摘　　要：地面高精度磁法剖面测量是矿产勘查工作中常用的一种地球物理勘查方法,它可以通过在地表覆盖层上的测量,大致了解地下磁性体的地下产状及赋存状态,也可以了解磁性体的大致规模及顶部埋深.由于受地形地貌等客观自然条件的限制,许多地方在进行地面高精度磁法剖面测量时,有许多剖面上的测点无法进行正常测量.作者根据磁性体异常的等值线特性,利用一种等值投影的方法,间接获取剖面上测点的磁异常值.从而巧妙的解决了地面高精度磁法剖面测量中,测线上点位缺失的问题.High precision Magnetic survey is a widely used geophysical exploring method for Multi metal mineral ore exploration.It can be used to find out the occurrence state by surveying on the overlap ground.And it can be used to estimate the scale and depth of magnetic body approximately.Because of the topography and other natural conditions,in many parts of the high-precision ground magnetic profile measurement,are unable to conduct normal measure on many profiles.According to the contour characteristics of magnetic anomaly,the method of equivalence projection,indirect access profile measuring point of the magnetic anomaly.In order to solve the highprecision ground magnetic profile measurement,measuring line point deletion problem.
