摘　　要：在强磁干扰的矿区，采用高精度磁测技术圈定煤系火成岩侵入体是一项直接为煤炭生产服务的工作。本文介绍煤矿矿区利用高精度磁测技术探测火成岩侵入体的有关技术问题，并以大屯矿区为例说明高精度磁测技术在强干扰矿区所取得的地质效果。To outline intrusive igneous rock is important for coal mining. High-precision magnetic survey is an essential work to solve this problem. Mostly,the cultural magneticnoise in coal mining area is very high. It is necessary to develop field and data- processingtechniques for overcoming magnetic noise and extracting useful information from fielddata. Many relative methods and techniques have been discussed in this paper.The effect ofhigh- precision magnetic surveys is shown by a case.
