摘　　要：以放矿理论研究为基础 ,以优化采矿结构参数为切入点 ,在梅山铁矿首先提出了大间距采矿理论并建立数学模型 ,填补了国内外无底柱分段崩落采矿理论的空白。在此基础上采用实验室试验、计算机仿真、现场工业试验等手段进行验证。Based on the ore drawing theory study and with optimizing mining structural parameter as the cut-in point, wide-spaced mining theory was raised for the first time for Meishan Iron Mine and the mathematical model established, filling the domestic and foreign blank of pillarless sublevel mining theory. Based on this, laboratory test, compute simulation and on-site industrial test were made for verification.As a result, the main technical and economic indexes of the mine were raised in an all-round way.

关 键 词：无底柱分段崩落法 大间距放矿 结构参数 技术经济指标
