综合物探方法在冀东锰矿的应用效果

The effect of the application of comprehensive physical exploration method in Jidong manganese mine

锰矿广泛应用于冶金、电子、化工、建材等领域,和国家经济建设密不可分,近年来锰矿作为国家战略资源矿种越来越受到国家重视。本文以河北唐山某锰矿勘查为例,在第四系覆盖位置,采用地面高精度磁法、电法激电中梯工作,以“低磁—高极化”圈定出异常,指导锰矿工程施工。同时,为冀东乃至河北海相沉积型锰矿提供了有效的物探方法。

Manganese ore is widely used in fields such as metallurgy,electronics,chemical engineering,building materials,and is closely related to national economic construction.In recent years,manganese ore,as a national strategic resource,has been increasingly valued by the country.This article takes the exploration of a manganese mine in Tangshan,Hebei Province as an example.At the location covered by the Quaternary system,high-precision magnetic and electric medium gradient method were used to excite the middle ladder,delineating anomalies using “low magnetic high polarization” to guide the construction of manganese mine engineering.At the same time,it provides an effective geophysical exploration method for marine sedimentary manganese deposits in eas-tern Hebei and even Hebei.
