Floor mining damage analysis method and device, medium and equipment

Abstract

The invention relates to a floor mining damage analysis method and device, a medium and equipment. The method comprises the following steps: acquiring micro-seismic data of a coal face; an initial damage area is determined according to the micro-seismic data, and the initial damage area comprises areas where damage of different damage degrees is generated in the coal seam mining process according to the coal face; determining a transient electromagnetic detection area according to the initial damage area; performing transient electromagnetic detection on the transient electromagnetic detection area to determine a transient electromagnetic detection result; and determining a target damage area according to the transient electromagnetic detection result and the initial damage area. The analysis accuracy of the damage condition of the coal face bottom plate can be improved.
