以安徽省淮北煤田孟庄煤矿3,5和6煤层为研究对象,系统刻槽采取3个煤层的15个样品,采用仪器中子活化法(INNA)测试了煤中砷和稀土等元素的含量,研究了砷在3,5和6煤层的空间分布,分析了砷与灰分、稀土元素、硫以及含量之间的相关性。研究结果表明:孟庄煤矿煤中的砷的含量略高于与华北-石炭二叠纪煤中砷的算术平均含量,低于全国煤中砷的平均值;煤中的砷与灰分含量、稀土元素以及铝含量之间存在较好的相关性,表明研究区煤中的砷与陆源存在一定的关系,无机组分的砷可能主要被粘土矿物吸附。
Taking the No.3 and No.5 coal seams of Mengzhuang Coal Mine, Huaibei Coalfield, Anhui Province, as the research object, 15 samples of 3 coal seams were systematically grooved. The content of arsenic and rare earth in coal was tested by INNA , Studied the spatial distribution of arsenic in the coal layers 3, 5 and 6, and analyzed the correlation between arsenic and ash, rare earth elements, sulfur and their contents. The results show that the content of arsenic in coal of Mengzhuang Coal Mine is slightly higher than the arithmetic mean of arsenic in coal of North China-Permian Permian and lower than the average of arsenic in coal in China. The contents of arsenic and ash in coal, There is a good correlation between the element and the aluminum content, indicating that the arsenic in the coal in the study area has a certain relationship with the land source. The arsenic in the inorganic component may be mainly adsorbed by the clay minerals.
