摘　　要：以某铁矿为研究背景,将实验室放矿模拟与数值模拟相结合,对放矿参数进行相关研究,最终确定合理的崩矿步距、进路间距、分段高度等参数。该研究方法给矿山生产实践提供了新的思路,同时,为类似矿山放矿研究提供了理论依据和指导。Take an iron mine as the research background,combine the laboratory of discharge simulation and numerical simulation,make research on ore drawing parameters,it is determined that a reasonable caving step distance,route spacing,height and other parameters segmentation. The research methods provide new ideas to mine production practices,it also provides a theoretical basis and guidance to similar mines.
