      <abstract xml:lang="ru">
        <p>Практика сооружения вертикальных стволов буровзрывным способом в условиях комбината "Ростовшахтострой" показывает, что совершенствование параметров буровзрывных работ позволяет уменьшить отклонение фактических сечений от проектных. Вместе с тем это не сопровождается уменьшением неровностей по родных стенок ствола, а разрушение пород в обнажениях остается еще значительным.</p>

        <p>The practice of construction of vertical shafts by the drilling and blasting method in the conditions of the combine “Rostovshahtostroy” shows that the improvement of parameters of drilling and blasting works allows a reduction of the deviation of actual cross‑sections from the design. At the same time this is not accompanied by a reduction of irregularities of the rock walls of the shaft, and the destruction of rocks in exposures remains still significant.</p>
