In order to develop coal resources scientifically and reasonably, Luning coal industry adopted three-dimensional seismic exploration in the second and third mining areas (lower part), and analyzed the occurrence conditions and development characteristics of the main coal seams in the second and third mining areas (lower part). The exploration results showed that the modern 3D seismic exploration technology can obtain high-quality seismic data in the complex surface area. Through reasonable data processing and combining with the existing geological data, the 3D seismic exploration results can provide strong guidance for the mine development decision-making, roadway layout and development.
