On basis of this model, the modeling methods and modeling flow were discussed based on data source of geological observation, drillhole, ichnography and section map.
在此基础上，探讨了在基于地质观测数据、钻孔数据、平面图数据、剖面图数据的断层建模方法和建模流程。

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.
At Yaoqiao coal mine, once and successful shaft washing using hydrochloric acid is made in the drillhole aquifer stuffed by the Permian system Taiyuan group NO. 4 lime, good result has been obtained.
