Abstract RU 2186219 C2

FIELD: mining industry; applicable in ventilation systems of deep opencasts dead zones. SUBSTANCE: flexible ventilation pipeline includes separate links with internal preset hole area. Pipeline is made in the form of inflatable balloons filled with lifting gas to insure floatability of assembled pipeline in ambient atmosphere. Inflatable balloons are tightly connected to one another with bending in points of link joints. Inflatable balloons are connected via reducer to source of compressed lifting gas and provided with flexible adapting members for passing of lifting gas to balloons. EFFECT: higher reliability. 3 dwg
