      <abstract xml:lang="ru">
        <p>Рассматриваются результаты исследований ударных процессов, в том числе для системы поршень – боек – штанга. Энергия семейства ударных импульсов при ударе поршня с бойком на 10-20 % превышает этот показатель при ударе сплошным поршнем. По результатам стендовых исследований сконструирована и апробирована в условиях Кировского рудника ОАО «Апатит» конструкция перфоратора со сдвоенной ударной системой.</p>

        <p>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.</p>
