Adopting survey technology of double-head water-stopped machine flowing high of upward-inclined drillhole rock destruction rules were surveyed, development height of water conducted zone was gained.
The experimental results show that a stable liquid distribution would be established after flowing through a given height of packed bed whether the initial distribution is uniform or not.
实验结果表明，不论液体初始分布的均匀性如何，液体流过一定高度的填料床后总会建立一个稳定分布。

A convenient and practical formula used to estimate the height water flowing fractured zone has been provided for underwater mining.
