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).
The objective of this study is to develop and apply the new methodology of multi-criteria selection of open pit rock mining equipment based on multiple criteria decision-making (MCDM) procedures ...
The cost of open-pit mining is mainly composed of the loss of mining equipment and fuel consumption. Therefore, the choice of mining equipment will play a dominant role in the process and cost of open-pit mining. This article will share how to choose open-pit mining equipment reasonably.
Equipment selection in mining engineering is one of the most important decisions that affects the mine design, production planning and economic parameters in open pit and underground mining.
A new method of multi criteria decision making (MCDM) is proposed that makes it possible to select the optimal equipment that satisfies the decision maker and shows significant …
Open Pit Equipment Selection and Maintenance. Principal factors influencing equipment selection can be grouped into five basic categories. Tonnage …
INTRODUCTION Equipment selection in open pit mining is one of the most topical problems in theory and practice at present. The problem has provoked serious discussions in the world mining society. The philosophical point of the discussions is "whether the size of haul trucks and excavators has reached a feasibility threshold where the ...
By using relevant data, studies, and methods, mine planners at Atlantech assist miners to identify the most cost-effective opportunities to maximise productivity and equipment life at open pit mining operations. We are skilled at equipment selection, drawing on modern approaches. Please get in touch with us today if we can be of …
1 Introduction. The excavability or diggability of rocks in open pit mines has a major importance on selecting of excavation equipment. The right equipment selection by taking into account site specific conditions is the most important phenomena affecting the productivity in surface mining operations.
When it comes to final pit selection there is usually more than one option to choose from. Most deposits support a range of pit sizes that all are technically mineable and economically profitable. The size of final pit greatly affects other aspects of project such as life of mine, capital requirement, scale of operation, equipment size ...
Equipment selection is one of the most important aspects of open pit design. Mining costs are mainly affected by the number and capacity of equipment. Equipment selection for open-pit mines is definitely a major decision which will impact greatly the economic viability of an operation (Aghajani et al. 2007). Equipment selection effects economic …
Since equipment selection in an open-pit mine influences all stages of mining [10], the indiscriminate selection of larger equipment may not always be advantageous, especially in haulage equipment ...
In this paper the main issues related to the overburden management for large open pit mining operations have been discussed, describing the need of a multidisciplinary approach and of a focused laboratory and on-site test programme. ... The characterization of the materials is essential for equipment selection, and it is to be carried out in ...

Open pit mining method is one of the surface mining methods that has a traditional cone-shaped excavation and is usually employed to exploit a near-surface, nonselective and low-grade zones deposits. It often results in high productivity and requires large capital investments, low operating costs, and good safety conditions. The main …
