Reconstruction of Underground Coal Seam Surface Based on B-Spline Surface Interpolation

摘要

Coal mine safety attracts the extraordinary attention of Chinese government in recent years, if we can't recognize the coal seams' distributing pattern in the coal mine production, lose goal and direction in the whole mining process, it will cause catastrophic accident. In order to provide convenience for mining scheme making and the security of mining area protecting, this paper proposes a method which combines the B-spline surface interpolation with Simulated Annealing (SA) to reconstruct the surface of the coal seam to get a fourth order surface equation and a minimized Sum of Squares for Error (SSE) fitting surface. Using the SA can get a fitting surface with minimum total error. The combination of interpolation and fitting methods makes the suggested method faster and practicable for use.
