摘要:
焦家金矿田作为典型破碎蚀变岩型(焦家式)金矿床,探明金资源储量已突破千吨,是目前胶东金矿地球物理探测的焦点区域。针对研究区内矿山开采所带来的工业电磁干扰对CSAMT、MT和SIP等传统电磁勘探方法影响较大的问题,开展了在强工业电磁干扰环境下地球物理方法对胶西北矿集区主要控矿断裂深部响应特征及适用性研究,在焦家金矿田寺庄典型矿段开展微动探测试验工作,通过多重圆台阵变换和不同半径台阵变换的微动探测试验研究,进行空间自相关法分析。结果表明:微动探测视横波速度场特征与主控矿断裂具有耦合关系,通过试验参数优选,可基本实现3 000 m深度区间内焦家断裂带的垂向识别,为今后微动探测方法在胶西北矿集区开展相关勘查工作提供依据。
