Overview

Mine workers in mines have to be supplied with fresh air. The air flows are guided and controlled by means of air regulation systems. Air doors are openings in these structures that are used for the passage of people (travel way) or for production (haulage tracks). This standard specifies the safety requirements for double-wing type doors with pressure reduction for the travel way in underground coal mines. They are used in air regulation systems for safe travel. Air doors complying with this standard are installed separately from the haulage track doors. The national interests in the preparation of the standard have been represented by the committee NA 060-15-06 AA "Bewetterungsanlagen" ("Mine ventilation systems") at the Section Mining equipment of DIN Standards Committee Mechanical Engineering (NAM). Representatives of the manufacturers and users of mine ventilation systems and of the employers' liability insurance associations were involved in the preparation.
