摘要 《煤矿安全规程》第445条,关于所有开关必须有"两防"功能的规定是一条易被忽视的条款。由于过去没有保障这一条款的技术装备,矿用开关无"两防"功能一直未被作为失爆对待。随着矿用开关两防锁的问世,对这一问题的认识也应相应提高,完全应该把矿用开关无"两防"功能视为失爆,并提出整治要求。 "Safety Regulations of Coal Mine"445th reading that all switches must have two to guard against is an easily neglected clause. Because lacking technical equipments to guarantee this provision in the past, it has not been treating as "no explosion-proof" that mine switches don't have "biguard" . Along with the mine switch biguardian lock, the understanding of this problem should enhance corresponding. It should be definitely regarded that mine switches don' t have "biguard" as no explosion-proof, and the improvement requests should be raised.
