| 中文摘要:湖南道县一个矿区，铁锰矿体储量约2200万t。由于复杂的水文地质和工程地质条件，从20世纪70年代发现后，一直没有开采。笔者通过多年大直径工程井的实践经验，查阅国内外资料后，提出了钻井-气举反循环法试开采的方法，并在现场进行了单孔开采试验，获得了比较满意的效果。以该矿体Ⅱ号矿为例，介绍了钻井-气举反循环法采矿的适用条件、工艺过程以及试采情况，并就以后大面积开采提出了若干技术措施。 |

| Abstract:There are about 22 million tons reserves of iron manganese ore body in a mining area in Hunan. According to the complicated hydrogeology and engineering geology conditions, a method of drilling air-lifting reverse circulation was put forward and single well test was made with satisfied result received. The paper introduced the mining process and production test with the field case. |
