CHINA MINE ENGINEERING

This article is based on the transient electromagnetic method technology to detect the location, shape, and water rich fractured areas of existing goaf areas. Combined with existing geological data, a comprehensive analysis is conducted on the scope and water accumulation conditions of goaf areas and karst water rich areas, providing scientific reference for the comprehensive investigation of hidden disaster causing factors. The research results indicate that the transient electromagnetic method technology hopes to provide new technical means and theoretical support for the geological characteristics and hazard assessment of phosphate mining goaf, and provide scientific basis for the safe operation of related engineering projects.
