摘要
针对跃进煤矿原岩温度高的现象,利用计算机的数值模拟技术,以跃进煤矿23070工作面的进风巷道为研究对象,建立合适的几何计算模型,研究矿井巷道内温度的变化情况,得出了巷道内温度的变化与进风温度、速度的关系模拟图。通过对这些关系模拟图的定性定量分析,总结出了在实际生产过程中巷道温度的变化与进风温度的具体关系,为矿井生产降温问题提供了可供参考的理论依据和技术措施。
Yuejin Coal Mine protolith high temperatures, the use of computer simulation technology, combined with the actual production Yuejin Coal Mine, selected 23070 working face into the wind tunnel as the research object, the establishment of an appropriate model of geometric calculation temperature inside the mine tunnel, the inlet air the rate of change of temperature between the tunnel to get the temperature and changed mimics. Through these relationships mimic diagram of the qualitative and quantitative analysis, summed up in the actual production process, the temperature inlet air temperature with a specific relationship, mine production problems, provided reference and theoretical basis of technical measures.
