Study on Simulation and Optimization for the Relationship Between End Wall Dip Angle and Breaking Interval for Sublevel Caving

Abstract

Abstract: In order to enlarge the structural parameters in an iron mine，the computer simulation system of self-developed pillarless caving method ore-drawing is utilized to gain the relationship between different end wall dip angle and different breaking interval Meanwhile, the optimal breaking interval is determined by the lab ore drawing tests.The research results could provide the technical support for an iron mine to achieve the goal of safety，efficiency and inexpensive mining under structural parameters of 18 m×20 m.

Key words: Face-end ore-drawing, Computer simulation, SLS, Structural parameters
