Abstract
The hidden geological disaster sources lead to frequent safety accident in mine, and the geological radar technology is widely used in the detection of geological structure and hidden disaster sources. This paper designs a geological radar antenna and shielding device for full space of mine roadway, aiming to improve the accurate identification ability for small target. The main frequency of the antenna is 200MHz. The simulation and mine test results show that the antenna has a best performance with the antenna flare angle at 80° and the shield height at 175mm in the full space environment. Compared with many existing antennas with low resolution, the new antenna system can effectively improve the detailed detection ability of the hidden geological disaster source in the shallow mine, which is of great significance for safe mining.
