Equipment selection for high selective T excavation

In open pit mining, equipment selection is made according to many factors related to the ore and mining conditions. These factors can be qualitative and quantitative in nature. The main purpose of equipment selection is to choose the optimum and cost-effective equipment by installing a decision-support system, which can analyse various and complex factors. The term optimum here reflects that

Surface Mining Methods and Equipment

underground mining equipment is specialized and expensive. A number of surface mines operate 24 hours/da y and almost 365 days/year in order to use open pit machinery for as many hours as possible, thereby reducing the number of machines required. In contrast, underground operations are often interrupted by the need for maintenance in addition to non-productive hours required for commuting

Models for Mining Equipment Selection

objectives for an equipment selection model. A new Mixed Integer Linear Programming model is presented that makes use of a linear approximation of the cost function. This model allows for mixed- type fleets and selects the truck and loader types within the solution. The results demonstrate that heterogeneous fleets can result in savings for the mining operation. Problems arising from IP

ESTABLISHING TOTAL AIRFLOW REQUIREMENTS FOR UNDERGR

(particularly in the case of new mine design) and should be performed while carefully considering how the equipment fleet required will be influenced by all of the relevant design parameters. Only once the selection of the necessary equipment is made can the process of determining the total amount of airflow required be completed. Figure 1 shows a graphical representation of the relationship

14 aspects to consider in equipment selection Consulting

18/04/2016· Conversely, equipment selection for a mechanical engineer is as much an art of application as a science of technology. Today, refinements to manufacturing, increasingly advanced controls, and changing end-user needs determine both the science of technology and the roster of equipment for selection.
