      <abstract xml:lang="ru">
        <p>При сопоставлении данных разведки и эксплуатации на участках Сарбайского и Соколовского добычных карьеров установлено, что эксплуатационная разведка по сети 50x25 м мало уточняет данные де­тальной разведки, проведенной по сети 100x50 м. Вместе с тем на уча­стках обоих карьеров при детальной и эксплуатационной разведках незначительно занижаются запасы руд и содержание в них железа.</p>

      <abstract xml:lang="en">
        <p>When comparing the data of exploration and exploitation at the sites of Sarbaisky and Sokolovskoye mining pits, it was found that operational exploration on a network of 50x25 m does not clarify the data of detailed exploration, carried out on a network of 100x50 m. At the same time at the sites of both quarries at detailed and operational exploration slightly underestimated ore reserves and iron content in them.</p>
