Abstract
The results of studies of impact processes, including the system piston - striker - rod, are considered. The energy of the shock pulse family at the impact of the piston with the striker is 10-20 % higher than this indicator at the impact with the solid piston. Based on the results of bench studies, the design of a perforator with a dual percussion system was designed and tested in the conditions of the Kirov mine of ОАО Apatit.
