Abstract: The research on the quality standard of backfill in the field of construction has been increasingly going into the depth, but attention has not paid to the concentration of pollutants in backfill in the existing standards, so this problem should be considered in the formulation of relevant standards in the future.The quality standard of backfill in polluted sites is mainly determined by land use.In this paper, the authors mainly determined the quality control of soil reuse after remediation in the aspects of construction land and agricultural land, and provided suggestions for the establishment of quality standard of backfill in polluted sites.Sludge land use is mainly divided into four aspects:landscaping, land improvement, agriculture and forestry.At present, there is no evaluation standard for backfill quality of special mine both in China and abroad, and the relevant index system has not been formed.The authors focused on the analysis of mine backfill types and quality evaluation indicators, mainly from the type of land reclamation, backfill soil nature and the aspect of backfilling depth, and hold that avoiding geological disasters and preventing the spread of pollutants constitute the core of mine backfill quality control.At the same time, the authors preliminarily established the process of evaluating the quality of backfill soil in mines based on the existing relevant standards and norms, in order to provide a theoretical basis for the establishment of the quality standard of backfill in mine and provide reference for the formulation of the relevant backfill standards in the future.
