针对煤矿区岩浆岩侵入体,分析了如磁化率、密度、顶面埋深、水平展布范围、垂直延伸长度等参数条件下岩浆岩侵入体引起的重力、磁力异常;介绍了现有重力勘探仪器和磁法勘探仪器的分辨能力;结合岩浆岩侵入体引起的物探异常,提出了重力勘探和磁法勘探工作布置的具体要求及其仪器的操作方法。研究显示,物探方法尤其是重力勘探、磁法勘探探测煤矿区岩浆岩侵入体能获得有意义的异常,可圈定岩浆岩侵入体的分布范围。

The paper analyses the size of gravity and magnetic anomaly caused by magmatic rock invasion under condition of certain parameters, such as magnetic susceptibility, density, the buried depth of the top, horizontal scope and vertical extension, and introduced the resolution ability of existing gravity exploration instruments and magnetic exploration instruments. Combining with the size of gravity and magnetic anomaly caused by magmatic invasion, the authors discussed some concrete requirements for the working layout of gravity and magnetic ex-ploration work and instrument operation methods in order to create the most favorable preconditions for acquir-ing geophysical anomaly caused by magmatic rock invasion, so as to locate magmatic intrusive mass in coal mining area.
