Optimization of Coal Mining Scheme in Lugou Coal Mine and Mining Effects on Village

In order to reduce mining damage, protect the safety of surface buildings and improve coal recovery rate, three mining schemes were proposed on the basis of geological mining conditions in Lugou 32051 working face. By using probability integral method and FLAC^3D numerical simulation, the surface movement and deformation values of different schemes were predicted, and the damage situations of five groups of private houses in Zhaozhai village were compared and analyzed. The best mining scheme was determined and field practice was carried out. The results showed that houses were less affected by mining damage and safer. The recovery rate of coal resources had been raised when scheme 3 was used.
