of data, amplitude and the topographic imaging by velocity figure of medium can be obtained by simulation softward.
