Scope

Scope: This document specifies the terms and definitions, model naming, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage of fully servo automatic safety interlocking air doors for underground coal mines. This document applies to the manufacture of air doors with a wind pressure strength of less than 3,920 Pa in underground mine tunnels. These fully servo automatic safety interlocking air doors can block airflow, prevent airflow short-circuiting, and ensure the safe passage of vehicles and pedestrians. Main technical content: The fully servo automatic safety interlocking air doors for underground coal mines are designed to meet the requirements of automatic control of air doors under various working conditions in underground mines. They receive external control commands and use pneumatic, electric, and hydraulic methods to quickly open and close them. At the same time, they have the function of interlocking the opening and closing of multiple air doors, which can block airflow, prevent airflow short-circuiting, and ensure the safe passage of vehicles and pedestrians. This standard specifies the terms and definitions, model naming, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage of such air doors, and is applicable to the production and manufacture of air doors with a wind pressure strength of less than 3,920 Pa in underground mine tunnels.
