The proposed dump model concept has been applied to optimize the ultimate design of a waste dump in an open pit copper mine. Mine production plan shows that the East pit will deploy uneconomical waste material in an approximate amount of at least 515 million tonnes during its 15 years life-of-mine …
and search for an adaptive rule applicable to open pit mines. For this purpose, a stochastic truck dispatching and production simulation program is developed for a medium size open pit mine consisting of several production faces and a single dump site using GPSS/H software. Eight basic rules are modeled in separate program files.
The design of the slopes is one of the major challenges at every stage of planning and operation of an open pit mine. It requires specialised knowledge of the geology, which is often complex in the vicinity of orebodies where structure and/or alteration may be key factors, and of the material properties, which are frequently highly variable.
Mar 17, 2017· open pit mine design factors 29 Years Experiences Mining Jig Plant,Jig Machine,Gold Refining . When processing the open-pit mines, the saw-tooth wave jigger is a key machine with the.
Slopes in open pit mines must be considered as geotechnical structures. Therefore their design and implementation must be conducted with all consideration including technical, economical, environmental and safety issues.
One of the first steps in open pit mine design is the completion of a pit optimization analysis. Pit optimisation is used to define the most profitable pit shell (or nested pit shells) for a given set of economic parameters.
Jan 10, 2016· Open Pit Mine Planning and Design, Two Volume Set - Building on the success of its predecessor, this 3rd edition of Open Pit Mine Planning and Design has been both updated and extended, ensuring ...
E Contd.E. Pit design Overall slope of a pit depends on several factors of the pit slope: a) Geological disturbances like faults etc. b) Hydrological condition of strata c) Orientation of slip planes d) Nature of strata – i.e. hardness, material consolidation etc. e) Depth of workings f) Design …
Fig. 1, above shows an illustration of a Open Pit Surface Mine. The definition of a open pit mine is "an excavation or cut made at the surface of the ground for the purpose of extracting ore and which is open to the surface for the duration of the mine's life."
Design of Surface Mine Haulage Roads – A Manual By Walter W. Kaufman and James C. Ault ABSTRACT This Bureau of Mines manual for design of surface mine haulage roads covers such aspects of haulage road design as road alignment (both vertical and horizontal), construction materials, cross slope, and drainage provisions.
A design reliability of 80% is generally accepted in open pit design, which means allowing 20% of all wedges actually to fail. The accepted failure level determines the design bench angle.
Summary. This course presents an overview of the process for the design and management of slopes in open pit mines. Starting with a description of the information required to support a slope design and the methods of data collection, it progresses to the design procedures for bench configurations, inter-ramp slopes and overall slopes, including the analytical procedures commonly in use.
Conceptual Mine Design and Scheduling for the Riviera Project in Western Cape Feb 2009 DISCLAIMER AND RISKS This Conceptual Open Pit Mine Design and Scheduling Report have been prepared by Venmyn Rand (Pty) Ltd (Venmyn). In the preparation of the report, Venmyn has utilised information relating to operational
equipment, which may include a mining loader, shovel or excavator. Loaders lift the ore or waste material onto the trucks for removal from the mine. In an open-pit mine, loader types can include electric rope, hydraulic excavators including backhoe excavators, and front-end loaders (also called wheel loaders) (Er˘celebi and K rmanl, 2000).
shown that the most important factor in ultimate pit determination and in consequence in the whole planning and design procedure of an open pit mine is the metal price.

Open pit mine design is a significant portion of project management and we have attempted in this document to demonstrate where geotechnical engineering can be useful in improving mine design. Pit planning must be both economically sound and economically executed.
investment. On the contrary, opencast mining attracts environmental concerns such as solid-waste management, land degradation and socio-economical problems. In addition to that a large number of opencast mines, whether large or small, are now days reaching to deeper mining depths.
design for an open pit. Once this design element is complete it is usual then to evaluate both inter-ramp and overall slopes. The bench geometry is a function of both geotechnical conditions and mining systems, although in certain geotechnical conditions environmental factors will play a role. At

Mine optimization, design, planning and scheduling services are provided for open pit and underground mining methods using a range of commercial software packages. The configuration of mine access ramps, surface haulage routes and waste rock storage areas, and underground development layouts are based on operational experience.

They have an important influence on slope stability in the open pit, notably in terms of planar and wedge failures. Detailed geological and geotechnical data are often a notable unknown factor in the design and operation of an open pit, the lack of which may pose a significant risk to the mining venture.
