Beschreibung
Zusammenfassung:	mining industry. SUBSTANCE: invention refers to facilities connecting flexible ventilation mine pipes intended for installation in mines, pits and tunnels in methane-laden atmosphere. Connection of sections of flexible ventilation pipe-line includes enclosures of adjacent sections with double rings built-in their folds on one end and with ordinary rings built-in on other end inserted one into another. Ordinary ring has smaller diameter than double ring whose diameter is same as of enclosure. EFFECT: increased strength and reliability of connection of sections of flexible ventilation pipe-line.
