酸刺沟煤矿起雾原因分析及解决措施

首先对巷道起雾进行了理论分析,然后通过测定起雾地点4113辅运顺槽的湿空气参数,具体分析了酸刺沟煤矿部分巷道起雾原因.分析结果表明,起雾主要与巷道湿度、温度、巷道地势变化和巷道漏风有关:巷道中潮湿环境增加了湿空气的含湿量,逐渐下降的温度降低湿空气饱和水的能力,最终形成起雾现象;巷道地势变化和漏风使得湿空气焓值不断变化,从而导致了雾气集聚.根据影响起雾的因素,井下应尽量对雾气影响严重处祛湿增温,并加强通风系统管理和优化,以消除雾气;对无法消除雾气的地点,应增加起雾巷道的可见度,并添加警示标志,以消除起雾对安全生产的影响.

Study on the causes and solutions of the fog in the Suancigou coal

The fog in the roadway not only affects the production and transportation of the colliery, but also reduces the safety coefficient of the minors. First, this paper studies the theory of the cause of fog and determines the parameters of the wet air in the 4113 auxiliary transport roadway where is misting. The result shows that the fog is mainly caused by humidity, temperature, terrains and air leakage in the roadway. Because the humid environment in roadway increases the humidity content of moist air, and downdraft temperature reduces the ability of imbibe water, the fog comes out in the roadway. The enthalpy of moist air changes caused by terrain changes and air leaks causes the mist concentration. The mine should warm the moist air, decrease the humid environment, strengthen the management and optimize the ventilation systems to eliminate the fog, and the mine should increase the visibility of roadway, add warning signs to reduce the impact on the safe production by fog.
