Abstract
A method for detecting a structural abnormal area of a coal and rock mass is provided. The method includes acquiring a target velocity inversion map of the coal and rock mass in a target detection cycle, in which the target velocity inversion map is configured to indicate a target velocity of seismic wave propagation in each of grid cells in a target detection area, acquiring a first velocity of seismic wave propagation in any one of the grid cells in at least one detection cycle preceding the target detection cycle, determining, according to each of the first velocities and the target velocities, structural abnormal cells from each of the grid cells, and determining, according to the structural abnormal cells, a range of the structural abnormal area of the coal and rock mass in the target detection cycle in the target velocity inversion map.
