主备通风机切换通风系统优化设计与应用

摘要

Most of the collieries in our country have gas and coal dust explosion accident,which is mainly cause by the deficiency or disorder of draft inside the mine.Especially for the high gas mine, which has reached the upper extraction limit,has deficiency in draft and high ventilation resistance,which caused the problems of deficiency in draft in the actual mining face inside the mine,and a high density of harmful gases like methane and carbon monoxide and hard to eliminate.As a result,it is necessary to check the safety and stability of ventilation system regularly,and perform reasonable optimal design,and to deal with the problem as soon as it is found. This paper performed optimal design to the main ventilation system of Tashan Colliery according to its actual situation of safety production so as to ensure the safety and stability of mine production.%本文根据挖金湾矿实际，对主要通风机切换操作时通风系统进行改进优化，解决了因主要通风机切换停风造成矿井瓦斯等有害气体升高、风量不足、系统紊乱的难题。
