DIN EN 16907-7 PDF Download

The DIN EN 16907-7 standard provides recommendations for the hydraulic placement of extractive waste. It covers all aspects of dams, confining embankments, or other structures that contain, retain, confine, or support such waste on the surface in a terrestrial environment.

The standard focuses on the characterization of extractive waste for hydraulic placement, both as part of the confining embankment and for safe storage. It sets minimum requirements for data acquisition before the design and execution stage of a hydraulic fill project. The document also provides guidelines for selecting the appropriate type of confining embankment and construction materials, and outlines principles for the design and execution of the hydraulic fill project from pre-deposition through operation to closure and rehabilitation.

Furthermore, the standard includes guidelines for monitoring and quality control at all stages of the hydraulic fill project to ensure long-term safety and stability. It emphasizes compliance with good regulatory and engineering practices but does not specify detailed design elements of a hydraulic fill project. The standard acknowledges that similar techniques may be applicable to the hydraulic placement of materials in non-extractive industries when no other European guidance is available.

However, it is important to note that this standard does not address the design of earth structures in terms of safety and serviceability. Factors related to safety and serviceability are governed by other relevant standards, such as EN 1997 (series) (Eurocode). The standard assumes that the earth structures have already been properly designed. Additionally, this document does not apply to landfill, dredging, or the hydraulic filling aspects associated with grouting.
