摘要
随着物探找矿的推进,找矿的难度越来越大,如何从复杂的叠加的弱信息中将我们需要的有用信息提取出来,是一件急待解决的迫切任务。这里在模拟、分析、总结了重力高阶导数在分离叠加异常的基础上,并应用到了实际资料的处理当中,利用重力高阶导数不同半径的交点比较准确地确定出了矿体的边界位置,同时与钻孔验证的结果基本一致,取得了良好的应用效果。
With the advancement of geophysical prospecting,it becomes more and more difficult.How to extract in the complex superposition of weak information from us useful information is an urgent task to solve.In this paper,simulation,a-nalysis,summarized the higher derivative gravity separation have been applied to the actual data processing on the basis of ab-normal superimposed .The use of higher derivative gravity intersection of different radius more accurately determine the loca-tion of the boundaries of the ore body.Meanwhile the result is consistent with the drilling validation achieved good effect.
