      <abstract xml:lang="ru">
        <p>В механизмах ударно-вращательного бурения (пневмо- и гидроударниках и т. п.) передача энергии для разрушения горной породы осуществляется от поршня-ударника или непосред­ственно на породоразрушающий наконечник — долото, или через промежуточное звено — буриль­ную штангу, колонковую трубу — на буровую коронку.</p>

      <abstract xml:lang="en">
        <p>In the mechanisms of percussive-rotary drilling (pneumatic and hydro-impactors, etc.) energy transfer for rock destruction p is carried out from the piston-impactor or directly to the rock-destroying tip - bit, or through an intermediate link - drill rod, drill pipe - drill bit.</p>
