This paper deals with: 1) The impacts caused by open stoping and sub-level caving in comparison to backfilling methods; 2) The approximate impact of backfill on dewatering strategies, and; 3) The environmental benefits of backfill mining The differences in mine drainage strategies are supported by case histories from various min
STRUCTURAL EXCAVATION AND BACKFILL - Section 802 Earthwork forms a part of the installation procedures of box culverts, retaining walls, foundations, and substructur In order to ensure an adequate foundation for such structures, backfill material must meet certain specifications and be compacted by acceptable methods to adequate density
Hence, mine operators are moving towards less water in the fill to decrease cement and binder consumption; Flow velocities in excess of 2 m/s are required to maintain a homogeneous dispersion of the fill components in the slurry; Paste Backfill Paste backfill is a high density backfill (>70% solids depending on SG)
Low energy consumption and high reliability Our heavy duty GEHO® pumps perform in a wide range of applications such as long-distance ore pipeline transport, mine dewatering and backfill, autoclave feed, reactor and digester feed, gasifier feed, thickened tailings disposal and biomass transfer
require dewatering facilities in the stop Paste fills typically have solids concentration greater than 70% by mass, contain binders and little or no water drains from the backfill after placement This paper presents a rational design approach for backfill distribution systems by considering the backfill ,
In the 1980s, mining companies began experimenting with better dewatering concepts, and adding cement to the tailings mixture to achieve a better consistency of backfill with some potential for enhanced ground support The term ‘paste’ was coined to differentiate this tailings product from the previous hydraulic backfill Paste fill was an
mining system to be concentrate upon to regulate the pumping process to increase the efficiency and reduction of pumping cost  In this respect, here, a review of literatures have been carried out on different methods of mine dewatering and its challenges, selection of pumps for
Treatment solutions include dewatering of the tailings with belt presses and using paste thickener technology (addition of cement) and processing of underflow tailings as part of the floatation process , The resulting paste was then pumped into abandoned mine cavities to be used as backfill material Related Equipment .

Dewatering Plants by Resources Gold Technology Dewatering Plants are designed to perform highly effective solid liquid separation for process water recovery while producing both thickened slurry for mine backfill operations and filter cake for transport to a surface fill operation
The differences in underground mines dewatering with the application of caving or backfilling mining methods Article in Mine Water and the Environment 13(2):1-19 January 1994 with 22 Reads
Dewatering / d iː ˈ w ɔː t ər ɪ ŋ / is the removal of water from solid material or soil by wet classification, centrifugation, filtration, or similar solid-liquid separation processes, such as removal of residual liquid from a filter cake by a filter press as part of various industrial process Construction dewatering, unwatering, or water control are common terms used to describe .

opening the South Crofty Mine (tin) in Cornwall with additional revenue streams from the storage of incinerator ash underground when mixed with tailings for backfill The concept should certainly be discussed more openly Paste Preparation – Tailings Dewatering The dewatering method for paste backfill made from run of mine tailings is normally
It can be placed in stopes with or without binder addition depending on the strength requirements for backfill Improved pumping technology, environmental concerns, and the need for a low cost/high strength fill in mines, are driving mine operators to consider paste backfill as a tailings management and mine backfill alternative
