摘要
可控源音频大地电磁测深法(CSAMT)是资源勘查的新技术,在地形起伏变化较大的山区及探测目标较深的隐伏煤矿区,该方法有一定的优越性。通过该方法在福建大田县东西坑、龙岩红林坪隐伏煤矿区应用实例,对其找煤应用效果进行分析和探讨,煤系地层低阻异常可清晰识别,CSAMT法物探解释成果与地质钻探成果基本相符,该方法可作为福建隐伏矿区找煤的一种主要物探手段。
The controlled source audio-frequency magnetotellurics (CSAMT) is a new technology for resources exploration.The Method has some advantages in mountainous areas of high topographic relief and concealed coal mine areas with exploration targets at depths.The results of coal exploration with CSAMT method are analyzed and discussed by examples.The low resistivity anomaly of coal-bearing strata can be clearly identified and the results of CSAMT geophysical interpretation are in agreement with those of geological drilling.Therefore,CSAMT can be used as a main geophysical method for coal exploration in Fujian concealed coal mine areas.
