摘要: 露天转地下崩落法采矿时露天坑覆盖层渗流量的大小关系到井下回采放矿的安全。通过分析矿区降雨强度、露天坑汇水面积以及覆盖层本身的结构特性,研究这些因素与露天坑覆盖层渗流量的关系,对减小井下水量,确保采矿安全意义重大。

关键词: 露天转地下, 覆盖层, 渗流量

Abstract: With the caving method from open pit to underground mining,the overburden seepage discharge in the open pit relates to the safety of underground mining. Through the analysis of rainfall intensity,the catchment area of the open pit and the structural characteristics of overburden,the relationship between these factors and the seepage discharge of open pit overburden is studied,which is of great significance to reduce the underground water and ensure the mining safety.

Key words: Transferring from open pit into underground, Overburden, Seepage discharge
