underground space distribution的意思|示意

The practice demonstrates that high density electrical technique could precisely predict the space distribution characteristics of complicated underground cavities, and is worth to be applied further.

实践证明，采用高密度电法能够高精度预测地下复杂采空区的空间分布特征。

The model considers the mining order and the grade distribution in different deposit sections and has realized the time-space dynamic combination of the cutoff grade in underground mining.

该模型考虑矿体的开采顺序和矿床不同区段的品位分布，实现了地下开采边界品位在时间和空间上的动态结合。
