摘　　要：冀东变质岩区磁铁矿床发育,多为鞍山式磁铁矿床,区域内矿山林立,现阶段矿山铁矿开采已到浅部资源枯竭的瓶颈期,高精度磁法可以寻找变质岩区深部磁铁矿体,经过钻孔验证磁异常,寻找磁铁矿体,为矿山后期开采提供资源量,解决当下矿山面临的资源危机。本文重点论述冀东某矿山高精度磁法深部找矿成果,为冀东其他此类型矿山找矿提供启示和借鉴经验。Magnet deposits are developed in metamorphic rock area of eastern Hebei Province. Most of them are Anshan type magnetite. The area is abounded with mines. At present, each mine has reached the bottleneck stage of shallow resource exhaustion. High precision magnetic method can be used to search deep magnetic orebody in metamorphic rock area. Magnetic anomaly is verified by drilling and magnetite ore body is searched, provide resources for the later mining of the mine, solve the resource crisis facing the current mine. This paper focuses on the results of high precision magnetic prospecting in a mine in eastern Hebei Province, it provides enlightenment and reference experience for other such mines in eastern Hebei Province.
