        <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 to the day surface. During the underground development of blocks of upper horizons is often observed self-collapse of the massif, freezing of the beaten ore, scattering of its explosion. This leads to large losses of ore ...</p>
