Optimization Studies on Pillar Size of Fully Mechanized Caving Face

Abstract:

By theoretical calculations, numerical simulation and field monitoring methods to analyze the stress distribution and the extent of damage of coal pillar determine a reasonable size is about 10m, can improve the recovery rate of coal resources, and to ensure the roadway stability. 10m pillar coal resources compared with the previous 20m pillar recovery increased by about 5.5%, and created tremendous economic benefits of the mine.
