【摘要】 系统采集了淮南李咀孜矿不同煤层中的13个煤样,采用美国Leco公司生产的"AMA汞分析仪器"测定所采集到的煤样中汞的含量。分析结果表明:李咀孜矿煤中汞的含量范围为0.082～0.251(ug/g),处于中国煤中汞的含量范围之内(0.01～1.00ug/g);其算数平均值为0.177(ug/g),与华北石炭—二叠系和美国煤中汞的算数平均值相近(0.17ug/g),略高于中国煤中汞的算数平均值(0.15ug/g)。不同成煤期煤层中汞的含量有较大差别,由大到小依次为:上石盒子组、下石盒子组、山西组。更多还原

【Abstract】 13 coal samples is collected from different coal seams in the Lizuizi mine.The mercury content of coal samples is mensurated through the AMA mercury analytic instrument which is produced by American Leco Corporation.It is concluded that Hg values in Lizuizi coals range from 0.082～0.251ug/g,which is in the range of Chinese coals(0.01～1.00ug/g),the average value of mercury content for all the coal samples is 0.26ug/g,which is close to the Hg value from Permocarboniferous period coal of northern China and U.S.coals(0.17ug/g),and slightly higher than the average value of the Chinese coals(0.15ug/g).The mercury content has wide difference from coal seam of different Coalforming Periods,and it is higher from Shangshihezi Formation than from Xiashihezi Formation,much higher than Shanxi Formation.更多还原
