应用核地球物理方法勘探研究张浦盐矿区断裂系统

Using Nuclear Geophysical Method to Explore Fracture System in Zhangpu Salt Mining Area

本文介绍应用氡管法和α卡法探测张浦盐矿区的隐伏断裂构造。结果表明，该盐矿区存在有东西向及北东向两组断裂。根据观测结果推测出该区断裂系统。后者与该区钻孔资料遇到的断裂构造相吻合，为制订该盐矿区开采、布井设计的总体规划提供了宝贵的资料和可靠的依据。本试验结果证明氡法能够探明４００ｍ甚至更深部的断裂构造。

Radon pipe and alpha detection,emanation surveys to detect hidden fracture systems has revealed that there exist two fractures with directions of east-west and northeast in Zhangpu salt mining area. So,the fracture systems have been inferred based on the observation,the research results,similar to the fault structures described by the borehole data,offers important data and reliable basis for the exploration,design and planning of the mining area. The test indicate that the radon pipe method can be used to prove fault structures at 400m the depth or more.
