摘要： 为保证钟九铁矿的安全开采，根据钟九铁矿的水文地质工程地质条件以及矿山的采矿方法，通过理论分析和数值模拟相结合的方式，分析计算了钟九矿山顶板导水裂隙带高度、防水顶柱合理厚度及其留设位置，并结合矿山第四系含水层的水文地质特征和发育深度，综合得出钟九矿富水矿体开采覆岩扰动边界。

关键词: “三下”开采, 导水裂隙带高度, 防水矿柱厚度, 上部开采边界

Abstract: In order to ensure the safe mining of Zhongjiu Iron Mine,according to the hydrogeological engineering geological conditions and mining methods of Zhongjiu Iron Mine,the height of waterconducting fracture zones,the reasonable thickness of waterproof pillars and its location are analyzedand calculated by theoretical analysis and numerical simulation.Moreover,combining the hydrogeological characteristics and development depthof Quaternary aquifer in Zhongjiu Iron Mine ,the disturbance boundary of overburden in waterrich orebody mining in ZhongjiuIron Mine is calculated.

Key words: Under Three′ mining, Height of waterconducting fracture zone, Thickness of waterproof pillars, Top mining boundary
