PIPELINE FOR END CUT VENTILATION

摘要

FIELD: mining.SUBSTANCE: pipeline for end cut ventilation includes air intake, suction path tubes and devices for their joints connection. To increase the reliability and simplify its maintenance the air intake is made extension-type from several sections reducing in diameter towards the suction end. Note that air intake is mounted at the face end of the suction path. The devices for connection of the suction path pipe joints between themselves and air intake are made in the form of socket-and-spigot connections and quick-releasing clamps from flexible material embracing their joints.EFFECT: increase of reliability and convenience of pipeline maintenance.3 cl, 3 dwg
