The Economic-probabilistic Model for Mining Hydraulic Excavator the Exploitation Cost, Servicing and Optimal Lifetime Estimation

R.Y. Poderni, P. Bules

Comparative analysis of the most important technical and cost characteristic, as well as service life property of Hydraulic Mining Excavavors has been done in this paper. The process of a Hydraulic Excavator selection for modern high-production surface mining operation is really complex. A mine purchasing and operations groups must examine various types of excavation equipment and technical specifications to ensure that they choose the correct machines — machines that will provide not only the production quotas but also at the lowest cost per unit loaded. The high mobile Hydraulic Excavators are excellent machines for high-production, low-cost mining applications where reliability is the key to profitability. This model analysis provides a generalization of that equipment application expertise in an effort to simplify and enhance the Mining Hydraulic Excavator application. Your final and specific selection decision of the Excavator type must be based on the sum of your personal preferences and cost analysis, which can be done by means of this proposed economical model.
