The temporary support equipment on the inner ring can provide supplementary support for the parts that the temporary support equipment on the fixed working platform fails to provide initial support; 2. Multiple excavation devices are arranged on the rotary working platform. Multiple excavation devices work at the same time, which can speed up the construction efficiency, and the excavation equipment can be used for auxiliary slag feeding; 3. During excavation operations, the rotary mechanism can drive the slag discharge system to rotate on the working surface to discharge slag, so as to improve the slag discharge efficiency, which solves the problem that the existing host system can only be limited to a certain point on the working surface for slag discharge and cannot achieve all-round slag discharge.
