摘要
介绍了利用磁法探测侵入煤矿主采煤层岩浆岩边界的原理及工作方法 ,确立了煤层受岩浆岩侵入变质的变质煤具有较其围岩高的磁异常 ,并以此为理论依据圈定岩浆岩的边界。经生产验证该理论与客观实际相吻合。
This paper mainly introduces the principle and operating methods in detecting the magmatite boundary intruded into main coalbed.It proved that metamorphic coal caused by magmatite intrusion contains higher magnetic anomaly than its surrounding rock which was regarded as the theoretic basis for determining the magmatite boundary.Through practice,it is verified that the theory is corresponding to objective reality.
