Yongjiu Coalmine Group set a mine shaft mast stand in 1996, for the Shuang steel derrick, divided into vertical and inclined frame two parts. The part of the upright frame is a steel frame structure, the bottom of which falls directly on the lock plate. The inclined frame is a diagonal double-column frame steel structure, the components are welded closed box-shaped sections, and the inclined frame columns are hingedly connected with the foundation. The bearing capacity of foundation is 210MPa, the basic intensity of earthquake is 6 °, and the derrick weighs 196.8t, height 36.3m and service life 88a. 1 problems
