Abstract: Based on the reconstruction project the Mountain Shoria branch of OJSC «Evrasruda» developed by JSC "Giproruda" to maintain the production capacity of the enterprise 6 million tons per year «Skipovoy» shaft It is necessary to deepen from the mark + 115 m to the mark - 85 m. Due to the time of reconstruction had to be compressed, In this regard, after scientific literature analysis, analysis of existing methods of shafts deepening and types of safety devices analysis, the staff of CUFandM department of T. F. Gorbachev KuzSTU together with specialists from the design organization LLC “SibGorKompleks Engineering” developed and implemented a new design of protective device for the deepening of vertical shafts in the conditions of operation of the operating lift Analysis of domestic and foreign experience has shown that over the past 30 years, the development of new designs of safety devices for deepening vertical shafts in Russia, or abroad nobody has and the latest methodo-logical guidelines for their design were developed and implemented in 1979 VNIIOMSHS and in 1985 the Kri-voy Rog Mining Institute. The article presents the results of studies of the effect of dynamic loads on the construction of protective device in the deepening of skip shafts. Based on the methodology for calculating the basic elements for force at emergency unloading of skips, the dependencies allowing to determine the value dynamic impact on the main structural elements of protective device with full overlapping sections of the vertical shaft which can be used when justifying the construction parameters Wedge-type protecting apron

Key words: vertical shaft shafts sinking wedge protective bunton dynamic load skips unloading
