针对辛置煤矿矸石山前期治理效果不佳的问题,在分析矸石山重力热管的结构与工作原理基础上,通过对重力热管工质种类及充填比例的优化,设计了热管工质研究实验系统,比较甲醇、乙醇、己烷三种工质对热管性能的影响,提供一种针对工质种类的实验分析方法。充填甲醇工质的重力热管性能优于乙醇和己烷,且甲醇热管稳定运行阶段的最佳充填比例为36%。现场试验中,通过30d的温度监测,对比甲醇热管与乙醇热管的治理效果,甲醇热管温度下降9.94%,乙醇热管温度下降5.28%,第30天时两者的温差为15℃,辛置煤矿矸石山后期施工时,应用甲醇热管会进一步提升治理效果。

In response to the problem of poor early governance effect of the gangue mountain in Xinzhi Coal Mine, based on the analysis of the structure and working principle of the gravity heat pipe in gangue mountain, and through the optimization of the working medium types and filling ratios of the gravity heat pipe, an experimental system for studying the heat pipe working medium is designed to compare the effects of three working medium such as methanol, ethanol, and hexane on the performance of the heat pipe, and provide an experimental analysis method for working medium types. The performance of gravity heat pipes filled with methanol working medium is better than that of ethanol and hexane, and the optimal filling ratio for stable operation stage of methanol heat pipes is 36%. In the on-site experiment, through 30 days of temperature monitoring, the governance effects of methanol heat pipes and ethanol heat pipes are compared. The temperature of methanol heat pipes decreases by 9.94%, and the temperature of ethanol heat pipes decreases by 5.28%, the temperature difference between the two on day 30 is 15℃ . During the later construction of the gangue mountain in Xinzhi Coal Mine, the application of methanol heat pipes will further improve the governance effect.
