Исследована эффективность применения забойки при осуществлении взрывных работ на Маломырском руднике. Эффективность оценивали посредством фиксации высоты вылета из скважины продуктов взрыва за определенный интервал времени. В качестве забойки использовали буровой шлам. Сравнительными испытаниями не подтверждена эффективность применения забойки из бурового шлама во взрывных скважинах.
