放矿仿真SLS系统及应用

The SLS System of Caving Mining Simulation and Its Application

无底柱分段崩落法分段高度、进路间距和崩矿步距等结构参数对矿石回收指标影响很大。概述了SLS系统的特点和功能以及数学模型,并利用SLS系统对梅山铁矿(该矿采用无底柱分段崩落法)进行多方案放矿仿真研究,结果与物理实验一致。仿真结果表明,在分段高度15 m和进路间距20 m参数下,步距取4 m为优。

The structural parameters of pillarless sublevel caving have big Influence with ore recovering, the parameters indudes sublevel height, sublevel drive interval, drawing-ore step and so on. The paper introduces features and functions of SIS system, and uses it to research on many indexes ore-drawing simulation of MeiShan iron mine （this iron mine uses the mothed of pillarless sublevel caving）, the simulation＇ result is in conformity with the physical experiment, the results show that best of the step value is 4 meter when sublevel height value is 15 meter and sublevel drive interval value is 20 meter.
