中文摘要：

安微淮南潘北煤矿–580m水平探4孔与ES1C^3上3-1孔在疏放太原组灰岩水时带有臭鸡蛋气味,且水流过程中伴有白色絮状漂浮物.通过采集水样,测试了出水孔水质及气体,分析了其形成原因.结果表明：气体为H2S,两出水孔的水质均具有低SO2–4、高HCO–3、弱碱性特征,白色絮状物为有机质和钙、镁物质的结合,该异常现象是脱硫酸与脱碳酸共同作用的结果.为及时处理异味对井下作业环境的影响,采用纳米二氧化钛–紫外光催化氧化法在室内对水进行硫化氢去除试验,其去除率为80%~90%,效果显著.

英文摘要：

When drained from horizontal drainage holes 4 and ES1C33 -1 in aquifer of Taiyuan Formation limestone, at–580 m level in Panbei coal mine, water taste smells like rotten eggs , and moreover there is white flocculent flotage. Bycollecting water samples, the water quality and gas were tested, and the genetic mechanism was analyzed. The resultsindicate that the gas in the water is H2S, and the water from two holes has similar characteristics such as low SO2–4 , high HCO–3,lower salinity and low alkalinity, and white flotage material is composed of organic and calcium– magnesium material .Such anabnormal phenomenon was resulted from actions of desulfation and decarbonation . In order to deal with harmful gases undermine working environment immediately, experiment on disposing H2S has been performed with nanometer titanium dioxide（TiO2） and UV light catalytic oxidation. The results show that removal ratio of H2S is close to 80~90 percent.
