The application of magnetic anomaly inversion system: Taking Nickel Mine in Sunitezuoqi surveying for example

随着计算机技术的迅速发展,磁异常反演及解释研究的不断深化,越来越多的算法研究应用于磁异常反演.介绍磁异常反演系统及广义逆反演算法.其中着重介绍了广义逆反演算法,将地球物理问题转化为优化问题,为了解决该优化问题所提出的方程组,转化为求解该病态方程组,求出该方程组的最小二乘最小范数解.并且以苏尼特左旗镍矿探测为例,采用高精度磁法进行探测,并采用磁异常反演系统进行反演,得到模型形态,结合地质资料进行推断解释.

With the rapid development of computer technology research has been deepened, and more and more of the algorithms , magnetic anomaly inversion and interpretation of has been applied to magnetic anomaly inversion. Magnetic anomaly inversion system and generalized reverse inversion algorithm are introduced in the paper. Generalized reverse inversion algorithm is mainly discussed. Geophysical problems is converted into optimization problems. In order to solve the equations proposed by optimization problem, we transform them into equations for solving the ill ones. Then find the equations of the least-squares minimum norm solution. Taking nickel mine in Sunitezuoqi surveying for example, high precision magnetic method is used for detection, , then magnetic anomaly inversion system is used. We can get the modelform, and explain it with geological data.
