The invention provides an iron tower capable of coping with uneven settlement in a mining area and a centering method of the iron tower. The iron tower comprises a tower body, tower feet and a foundation, wherein the lower ends of the tower feet are connected with the foundation through shoe plates; two parallel connecting lugs are arranged at the upper ends of the tower feet, a row of uniform connecting holes are formed in the connecting lugs, grooves which are parallel to the outer side of the tower body and matched with the connecting lugs are formed in joints of the tower body and the tower feet, thickness of the tower body outside the grooves is equal to the distance between the two connecting lugs, and through holes which are matched with the connecting holes and fewer than the connecting holes are formed in the tower body outside the grooves; a horizontal sensor is arranged on a beam of the tower body; a space coordinate locator is arranged on each tower foot; binding lines arefixed on extension lines at the upper ends of the tower feet on the tower body, and the other ends of the binding lines wind around a winding shaft on the tower body. The iron tower is particularly applicable to areas with uneven settlement, and is simple and reliable to center after settlement.
