ABSTRACT: Selecting transport equipment is one of the most important and basic parts in the planning of every project, particularly mining projects due to holding a high charge of the total project's cost. So it can affect the fact that the project is economical or not. Criteria and a variety of parameters have an influence on the selection of equipment, while these criteria often are in confli...

Pelletizing plant of the Gol-E-Gohar mining and industrial company consists of a burner, a dry ball mill (6.2 m × 13 m), and an air separator. The ball mill consists of a 2 m-long drying and an 11 m-long grinding chambers. The iron ore concentrate is fed to the drying chamber by a feed chute. It was found that when the feed moisture content increased from 1.3% to 3.5%, the throughput decreased ...

optimization of the exploitation operation is one of the most important issues facing the mining engineers. since several technical and economic parameters depend on the cut-off grade, optimization of this parameter is of particular importance. the aim of this optimization is to maximize the net present value (npv). since the objective function of this problem is non-linear, three methods can b...

An increasing number of organizations are involved in the development of strategic information systems for effective linkages with their suppliers, customers, and other channel partners involved in transportation, distribution, warehousing and maintenance activities. An efficient inter-organizational inventory management system based on data mining techniques is a significant step in this direc...

Business and scientific organizations, nowadays, own databases containing confidential information that needs to be analyzed, through data mining techniques, in order to support their planning activities. The need for privacy is imposed due to, either legal restrictions (for medical and socio-economic databases), or the unwillingness of business organizations to share their data which are consi...

Industrial competence and real business cases can be great attributes to higher education curriculum. For engineering higher education, there is a need for these attributes, not only to enrich the curriculum, but also to reduce the gap between theories and practices. An innovative teaching approach is integrating these attributes into off campus industrial lectures conducted during company visi...

Economic benefit of an industrial company depends on forethought deployment of an industrial production system. Configuration of the robotic system affects the whole production process, and selection of inappropriate option can lead to financial losses of the company. The author proposes a formal procedure for finding an optimal specification of a heterogeneous multi-robot system. The paper pre...

there are more than 750 counties in 13 provinces and autonomous regionsconstituting 30% of china lands which are facing serious problem of desertification. theseareas are mainly distributed in arid, semi-arid and dry sub-humid areas in the western part ofnortheast china, north central china and most of northwest china. biological methods are theultimate way for drift sand stabilization and a fu...

During the production of aggregates at quarry sites, elevated quantities of micro-particulate mineral dust are produced in all stages of the process. This dust contains appreciable amounts of free crystalline silica in a variety of forms which, if maintained suspended in the air in the work environment, expose the workers to the risk of developing occupational silicosis, which causes reduced ab...
