      <abstract xml:lang="ru">
        <p>На рудниках комбината "Апатит" как правило верхняя часть рудных залежей выходит на дневную поверхность. При подземной разработке блоков верхних горизонтов нередко наблюдается самообрушение массива, смерзание отбитой руды, разброс ее взрывом. Это приводит к большим потерям руды ...</p>

        <p>At Apatit mines, as a rule, the upper part of ore deposits is exposed at the day surface. During the underground development of blocks of upper horizons, self-collapse of the massif, freezing of the beaten ore, and scattering by explosion are often observed. This leads to large losses of ore ...</p>
