    適用范圍
    This document gives recommendations for the hydraulic placement of extractive wastes and may be applicable to the following: — all stakeholders engaged in the deposition of extractive wastes using hydraulic placement techniques with respect to geotechnical and geochemical aspects of the investigation, engineering design, construction and operation of a mine waste facility and all associated monitoring activities; — those extractive industries involving the production of fine particulate wastes which, in the course of industrial processing, require to be stored in a safe, stable and environmentally acceptable location; — practitioners in non-extractive industries in fields where similar techniques may be applicable and for which no other European guidance exists. The scope of this document includes all aspects of a dam, confining embankment or other structure serving to contain, retain, confine or otherwise support such wastes on surface in a terrestrial environment. The overall framework for the standard and for each stage of a hydraulic fill project is shown in Figure 3. This document addresses the characterization of the extractive waste for the purposes of hydraulic placement in the MWF, both as part of the confining embankment and for safe storage. In addition the standard recommends: — minimum requirements for the data to be acquired before the design and execution stage of a hydraulic fill project; — guidelines for the selection of the type of confining embankment appropriate for the selected site; — guidelines for the selection and characterization of the construction materials; — general principles on the design and execution of the hydraulic fill project from pre-deposition through operation to closure and rehabilitation; — guidelines for monitoring and quality control of all stages of the hydraulic fill project to ensure long- term safety and stability. This document considers how to store safely a given material resulting from a preceding process. It does not define, establish or specify detailed elements of the design of a hydraulic fill project but provides overall recommendations in order to comply with good regulatory and engineering practice. The document recognizes that similar techniques may be applicable to the hydraulic placement of materials in the non-extractive industries where no other European guidance exists. This document does not consider the design of earth-structures in terms of safety and serviceability. These are ruled by EN 1997 (series) (Eurocode) and other relevant standards. This document assumes that the earth-structures have been properly designed. This document is not applicable to landfill, dredging or the hydraulic filling aspects related to grouting.
