Implementation of Hyperbolic Tangent Function to Estimate Size Distribution of Rock Fragmentation by Blasting in Open Pit Mines
Rock fragmentation is one of the desired results of rock blasting. So, controlling and predicting it, has direct effects on operational costs of mining. There are different ways that could be used to predict the size distribution of fragmented rocks. Mathematical relations have been widely used in these predictions. From among three proposed mathematical relations, one was selected in this stud...
متن کاملDetermination of the largest pit with the non-negative net profit in the open pit mines
The determination of the Ultimate Pit Limit (UPL) is the first step in the open pit mine planning process. In this stage that parts of the mineral deposit that are economic to mine are determined. There are several mathematical, heuristic and meta-heuristic algorithms to determine UPL. The optimization criterion in these algorithms is maximization of the total profit whilst satisfying...
متن کاملAn Approach to Locate an in Pit Crusher in Open Pit Mines
Transportation costs are a significant part of capital and operating costs of large open pit mines. Cost efficiency and high reliability of in pit crushing and conveying systems compared to conventional truck-shovel system makes it more appealing to be utilized in modern mining activities. In this paper the suitable location of an in pit crusher is investigated as a single hub location problem....
متن کاملDevelopment 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...
متن کاملUtci for Assessing Heat Stress in Open-pit Mines
The purpose of this article is to examine the applicability of Universal Thermal Climate Index (UTCI) index as an innovative index for evaluating of occupational heat stress in outdoor environments. 175 workers of 12 open-pit mines in Tehran, Iran were selected for this research study. First, the environmental variables such as air temperature, wet-bulb temperature, globe temperature, relative ...
