近年来,随着国民经济的快速发展,工业生产对矿产资源的需求也不断的增加。与此同时,随着近些年来金属矿的勘探和开发的迅猛发展,第一深度空间(小于500米)的矿产资源绝大部分已经探明,金属矿勘探进入了第二深度空间(500-2000米)的探测与开采。对于存在于第二深度空间的矿体由于埋藏较深、受热液侵入及构造破碎的影响,矿体与周围之间的电性和磁性参数引起的地球物理异常变得相对更弱,这使得反演多解性问题变得更加突出,同时随着深度的增加勘探的分辨率急剧下降。
In recent years, with the rapid development of the national economy, the demand for mineral resources in industrial production has also been constantly increasing. At the same time, with the rapid development of metal exploration and development in recent years, the vast majority of the mineral resources in the first deep space (less than 500 meters) have been proven and metal exploration has entered the second deep space (500- 2000 meters) exploration and exploitation. The geophysical anomalies caused by the electrical and magnetic parameters between the ore body and its surroundings become relatively weaker due to the deeper burial, invasion of hydrothermal fluids and the structural crushing of the ore body existing in the second depth space, which makes the The problem of inversion of multiplicity becomes more prominent, and the resolution of exploration decreases sharply with increasing depth.
