摘要

针对目前中国矿灾源探测范围小、精度低的问题,研制了一种新型可插拔组合低频天线,涉及12.5MHz、25 MHz和50MHz三个频率。与现有的许多天线相比,新设计的板型结构天线可以提高指向性,减少驻波干扰。进行了探雷实验,结果表明,新型天线能够有效探测深度大于30m、直径大于3m的地质灾源的位置和深度,最大探测深度可达80m,突破了目前探测深度30m的限制。

Development and application of a novel combined low-frequency antenna for ultra-deep advanced detection in mine
This paper presents the development of a new pluggable combined low-frequency antenna, involving three frequencies of 12.5MHz, 25 MHz, and 50MHz, aiming to solve the current problems of the small detection range and low precision in mine disaster sources detection in China. Compared with many existing antennas, the novel designed plate-type structure antenna can enhance the directivity and reduce the standing wave interference. Mine detection experiments were carried out and the results show that the novel antenna can effectively detect the location and depth of geological disaster sources with a depth greater than 30 m and a diameter greater than 3m, the maximum detection depth can be up to 80m, which breaks the current detection depth limitat of 30m.
