tailings tailings storage guidelines and standardsin july , the mining residue regulations (mrr) was established by the department of environmental affairs (dea) to control mine waste dumps, stockpiles and tailings storage. chile in chile the servicio de minas del estado is responsible for regulating tailings impoundment projects as well as the safety of the workforce employed to managewaste management for mine solid wastethe mining regulations (dumps) promulgated in the early 70's have their emphasis on safety and the integrity of mining operations. mine waste disposal methods (tailings dams) have affected the environment in which they are situated in many ways dam failures have damaged not on 1 y property,· 1 i fe loss, po ut i onfile size 293kbreading effects of mining geologythese ponds are secured by impoundments (dams or embankment dams). in 2 it was estimated that 3,500 tailings impoundments existed, and that every , 2 to 5 major failures and 35 minor failures occurred; for example, in the marcopper mining disaster atmodelling tailings dams and mine waste dumps failuresthis paper presents a depthintegrated model that can be used to simulate the flowslides, mudflows and debris flows that are caused by the failure of tailing dams, mining waste dumps and other similar structures. the sliding mass is first determined using a coupled elastoplastic finite element code and a suitable constitutive equation.autonomous sensors monitoring tailings dams and spoil dumpsautonomous sensors monitoring tailings dams and spoil dumps. challenge. mine tailing facilities contain the waste material removed during the mining process, whereas spoil managements house the remains after the processing and removal of precious materials. where spoil contains only overburden or waste rock, due to the techniques used throughout the extraction process, tailings are usually a slurry of finemine waste dumps \u mi 310.pptx mine waste dumpsdump geometry and stacking method. the geometry of the waste dump depends largely on the dumping method, as well as the topography of the site the two common construction methods for waste dumps include end dumping and stacking material in lifts or layers. if the material is enddumped from the crest of the waste dump, the material will flow down the slope and rest at or near the angle oftechnical report design and evaluation of tailings damswhile this report discusses general features of tailings dams and impoundments, actual designs for tailings disposal are highly sitespecific. design depends on the quantity and the individual characteristics of the tailings produced by the mining and milling operation, as well as the climatic, topographic, geologic,
