摘　　要：多层排列矿床阶段高度是矿床安全开采的关键因素之一。通过分析多层矿床不同开采方式相邻矿层的扰动影响关系,建立安全开采阶段高度与矿层间距、岩石移动角和矿层倾角等赋存因素之间的解析关系式,在此基础上分析研究各因素对安全开采阶段高度的影响规律。研究表明,安全开采阶段高度H随矿层间距a、下盘岩石移动角γ1的增大而增大,随下盘矿层倾角α2的增大而减小;上层矿安全开采阶段高度h随矿层间距a、上盘矿层倾角α1、上盘岩石移动角β2的增大而增大。各因素对H、h的影响依次为:α2>a>γ1;a>α1(β2),这一研究可为选取多层矿床安全开采阶段高度提供参考依据。Stage height on multi-layer deposit is one of the key factors for safety mining.By analyzing disturbance influences between neighboring layers under different mining methods,it was found that safety stage height related to ore layer space,the rock mass movement angle and the ore layer inclination,further more the analytic function was established.The study showed that safety stage height（H）increased with the increase of ore layer space（a）and footwall movement angle（γ1）,however,decreased with the increase of bed ore layer angle（α2）.The safety stage height（h）on top ore layer increased with the increase of the ore layer space（a）,ore layer,near hanging wall,angle（α1）and hanging wall movement angle（β2）.The influence of various factors on H and hflows the in sequence ofα2aγ1,aα1（β2）.This study provided a reference basis for mining safety stage height selection on multi-layer deposit.
