Paper Title:
Optimization and Application of High Production and High Efficiency Mining Parameters of Fully Mechanized Caving Face
  Abstract

The size of the fully mechanized caving face is optimized by theoretical analysis and the dip length of the face is determined as 260m. With the method of numerical simulation, the reasonable cutting height of the face is determined as 3.5m and the caving method is determined as one round caving in order. The physical simulation is used to analyze the caving effects under different drawing intervals and the reasonable drawing interval is determined as 0.8m. The coal recovery is improved by 3.43% after the parameters are applied in field and the goal of high production and high efficiency of the mine has been achieved.
