Visual Expression

High density resistivity method have integrated resistivity method and induced polarization method. It is widely used in exploring metallic deposits, especially metallic sulfide deposits. The aim of this article is to study three-dimensional inversion and visual expression of two-dimensional profile survey data in high density resistivity. After testing computing capability and application effect of three-dimensional inversion, the results show that the change rules of resistivity can be seen more clearly. And the visual expression after three-dimensional inversion is able to help us observe the distribution characteristics of resistivity with various perspectives. These results are helpful for us to deduce distribution characteristics and special locations of geological structures. They are also helpful to do some effective geological explaining works for spatial distributions and changing rules of ore deposits.

Electric Profiling

High-density resistivity method is a new, efficient electrical prospecting method, which can complete a two-dimensional (vertical and horizontal) prospecting process, possesses certain imaging functions for the geo-electric structure, and integrates electric profiling method with electric sounding method together. In this paper, the basic principle, data processing, and result explanation and inference of high-density resistivity method are introduced by taking the application of high-density resistivity method to the prospecting project in the slope of Gongchangling Open Pit, Liaoyang. The result of the prospecting result map analysis showed that the prospecting result was basically in line with the actual situation and proved the great significance of high-density resistivity method to the evaluation on the slope stability of Gongchangling open pit.

Great Harm

The karst cavities can cause great harm to the construction or running of expressway. During the construction of expressway, the detection of these unfavorable geological objects is usually by use of high density resistivity method, and the physical background of the method is the combination of high resistivity of bedrock and low resistivity of karst cavities. In the study area, the Kaihua segment of Hangzhou-Xinanjiang-Jingdezhen Expressway, the widely distributed rich carbonaceous bedrock shows low resistivity, and the conventional interpretation idea of high density resistivity method is not applicable. The research results of this paper suggest that the U shape of relative high resistivity can be an indicative for detection of unfavorable geological objects such as karst cavities. 6 out of 11 boreholes drilled for purpose of calibration revealed karst cavities, and the karst ratio is from 1.2% to 10.3%, indicating the new interpretation method is feasible and reliable.
