According to the State Coal Mine Safety Supervision Bureau (coal mine refuge Pilot Project Basic Requirements) (Coal Safety Supervision Division Office 2010 Article 9 No.) and the State Coal Mine Safety Supervision Bureau on (construction to improve coal mine safety risk Six systems Notice) (total coal screening equipment 146 No.) requirements; isolation gate is not less than the reverse throttle standards; isolation doors and walls not less than **** The standard library wall.
Isolation doors and closed doors are made of multi-point perimeter fastening structure, seal dual channel U -Groove seal type. Open and flexible, reliable sealing.
in 2012 year 3 Month time through (national Chongqing mine production safety equipment inspection and testing center ) Antiknock prototype testing, the indicators in full compliance with (the pilot construction of underground mine refuge basic requirements) requirements. And has been widely used in the construction and use of coal mine refuge chamber permanent and temporary refuge chamber.
