摘　　要：花草滩煤矿原供热系统中燃煤锅炉现已老化、出力不足,且不符合当前环保政策要求,需淘汰锅炉并对原有供热系统进行改造。为了确保供暖、供热效果,保证煤矿安全生产与节能环保,分析了该煤矿现有余热资源及热负荷现状,提出了一种煤矿余热资源供热系统方案,并对该方案与电热水锅炉供热方案的投资运行费用进行了对比分析。结果表明,预计在3.3 a时,煤矿余热资源供热系统的总投资运行费用与电热水锅炉供热系统持平,此后每年节约运行费用67.58%。The coal-fired boilers in the original heating system of Huacaotan Coal mine are now aging and lacking in output,and fails to meet the requirements of current environmental protection policies.In order to transform the original heating system after the elimination of boilers,ensure the heating and heating effect,and guarantee the safe production,energy conservation and environmental protection of coal mines,the existing available high-quality waste heat resources and heat load status of coal mines are investigated and analyzed.According to the research results,a scheme of coal mine waste heat resource heating system is proposed and established,and the investment and operation costs of this scheme and the electric hot water boiler heating scheme are compared and analyzed.The research results show that the total investment and operation cost of the coal mine waste heat resource heating system is expected to be the same as that of the electric hot water boiler heating system in the 3.3 th year.Since then,the annual operating cost can be saved by 67.58%.
