      <abstract xml:lang="ru">
        <p>Ритмичность работы карьеров Заполярья зависит от многочислен­ных факторов и прежде всего от суровых климатических условий, влия­ние которых приводит к снижению производительности карьеров и нару­шению ритма их работы. Для учета суровости климата вводятся попра­вочные коэффициенты к нормам выработки в различные периоды года. Однако сезонные колебания в целом изучены недостаточно, хотя законы сезонности очень важно учитывать при планировании и организации производственных процессов. С другой стороны, на карьерах Заполярья очень важно использовать благоприятные периоды года для интенси­фикации горных работ.</p>

        <p>The rhythmicity of work of quarries in the Polar region depends on numerous factors and, first of all, on severe climatic conditions, the influence of which leads to a decrease in the productivity of quarries and violation of the rhythm of their work. To take into account the severity of the climate, correction factors are introduced to the production rates in different periods of the year. However, seasonal fluctuations in general are insufficiently studied, although the laws of seasonality are very important to take into account when planning and organizing production processes. On the other hand, at the quarries of the Polar region it is very important to use favorable periods of the year for intensification of mining operations.</p>
