摘要
陷落柱与围岩物理性质的差异,导致电磁场、弹性波场、重力立场和放射性物质等地球物理性质发生变化。在分析陷落柱地球物理特征的基础上,总结了探测陷落柱的技术方法及其原理和应用现状,通过对联合物探方法组合方式的分析,为不同介质充填陷落柱探查方法的选择提供依据,减少单一物探多解性,提高了探测精度。
The differences of materical composition and characteristics between collapse columns and surrounding rock, and causes changes in the geophysical properties of electromagnetic fields, elastic wave fields, gravitational positions and radioactive materials. Based on the analysis of the geophysical characteristics of the collapse column, this paper summarized the technical methods, principles and application status of the detection of the collapse column. Through the analyzed of the combination of geophysical methods,it has provided basis for the exploration methods selection of different media filling collapse columns, reduced the single geophysical multiplicity and has improved the detection accuracy.
