摘要
在对济宁2号煤矿三采区冬季风流热力参数测定的基础上,详细分析了自地面流向采掘工作面的过程中,风流的温度、焓、含湿量和相对湿度的沿程变化规律。通过分析,掌握了井下热湿源分布情况和采掘工作面热害环境状况。由于,冬季高温高湿矿井的风流热力参数变化规律和夏季井下采取人工制冷措施时冷风流热力参数的变化规律相类似;所以,为济宁2号煤矿夏季采取人工制冷措施提供了可靠的参考资料。在结论部分提出了济宁2号煤矿三采区夏季采取人工制冷措施时应注意的问题。
This article detailedly analyzes the change rule of temperature, enthalpy, moisture content and relative humidity of airflow in the course of it flowing from ground to working face on the basis of measuring the heat parameters of hiemal airflow at No. 3 excavating section of No. 2 coal mine in Jining. By analysis, the distribution of heat and humidity source and the hot environment of working face are grasped. The change rule of the heat parameters of airflow in high temperature and high humidity mine in winter is similar to that of the heat parameters of cold airflow in summer after taking man-made refrigeration measures, so this article has offered a dependable reference for taking man-made refrigeration measures at No. 2 coal mine in jining. In the conclusion of this article, we put forward some problems, which should be paid attention to while taking manmade refrigeration measures in summer at No. 3 excavating section of No. 2 coal mine in jining.
