        <p>На рудниках комбината «Апатит», применяющих систему этажно­го принудительного обрушения, в блоках, отрабатываемых под пога­шенными ранее горизонтами, определение потерь руды усложняется вследствие перепуска в них отбитых некондиционных руд и потерь с верхних блоков. ...</p>

        <p>At the mines of Apatit Combine, using a system of storey forced caving, in the blocks mined under the previously extinguished horizons, the definition of ore losses is complicated due to the transfer of beaten substandard ore and losses from the upper blocks. ...</p>
