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...

Underground mining under an open-pit slope results in movement and instability of rock masses. However, most mass prediction methodologies are empirical only suitable for underground mining. In this paper, a new theoretical methodology is proposed to predict the masses caused by mining, combining two influences, slopes Considering influence open pit on damage patterns, double-slip surface defle...

Sustainability of the open pit mining and technical system (MTS) is one its key goals in changing conditions external internal environment. All MTS’s subsystems must function concert to achieve this goal. The structure MTS formed by many elements, which are evaluated a significant number indicators. A comprehensive assessment for all possible indicators complex time-consuming task. However, eac...

River bed sand and gravel are utilized more than mountain materials due to their availability and closeness to the transit roads and sites of usage. Excessive and non-technical extraction of gravel and sand bring a kind of interference in them, leading to many negative consequences. Therefore, presenting solutions to reduce these impacts and infilling mining pits are essential. In this researc...
