金川二矿风流热力参数规律分析

Analysis on Variety Regularity of Airflow Thermal Parameter at Jinchuan No.2 Mine

在对金川二矿风流热力参数测定的基础之上,详细地分析了风流焓值、含湿量、相对湿度、露点温度和空气密度随风流路线的变化规律,掌握了金川二矿高温矿井的热、湿源的类型及分布状况。金川二矿的主要热源是井筒段的风流自身压缩热、运输中矸石散热、暴露时间较短的围岩散热及机电设备散热;主要湿源为井筒段的淋水加湿、涌水加湿和开采盘区内的喷雾降尘加湿。针对具体的热、湿源提出了治理措施。

In the base of determination of air-flow thermal parameters at Jinchuan No.2 mine,the variety regularity of airflow enthalpy,moisture content,relative humidity,dew point temperature and air density with airflow route,and the types and distribution of heat and humidity source at high temperature mine of Jinchuan No.2 mine are grasped.In the JinChuan No.2 Mine,the main heat source is self-compressed hot of air flow,heat dispersal of waste gangues in transportation,wall rocks and mechanical equipment in shaft;The main humidity source is the watering,the water gushing and the spraying for dust control in panel.In view of these heat and humidity sources,some control measures are put forward.
