        <p>Одним из известных методов определения граничного коэффициен­та вскрыши при открытых разработках является метод сравнения до­пустимой себестоимости полезного ископаемого, рассчитанной с учетом всех капитальных затрат на добычу и переработку сырья и извлекаемой ценности, с фактическими себестоимостями добычи руды и удаляемой вскрыши, принимаемыми по аналогам...</p>

        <p>One of the well-known methods of determining the limit overburden ratio in open pit mining is the method of comparing the allowable cost of the mineral, calculated taking into account all capital costs of mining and processing of raw materials and recoverable value, with the actual cost of ore extraction and removed overburden, taken by analogues...</p>
