ABSTRACT

Recently, the aeromagnetic survey with Unmanned Aerial Vehicle (UAV) for mineral exploration has become ubiquitous. They can fly at a lower speed, lower altitude, need fewer crew members, and are cost-effective compared to traditional manned aeromagnetic. With the development of drones, magnetometers were also developed, which reduced the cost, weight, size, and energy consumption of these sensors. One of these sensors is the magneto-inductive magnetometer. This study investigates the integration of the UAV with a magneto-inductive sensor. We have performed an aeromagnetic survey along with six profiles and compared them with the terrestrial magnetic survey using a proton precision magnetometer. We show that the magneto-inductive sensor can sense Earth’s magnetic field’s change up to less than 60 nT. These results show the promising potential of using the UAV equipped with the magneto-inductive sensor to prospect the magnetic ore deposits.

摘要

最近，无人飞行器（UAV）进行的用于矿物勘探的航空磁测已经变得无处不在。与传统的载人航磁相比，它们可以以更低的速度，更低的高度飞行，需要的机组人员更少，并且具有成本效益。随着无人机的发展，还开发了磁力计，从而降低了这些传感器的成本，重量，尺寸和能耗。这些传感器之一是磁感应磁力计。这项研究调查了无人机与磁感应传感器的集成。我们已经进行了一次航空磁测量以及六个剖面，并使用质子精密磁力计将它们与地面磁测量进行了比较。我们表明，磁感应传感器可以感应到小于60 nT的地球磁场变化。
