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 mineral 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 subsequent 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 standard therefore 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 and, in addition: - specifies minimum requirements for the data to be acquired before the design and execution stage of a hydraulic fill project; - provides guidelines for the selection of the type of confining embankment appropriate for the selected site; - provides guidelines for the selection and characterization of the construction materials; - establishes general principles on how to design and execute the hydraulic fill project from pre-deposition through operation to closure and rehabilitation; - provides 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 guidelines in order to comply with good regulatory and engineering practice. he 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, but notes that it is not applicable to landfill, dredging or the hydraulic filling aspects related to grouting.
