Paper Title:
Optimization and Tests on the Independent Advance of Ore Breaking with High Sublevel and Large Drift Interval
  Abstract

According to the mining conditions and equipment level of Xingshan iron mine, optimization research on the stope structural parameters of sublevel caving was made, and finally adopted the structure parameters with 15m sublevel height and 20m drift interval. In order to find out the rational independent advance of ore breaking under 15m×20m structural parameters, theoretical arithmetic and industrial tests were carried out. The tests show that the rational independent advance of ore breaking drift interval should be 3.4m, and the optimized structural parameters of 15m×20m×3.4m has excellent effects on reducing mining cost and improving mining recovery rate.
