| 摘 要： | 野外岩、矿石物性测定表明,研究区内钨锡石英脉矿石磁化强度大于5000×10-3A.m-1,而正常围岩和热变质弱蚀变岩石为微磁性或弱磁性,这为在矿区进行高精度磁测提供了可靠的地球物理依据。本次工作在研究区内进行了地面高精度磁法测量,探测地下钨锡矿化岩体引起的磁异常,并结合地质和钻探资料,对地下矿体进行磁异常人机交互反演,取得了较好的效果。

| Abstract: | Physical property test of the rocks and ores in the field shows that the tungsten-tin ore has a strong magnetic properties,magnetization is more than 5000 × 10-3A·m-1,while the normal rock and hot metamorphic rock are micro or weak magnetic,which provides a reliable basis for geophysicist to carry out ground high-precision magnetic measurement survey in the mining area.The research work in the area is to detect the magnetic anomalies caused by the underground tungsten-tin mine using the ground high-precision magnetic measurement, and to conduct magnetic anomaly Human-Computer Interaction Inversion for underground ore body. Compared with the geological and drilling data, the obtained results are good. |
