摘要
应用高精度重磁勘探方法解决在推覆体下找煤问题。利用磁异常研究辉绿岩体的赋存状态，肯定了推覆体的存在；根据重力异常及数据处理结果研究推覆体下煤系地层的分布，指出太山—许台重力低带是测区内找煤最为有利的靶区。高精度重磁勘探是推覆体下寻找煤系地层前期勘探的有效手段之一。
The high resolution gravity and magnetic survey was used to solve the problems in coal exploration under nappe.The existent state of diabase was strudied with magnetic anomalies,and the existence of nappe was confirmed.The distribution of coal series strata under napper was studied according to the gravity anomalies and thier data processing results,and it was pointed out that the best potential target area for coal exploration was the Taihang Xutai gravity low zone.The high resolution gravity and magnetic survey is one of the effective means in early stage exploration to look for coal series strata under nappe.
