Abstract
Analysis on full-domain apparent resistivity characteristics of ground-tunnel transient electromagnetic method
Highlights
With the increase in coal mining depth, the hydrogeological conditions of mines are becoming more and more complicated, and coal mine water inrush disasters seriously threaten the safe production of coal mines (Wu 2014)
This paper further analyses the response characteristics of the full-domain apparent resistivity curves of receiving points changing with the stratum parameters at different depths and offsets according to the method features of electromagnetic wave emission in ground launching and electromagnetic wave receiving in the tunnel
By comparing the curves of the four geoelectric models, we can be that the full-domain apparent resistivity curves of all four geoelectric models can reflect the electric structure of corresponding stratum when the receiving point is located on the earth’s surface
Summary
With the increase in coal mining depth, the hydrogeological conditions of mines are becoming more and more complicated, and coal mine water inrush disasters seriously threaten the safe production of coal mines (Wu 2014). Cui Jiangwei calculated full-domain apparent resistivity based on the relationship between magnetic induction intensity and resistivity (Cui et al 2015). These studies have played an important promotional role in the accurate interpretation of transient electromagnetic data. Both the measurement points and emission loops of ground-tunnel TEM have offsets in both the vertical and horizontal direction. There is no published analysis of the apparent resistivity curve characteristics of the method, so it is necessary to study the resistivity characteristics of ground-tunnel TEM in different geoelectric models in order to gain a more intuitive and reliable interpretation method for the reconnaissance method
