Charcoal resource and the raising rate of extraction are imperative.Ground Penetrating Radar is to determine shallow-layer media interior substance point with high frequency radio magnetic wave
A kind of high-precision geophysical instrument of cloth rule is one for finding the top coal coal thickness regularity of distribution of the thickness less than 10m
The effective means of kind.
Utility model content
Goal of the invention：In order to overcome the deficiencies in the prior art, the utility model provides a kind of exploration top of improvement
The Ground Penetrating Radar device of coal coal thickness, for exploring the regularity of distribution of top coal coal thickness.
Technical solution：To achieve the above object, the technical solution adopted in the utility model is：
The Ground Penetrating Radar device of the exploration top coal coal thickness of a kind of improvement, including Ground Penetrating Radar, slide plate and supporting rod；The cunning
The fitting top coal surface movement of plate upper surface, upper surface middle part is plane, is bent downwardly along the both ends of moving direction；Ground Penetrating Radar
Babinet be fixed in the middle part of slide plate lower surface, supporting rod is identical for two structure sizes and symmetrically arranged tripod, tripod
A line and the babinet of Ground Penetrating Radar fix, another a line simultaneously extends downwardly out straight-bar for grasping.
When in use, the straight-bar extended downwardly by two tripods of staff's held by both hands is high for the Ground Penetrating Radar device
Lift entire Ground Penetrating Radar device so that slide plate is bonded the movement of top coal upper surface always, and Ground Penetrating Radar can across pitch scanning top coal
Coal-bearing region, by electromagnetic echoes signal be delivered to computing system carry out Interpretation of profile.As a result of skateboard so that the spy
Land mine device can be suitable for the detection of hollow top coal, and friction and obstruction when being contacted by reducing Ground Penetrating Radar with top coal carry
High working efficiency.As a result of the structure of tripod so that entire Ground Penetrating Radar device is more firm.As a result of both hands
The structure held so that staff can adjust contact posture of the Ground Penetrating Radar with top coal in time according to actual conditions, avoid visiting
Ground radar with top coal is discontiguous happens.
Preferably, the spacing of described two tripods is more than 50cm, using the spacing slightly larger than one shoulder breadth of ordinary person, side
Just staff more can easily keep steady entire Ground Penetrating Radar device.
Preferably, the Ground Penetrating Radar selects 200MHz centre frequency screened aerials, and the signal that Ground Penetrating Radar is sent out is worn
After crossing the babinet upper wall surface and slide plate of Ground Penetrating Radar, it is directly entered top coal；Since Ground Penetrating Radar is close to top coal, the electromagnetic wave of transmitting
It will not travel in air, reduce interference；Using transmitting profile method, investigation depth disclosure satisfy that top coal between 0~10cm
The investigative range demand of coal thickness.
Preferably, the babinet upper wall surface of the Ground Penetrating Radar directly uses the central area of slide plate；The design can be effective
Reduce Ground Penetrating Radar and the spacing on top coal surface, be further reduced interference；Similar design, be by sled design be Ground Penetrating Radar
Tank floor to both ends extension then last volume structure.
Preferably, the quantity of the slide plate is two, which is moved easily, reduces resistance.
Advantageous effect：The Ground Penetrating Radar device of the exploration top coal coal thickness of improvement provided by the utility model, relative to existing
Technology has following advantage：1st, coal thickness exploration is carried out to top coal using improved Ground Penetrating Radar, application method is simple；It utilizes
It is thick that electromagnetic echoes measure top coal coal, due to research object can visual inspection, there is no other architectonic information to interfere, thus this
Precision obtained by the sounding of method is higher, can accurately obtain the top coal coal thickness information along tunnel, and then draw a circle to approve with certain
Can second mining scale top coal region；2nd, present apparatus principle is simple, and production operation is easy, and input cost is low, can realize safe height
Effect production, improves coal mining rate and utilization rate, has certain economic value；3rd, the technology is equally applicable for iron ore or non-gold
Belong to the mines such as ore deposit and realize safety economy second mining.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is top coal coal road diagrammatic cross-section；
Figure includes：1- slide plates, 2- Ground Penetrating Radar, 3- supporting rods, 4, top coal overlying strata, 5, top coal, 6- coal roads.
Specific embodiment
The utility model is further described below in conjunction with the accompanying drawings.
Ground Penetrating Radar device for a kind of exploration top coal coal thickness of improvement as shown in Figure 1, including Ground Penetrating Radar 2,1 and of slide plate
