Bibliometric Analysis of the Application of Electrical Exploration in Goaf
To understand the current research status of electrical prospecting methods applied in goaf areas in China,a total of 767 relevant articles published in recent years on the China National Knowledge Infrastructure(CNKI)were reviewed.A bibliometric analysis of the number of articles,authors,and keywords was conducted using CiteSpace V.6.3.R1 software,and the following conclusions were drawn:①The application of electrical prospecting in goaf areas has gone through stages of slow development,rapid growth,and stable fluctuations.② There is relatively little collaboration among authors and institutions,with most studies conducted independently.③Comprehensive geophysical prospecting methods are commonly used to detect goaf areas to improve detection speed and accuracy.Common electrical prospecting methods for detecting goaf areas include resistivity methods and transient electromagnetic methods.④Computer numerical simulation represents a future development direction for this field.
