摘要
为研究煤矿开采裂缝对土壤中重金属分布的影响,以山东省巨野矿区某开采工作面为例,分别沿着垂直裂缝方向于0,1,2,5 m处共采集19个剖面土壤样品进行研究分析。结果表明:研究区内土壤中7种元素均低于GB 15618-2018国家土壤标准的风险筛选值且在主裂缝处含量均较低。剖面中除As和Cr以外,表层中Cu,Pb,Zn,Ni含量均高于底层。土壤中Hg含量分布变化较大,在表层(0-10cm)以下含量较高。As,Cu,Zn,Pb在土壤中的分布均受土壤容重、孔隙度、砂粒含量和含水量的影响。
In order to study the influence of coal mining cracks on the distribution of heavy metals in soil,19 soil samples were collected from a mining face in Juye mining area,Shandong Province,at 0,1,2,5 m along the vertical direction of the crack and analyzed.The results show that the content of seven elements in the study area are lower than the risk screening value of the national soil standard GB 15618—2018 and their content in the main crack is low.The content of Cu,Pb,Zn and Ni in the surface layer is higher than that in the bottom layer in the profile except As and Cr.The distribution of Hg content in soil varies greatly and the content is higher below the surface(0~10 cm).The distribution of As,Cu,Zn,Pb in soil is affected by soil bulk density,porosity,sand and water content.
