      <abstract xml:lang="ru">
        <p>На карьерах РФ наиболее широко используются шарошечные буровые станки СБШ. Станки данного типа нуждаются в модернизации, в частности с целью повышения производительности бурения. Рассмотрен способ повышения производительности работы станка СБШ с помощью наддолотного ударника и проведена оценка влияния его использования на скорость бурения.</p>

        <p>The most widely used in the Russian quarries are SBSH roller cone drill rigs. Machines of this type are in need of modernization, in particular with the purpose of increasing the drilling efficiency. The method of increasing the productivity of the SBSH rig with the help of a top hammer and the effect of its use on the drilling speed are considered.</p>
