摘　　要：在综合分析南洺河铁矿复杂水文地质情况、民采空区分布散乱及南洺河铁矿与万年矿之间的特殊空间位置关系等复杂开采条件的基础上,通过岩体稳定性特征分析和安全开采影响因素分析,对南洺河铁矿开采过程中其自身及下游万年矿矿井安全进行综合评价,并提出南洺河铁矿安全开采合理建议,为矿区安全高效开采方案的设计提供依据。Based on a comprehensive analysis of complex hydro-geological conditions in Nanminghe Iron Mine, the scattered distribution of the mined-out area and the special spatial relationship between Nanminghe Iron Mine and Wannian Mine, a comprehensive safety evaluation on Nanminghe Mine and the downstream Wannian Mine during mining process of Nanminghe Iron Mine is made through the stability characteristics analysis of rock and the factors affecting mining safety. Then, a reasonable advice for safety mining of Nanminghe Iron Mine is proposed, thus providing a basis for the design of a safe and efficient mining scheme.
