Analysis of influencing factors and its coupling degree of resistivity of rocks

Abstract

Abstract Over the years, it has been carried out on the method of resistivity exploration mainly from the macro level, and it has made a greater contribution to the search for minerals. However, it is found that the data interpretation effect obtained from the macro level for ore deposit exploration has a large error. Therefore, the research on the method of resistivity exploration of rock and ore from the micro level has become a new research difficulty and hot spot. Based on the team’s previous experimental analysis and research, this paper takes the Chazangcuo Cu-Pb-Zn deposit as the research object, carries out the study of the resistivity of rocks from the microscopic level, and focuses on the study of water content, temperature, pressure, porosity and other influencing factors of the Chazangcou deposit, with the help of field geological survey, testing, and analysis. The coupling process of the influencing factors is analyzed based on the experimental results and the grey correlation idea, and the calculation of the coupling degree is proposed to indicate the degree of coupling. According to the results of the test and calculation, the coupling degree of resistivity of rocks is water content>porosity>temperature>pressure.
