Structure of energy consumption and improving open-pit dump truck efficiency

Development of a goal programming model for optimization of truck allocation in open pit mines

Truck and shovel operations comprise approximately 60% of the total operating costs in open pit mines. In order to increase productivity and reduce the cost of mining operations, it is essential to manage the equipment used with high efficiency. In this work, the chance-constrained goal programing (CCGP) model presented by Michalakopoulos and Panagiotou is developed to determine an optimal truc...

economic optimization and energy consumption in tray dryers

دراین پروژه به بررسی مدل سازی خشک کردن مواد غذایی با استفاده از هوای خشک در خشک کن آزمایشگاهی نوع سینی دار پرداخته شده است. برای آنالیز انتقال رطوبت در طی خشک شدن به طریق جابجایی، یک مدل لایه نازک برای انتقال رطوبت، مبتنی بر معادله نفوذ فیک در نظر گفته شده است که شامل انتقال همزمان جرم و انرژی بین فاز جامد و گاز می باشد. پروفایل دما و رطوبت برای سه نوع ماده غذایی شامل سیب زمینی، سیب و موز در طی...

Optimization of Design Parameters and Intelligent Back-analysis of High Bench Dump Slope in Open Pit

Dump engineering is an important part in production processes of open-pit mining. In order to complete the mine production tasks smoothly, it is necessary to make the most of land possessed by the dump in an economical and reasonable way. In the paper, we use the dump of Qidashan iron mine which belongs to Anshan Iron and Steel Group as an engineering background to achieve the aim of improving ...

Feedback Linearization Control for Path Tracking of Articulated Dump Truck

The articulated dump truck is a widespread transport vehicle for narrow rough terrain environment. To achieve the autonomous driving in the underground tunnel, this article proposes a path following strategy -for articulated vehicle based on feedback linearization algorithm. First of all, the kinematic model of articulated vehicle, which reflects the relationship between the structure parameter...
