Abstract: Taking A Mining Area as an example, this paper analyzed the application of inclined hole construction technology in
the iron mine of the project, expounded the designed drilling structure, and put forward the parameters of bit pressure, rotation
speed and reasonable pump volume. At the same time, in the construction process, it required mud purification, analyzed the key
technology in the construction process of inclined hole, that was accurate measurement of inclined hole, to ensure the concentric
installation of drilling tower, drilling, opening broken layer coring, which provides a certain reference for the application of
inclined hole construction technology in the mining area.

Key words: inclined hole of iron mine; drilling parameters; drilling structure; mud purification
