Recycled Materials as Backfill for Mechanically Stabilized Earth (MSE) Walls Posted on April 28, 2017 by apakes Granular materials are often the product of construction operations, industrial operations, or dredging operations in rivers, ports, and harbors.
Backfill material types and processes are numerous but generally utilize a blend of binders, process water and aggregates ranging from rock, crushed aggregates, gravel and quarried sands to tailings left over from mineral processing to provide the required restraint to enable massive strategic support for the underground extraction sequence of the ore.
The hesitation to implement these systems is often due to unfamiliarity and unknowns. The view that paste technology is a bit of a black box is warranted in that the evaluation requires an integrated knowledge and experience of technical and operational nature with respect to mineral processing, mining, geotechnical and environmental engineering.
Backfill process utilizes the ore tailings as an economical materials for backfilling the underground voids in the mine. In this mineral processing operation, volumes of fine mud should be removed after the valuable mineral materials have been abstracted.
Aug 06, 2020· Tailings are industrial by-products generated during the exploitation of mineral resources. Partly used for backfill mining, a large amount of tailings are stored as solid waste in surface tailing ponds. Waste tailings are a source of pollution as well as accidents , , , . With the deepening of underground resource mining, mining activities are becoming systematic with large scales.
Processing operations may limit or enhance the opportunities for using tailings and other waste products as a backfill material. Backfilling is a truly multi-disciplinary process and requires the informed involvement of mining, metallurgical, engineering and environmental specialists.
Backfill is usually considered a necessary evil that contributes little to the principal objective of the operation, ore production. Consequently, it is relegated to an auxiliary role in the operation with minimal equipment and resource allocation in planning and is only superficially considered during feasibility studies. In many mines, the inadequacy of the design and...
This study demonstrates the feasibility of recycling lead–zinc tailing (LZT) as a cemented paste backfill (CPB) by considering the mechanical properties and environmental effects, thus providing an approach for safe and environmentally friendly treatment of LZT. First, the mechanical properties of CPB samples were tested. When the cement/tailing ratio was 1:6 and the slurry concentration was ...
