      <abstract xml:lang="ru">
        <p>С середины 60-х годов в отечественной и зарубежной практике начинает развиваться и совершенствоваться новое прогрессивное направление ведения открытых и подземных горных работ, в основе которого лежит контурное взры­вание шпуровых или скважинных зарядов ВВ.</p>

      <abstract xml:lang="en">
        <p>Since the mid 1960's in domestic and foreign practice begins to develop and improve a new progressive direction of open pit and underground mining, which is based on the contour explosion of borehole or borehole explosive charges.</p>
