      <abstract xml:lang="ru">
        <p>Важнейшими показателями кондиций на слюдяные месторождения являются минимальное промышленное и бортовое содержания. До настоящего времени все подсчеты запасов слюды (флогопита и мусковита) производились по кондициям Главслюды МПС СССР, введенным в действие еще в 1950 г. Для месторождений флогопита и мусковита эти кондиции предусматривают следующее содержание по колотой слюде в расчете на минимальную выемочную мощность жил, равную 1 м, кг • см²/м³.</p>

        <p>The most important grade indicators for mica deposits are the minimum commercial and cutoff grades. To date, all reserve calculations for mica (phlogopite and muscovite) have been made according to the specifications of Glavsluda of the USSR Ministry of Communications, which were introduced as early as 1950. For phlogopite and muscovite deposits, these specifications provide for the following content of cleaved mica per minimum minable thickness of veins of 1 m, in kg·cm²/m³.</p>
