摘　　要：为回收华亭原安口煤矿残留煤资源,采用煤炭地下气化技术对残留煤进行二次开采和发电利用,通过空气连续法、空气蒸汽连续法、空气蒸汽两阶段、富氧和纯氧蒸汽连续法等不同注气工艺对残留煤进行了地下气化试验,研究了残留煤在不同气化工艺时的产气和发电特性。结果表明:添加蒸汽和氧气均可提高煤气中有效组分含量和煤气热值;采用连续法和两阶段气化工艺,能够获得热值4.07～10.69 MJ/Nm3的煤气,可作为2×500 kW燃气发电机组的燃料气。通过气化指标对比分析和现场发电对比试验,确定了低富氧蒸汽连续法(O2体积分数32%)为匹配该燃气发电机组的合理气化工艺。In order to recover the coal resources left in previous Ankou Mine of Huating area, an underground coal gasification technology was applied to the secondary mining and the power generation of the left coal.The underground coal gasification experiment was conducted on the left coal with the air continuous method, air and steam continuous method, air and steam two stage method, enriched oxygen and pure oxygen-steam continuous method and different gas injection techniques.The gas production and power generation features of the different gasification experiments with the left coal were conducted.The experiment results showed that the effective component content and coal gas heat value could be improved with the steam and oxygen injected.With the application of the continues method and two stage gasification technique ,the coal gas with heat value of 4.07-10.69 MJ/Nm3 could be obtained and could be the fuel gas for 2×500 kW gas-fired power generation unit.With the comparison analysis of the gasification index and the comparison experiments of the site power generation ,the low enriched oxygen（ O2 volume fraction of 32%） steam continuous method determined would be a rational and economic gasification technique for the gas-fired power generation unit.
