首先对矿井瞬变电磁法的理论和磁感应探头的硬件结构进行了介绍。同时,利用磁感应探头和接收线圈,分别对同煤集团四台煤矿的414水仓和81025侧帮分别进行了超前探测验证试验。结果表明:采用磁感应探头代替传统的接收线圈不仅具有可行性,而且可以达到与传统接收线圈的相同的测试效果。由于磁探头结构具有体积小、质量轻及便携式等特点,在煤矿井下超前探测中具有广泛的潜在应用。
Firstly, the theory of mine transient electromagnetic method and the hardware structure of magnetic sensor are introduced. At the same time, using the magnetic sensor probe and the receiving coil, respectively, the coal group of 414 coal silos and 81025 side of the gang were carried out ahead of Prove the test. The results show that it is not only feasible to use the magnetic induction probe instead of the traditional receiving coil, but also to achieve the same testing effect as the traditional receiving coil. Due to its small size, light weight and portable characteristics, the magnetic probe has a wide range of potential applications in advanced detection in coal mines.
