有底柱阶段崩落法底部结构及放矿制度优化

OPTIMIZATION OF BOTTOM STRUCTURE AND DRAWING REGIME IN BLOCK CAVING WITH BOTTOM PILLARS

本文通过有底柱阶段崩落法采场各参数的分析、比较及计算机模拟 ,以经济技术指标最优为原则 ,论述了其优选方法和过程 ,并将这种方法应用于实际 。

By analysing and comparing the stope parameters of block caving with bottom pillars and by computer simulation,taking aim at optimal economic technic indexes,this paper studies their optimization methodes and processes.The methods have been applied into practice and good results have been achieved.
