Traditional open-pit mining boundary features fixed slope with benches and planar bottom.
传统的露天矿开采境界为固定帮有台阶、露天底平面型。

The stability of boundary pillar, which can be found across in mine shifting from open-pit to underground mining, is very important for safe production of underground mine.
境界矿柱稳定性分析是露天转地下矿山经常遇到的问题，对于矿山进行地下开采安全生产极其重要。
