The vertical and parallel relations of the trench with drill drift are summarized by the bottom structure disposal design on inclined orebody footwall.
A solution process of the equation of Ekman drift motion in infinite deep sea is given in this paper. Furthermore, the regularity of vertical distribution of drift velocity is discussed.
