metallurgical models, and mining models; can be reconciled to treatment plant feed tonnes, grade and actual mineral product produced. Sample Collection and Compositing The selection of drilling sample intervals and compositing strategies are typically planned very early in the exploration phase of projects.


CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): many industries, materials handling represents a significant component of the operational cost, making equipment selection an important challenge to management. To meet this challenge, extensive research has taken place in the mining and construction industries which are heavily dependant on equipment.

Mining Equipment specializes in rail mounted equipment. We have a very large inventory of diesel, battery and trolley locomotives in stock. Various models by Plymouth, Clayton, Brookville, Schöma, Goodman, Greensburg and General Electric can be offered. In addition to locomotives, we also have a large inventory of rolling stock such as muck ...


One of the challenging problems for surface mining operation optimization is choosing the optimal truck and loader fleet. We refer to this problem as the equipment selection problem (ESP). In this paper, we describe the ESP in the context of surface mining and discuss related problems and applications.


For the mining industry, this ratio is an important performance indicator with a dual purpose: during the equipment selection phase, it can be used …


mining equipments selection. This system is able to involve the expert knowledge in primary and secondary selection of equipment for surface coal mines [3]. In 1990, another expert system, in order to classify equipment, was planned in the open pit coal mine of Britain with the help of fuzzy logic.
