Description

Technical Field

[0001] The present invention relates to the technical field of coal mine surveying, and more particularly to an auxiliary device for horizontal borehole radar inspection. Background Art

[0002] As a key tool in the field of geophysical exploration, borehole radar is widely used in the detailed exploration of coal mine geology, including the detection of coal seam roof and floor, geological anomalies, goaf and changes in coal seam thickness. In coal mine applications, borehole radar can achieve good detection effects. In order to detect the situation inside the borehole, the borehole radar needs to be placed in the borehole to detect the geological body and perform imaging. When drilling horizontal holes with large apertures, auxiliary devices for horizontal borehole radar are needed to maintain the stability of the borehole radar during detection.

[0003] In the Chinese invention patent with publication number CN110259432A, a drilling rig-pushed mining borehole radar precision detection device and method is mentioned, including a drilling rig, a drill rod, a non-metallic drill rod, a borehole radar, a non-metallic drill rod, a drill bit, a hole depth recorder and an explosion-proof mobile phone; the hole depth recorder is installed on the drilling rig to record the depth of the borehole radar in the borehole, and the explosion-proof mobile phone communicates with the hole depth recorder and the borehole radar to synchronize the time, issue parameter commands and transmit data for the hole depth recorder and the borehole radar; the borehole radar includes a control center module, a data storage module, a WIFI communication module, a battery, a trajectory measurement module, a transmitting antenna, a receiving antenna, a signal transmitter, a signal receiver, etc. The present invention can detect all boreholes in coal mines, with a measurable borehole depth greater than 500m. It can also measure the interface positions of geological anomalies, water-bearing anomalies, and coal seam roof and floor plates within a range of 1m to 10m around the borehole, with a resolution of 0.15m to 0.3m, providing precise guidance for intelligent mining in coal mines.

[0004] Although the above technical solution has effectively solved the problem of inconvenient information transmission during borehole radar detection, in actual operation, due to incomplete cleaning inside the borehole, drill cuttings and rock fragments are left behind, resulting in obstacles in the borehole. In addition, the geological layer of the borehole contains groundwater, which makes it easy for water and mud and other substances to accumulate in the hole after drilling. These problems will cause the borehole radar to have difficulty walking during the inspection process, reduce work efficiency, and the detection results are not accurate enough.
