| Abstract: | With the collection of the prophase data and the hole deviation problem,the paper introduced the formation situation and orebody features of Sunjiazhuang mining area in Shanxi.Analysis was made on the hole deviation and the causes with the summary on change of borehole deviation and the features in this mining area.The borehole structure,drilling tool grading,case selection,primary directional drilling and deviation prevention measures were described.The drilling construction effect showed that the primary directional drilling and deviation prevention measure were feasible and reasonable. |
