The invention provides a steel derrick used for permanent lifting and also used as a kilometer vertical shaft full face heading machine. The steel derrick comprises a main leg, an auxiliary leg, a supporting platform, a lower head sheave platform for shaft sinking, an upper head sheave platform for shaft sinking and the like. The supporting platform is connected to the middles of the main legs and the auxiliary legs. The lower head sheave platform for shaft sinking is connected to the middle parts of the main leg and the auxiliary leg and positioned above the supporting platform; the upper head sheave platform for shaft sinking is connected to the middle parts of the main leg and the auxiliary leg and is positioned at the upper part of the lower head sheave platform for shaft sinking; the lower head sheave platform for permanent lifting is connected to the middle of the main leg and the top of the auxiliary leg and located on the upper portion of the upper head sheave platform for shaft sinking. The upper head sheave platform for permanent lifting is connected to the middle of the main leg and located on the upper portion of the lower head sheave platform for permanent lifting. The lifting beam platform is mounted at the top of the main leg; the two groups of derrick legs are respectively connected to two ends of the bottoms of the main leg and the auxiliary leg. The device can be used for permanent lifting, shaft sinking construction and shaft equipment installation at the same time, the shaft mouth occupation time is shortened, and the engineering investment is saved.
