铁矿采场充填体合理强度研究

Study on Reasonable Strength of Stope Filling Body in Iron Mine

本文结合国内外对充填体强度设计经验,采用了有限元数值模拟、理论公式计算和经验类比三种方法,根据矿房不同高度与宽度,确定了马坑铁矿一步骤和第二步骤采场充填体所需要的强度,为矿山的安全、高效、低成本开采提供了理论依据。

Based on the strength design experience of filling body at home and abroad,the strength required by stope filling body in the first and second steps of Makeng Iron Mine is determined by three methods of finite element numerical simulation,theoretical formula calculation and empirical analogy according to different heights and widths of the ore house,which provides a theoretical basis for safe,efficient and low-cost mining of the mine.
