基于不同探杆高度的钢板模型磁法探测

Magnetic Detection of Steel Plate Model Based on Different Probe Height

磁法勘探是寻找铁矿的一种重要方法,目前野外常规磁法勘探时探杆为4根,高度达2m,携带很不方便。笔者通过不同时间、不同探杆高度对钢板磁法勘探的试验结果表明,不同时间、不同探杆高度均可以找到钢板的具体位置,其中2根探杆的钢板异常值最大,探测效果最佳,打破了常规磁法勘探4根探杆的模式,为野外磁法勘探提供了新的思路。

Magnetic prospecting is an important method to search for iron ore.At present,conventional magnetic prospecting in the field has four poles with a height of 2 m,which is very inconvenient to carry.Through the test results of magnetic prospecting for steel plate in different time and different height of exploration rod,the author shows that the specific position of steel plate can be found in different time and different height of exploration rod.Among them,the steel plate of two exploration rods has the largest abnormal value and the best detection effect,it breaks the mode of four poles in conventional magnetic prospecting,and provides a new idea for field magnetic prospecting.
