Abstract: Based on the reconstruction project of the Gorno-Shorsky Branch of JSC «Evraz ZSMK» developed by JSC "Giproruda" to maintain the production capacity of the enterprise of 6 million tons per year, it is necessary to deepen Skipovoy shaft from the mark + 115 m to the mark – 85 m. When sinking the active hoisting shaft, to protect workers in its sunk part from the possible fall of vehicles or their contents, it is necessary to construct safety devices. The analysis of domestic and foreign experience has shown that over the past 30 years, nobody whether it is in Russia or abroad has been doing any studies in the development of new designs of safety devices for deepening vertical shafts in Russia, and the latest methodological guidelines for their design were developed and implemented in 1979 by VNIIOMSHS and in 1985 by the Krivoy Rog Mining Institute. The results of the studies of dynamic loads impact for the protective equipment construction under shafts sinking equipped by skip winding are given in the paper.
