摘要
Abstract
Salt mine is usually exploited by water-dissolving method that is prone to form dissolved cavity after years of exploitation, causing land subsidence.Therefore, it is needed to use effective geophysical prospecting methods to explore the distribution of underground dissolved cavity in salt mined area, which could provide valuable basic information to taking preventive measures for salt mines.By using transient electromagnetic method that is sensitive to the low resistance anomaly, and adopting several technical measures including increasing the emission current, multiplying observation times and avoiding the surface electromagnetic interference, the acquisition data quality is ensured.In addition, the underground cavity distribution is located through data processing and interpretation by advanced data inversion software.The results of this survey have good practical effects, which can provide reference to solving the similar geological problems in the future.关键词
