What is it about?
Lu et al. present the results of a case study on the use of 3D-3C seismic data for coal seam prediction in the Guqiao coalmine in China. The structure, fracture development, thickness, surrounding rock lithology, roof stability, and mining safety of coal seam 11-2 were determined by joint PP- and PS-wave inversion and interpretation.

Why is it important?
With the increasing mining depth of coal mines, geologic hazards have become the main source of accidents. For this reason, coal seam prediction requires more assessment parameters, such as the degree of anisotropy, VP∕VS value, and elastic modulus. These parameters are difficult to determine using only the PP-wave.
Perspectives
Our joint PP- and PS-wave inversion and interpretation provides more information for coal seam prediction, creating a new application for coal seismic survey.
