Open pit operators are facing a number of challenges in the area of blasting and blasting processes such as wall control quality of fragmentation explosives consumption and vibration Remaining financially viable is one of the most significant objectives for mining professionals as they work through the blasting challenges within the mining chain of processes This objective
Mining and milling Markus Piro Ksenia Lipkina in Advances in Nuclear Fuel Chemistry 2020 Open pit mining Open pit mining refers to mining directly on the ground surface thereby producing an open pit This method is practical and cost effective when the uranium ore is located near the surface within 100 m Underground mining and ISL methods may be
Sustainability of the open pit mining and technical system MTS is one of its key goals in the changing conditions of the external and internal environment All MTS s subsystems must function in concert to achieve this goal The structure of the MTS is formed by many subsystems and elements which are evaluated by a significant number of indicators A
The share of in situ mining is expected to rise in the future it is estimated that 20% of total raw bitumen reserves can be recovered via open pit mining and 80% via in situ mining Open pit mining is performed when the sands deposits are found at less than 75 m below the surface Natural Resource Canada 2016a When the overburden is deeper
Approximately 10% of the world s energy related anthropogenic greenhouse gas GHG emissions stem from the primary production of minerals and metals Huo et al 2023; Yokoi et al 2022 Projections based on current trends suggest that by 2030 the escalation of iron ore open pit mining activities to meet the global demand for raw materials could
The proposed model was verified in Sungun Copper Mine as large scale open pit mining Analyses showed that Social Relationship Economic Growth and Productivity and Flora and Fauna Landscape and Social Infrastructure Developments are the two sets of three top sustainable development sub criteria which contributed the most positive
Open pit mining holds significant economic importance for numerous countries According to Pietrobelli et al and Ericsson and Lof this is evidenced by the Mining Contribution Index MCI Wr in various regions including West Northern Southern and Central Africa Oceania Central Asia and Latin regions where mining plays a
To achieve stable pit wall slopes it is imperative to obtain a fair knowledge of the rock mass characterisation before designing the pit Insufficient knowledge of the competency of the country rock could lead to using unsupported slope configuration in the design process which can consequently lead to slope failure In this study the geomechnical properties of the
Digitalisation in mining refers to the use of computerised or digital devices or systems and digitised data that are to reduce costs improve business productivity and transform mining practices
Environmental costs can have a significant impact on the economics of a mining project and thus it is crucial to determine the environmental costs per ton of ore in the early stages of mining activities especially during feasibility planning and design stages and compensating for the environmental impacts of open pit mining activities
Alford C G and Whittle J 1986 Application of the Lerchs—Grossmann Pit Optimization to the Design of Open pit Mines in AusIMM/IE Aust New man Combined Group Large Open Pit Mining Conference October 1986 pp 201 7 Google Scholar Annels A E and Hellewell E G 1988 The orientation of bedding veins and joints in core; a new method and
4 Although the basic concept of an open pit is quite simple the planning required to develop a large deposit for surface mining is a very complex and costly undertaking At one mine it may be desirable to plan for blending variations in the ore so as to maintain as nearly as possible a uniform feed to the mill At another operation it may be desirable to completely
EXTRACTION; REHABILITATION; TYPICAL OPEN CUT GRADES; REFLECTION QUESTIONS; Contributors and Attributions; Open pit mining or open cast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or This form of mining differs from extractive methods that require tunneling into the earth such as
The curve reaches its maximum at pit limit V11 meaning that when maximizing the total profit to the mining Xiao chuan XU et al/Trans Nonferrous Met Soc China 31 2021 3847∠3861 3857 Fig 7 Social benefits of geologically optimal pit limits Fig 8 Economic profits total ecological costs and total social benefits of geologically
Blasting is the most commonly used method in open pit mining operations Its quality and efficiency not only affect the overall productivity of the mining process but also determine the economic benefits for the enterprise Prediction and optimization before blasting are crucial means of controlling blasting outcomes which has prompted a
