雁南煤矿井下热环境特征与风流温度预测

Underground thermal environment characteristics and prediction of air temperature in YANNAN coal mine

生产的机械化和开采深度的增加使得煤矿井下的温度日渐升高,矿井深部开采面临着不同程度的热害问题。针对雁南煤矿对通风路线上热环境参数进行测试,分析了通风路线空气的状态参数变化规律,并由此总结出矿井主要热湿源。运用风温预测模型对28#煤层二段后顺槽掘进工作面风流温度进行了预测,为矿井降温措施的实施提供基础数据。

Production of mechanization and the increasing mining depth of coal mine make the rising temperature in deep mining, mine is faced with the problem of thermal damage with different degree. Point to Yannan coal mine ventilation routes, the thermal environment parame- ters were tested, and analyzed the change law of air state parameters, and summed up the main mine heat and moisture source. Made the air tem- perature prediction to the tunneling working surface in the two section of 28#coal seam with temperature prediction model, and provided basic data for the implementation of mine cooling measures.
