Noise produced by blast waves can be a problem, especially when an explosion occurs near populated areas. As one means of reducing the blast noise, the explosive is detonated in a pit, a space closed at the bottom and sides, open at the top. A two-dimentional finite difference model was used to simulate such an explosion in a pit and to determine to what extent the blast wave was attenuated. Th...

The basis of emission assessment at the Open Pit "Milojević Brdo" is to define dust distribution depending on wind influence and emitters. This paper presents data for equipment engaged open pit. Through an analytical approach, total emitted by mining aeolian erosion in area pit was determined. results this analysis represent a prediction state impact environment during exploitation process

In an Open-Pit Production Scheduling (OPPS) problem, the goal is to determine the mining sequence of an orebody as a block model. In this article, linear programing formulation is used to aim this goal. OPPS problem is known as an NP-hard problem, so an exact mathematical model cannot be applied to solve in the real state. Genetic Algorithm (GA) is a well-known member of evolutionary algorithms...

A vehicle proximity warning collision avoidance system is being developed using GPS and wireless local area networks to improve safety of off-highway trucks in open pit mines. After two an a half years of research, software development, and laboratory testing, field tests were carried out at operating limestone quarries and open pit mining operations to evaluate GPS accuracy and overall system ...

Among the anthropogenic topographic signatures on Earth, open-pit mines are of great importance. Mining is of interest to geomorphologists and environmental researchers because of its implication in geomorphic hazards and processes. In addition, open-pit mines and quarries are considered the most dangerous industrial sector, with injuries and accidents occurring in numerous countries. Their fas...

During the last few years, most production-based businesses have been under enormous pressure to improve their top-line growth and bottom-line savings. As a result, many companies are turning to systems and technologies that can help optimise their supply chain activities. In this paper, we discuss a real-world application of scheduling in the mining industry. This is a highly constrained probl...

This paper presents an approach towards computationally efficient discrete-event-simulation designed to take advantage of high-performance computing architecture. We demonstrate how computational efficiency combined with large capacity enables quantification and mapping stochastic system performance across a challenging multidimensional parameter space requiring several million individual DES i...

This work tackles the open pit planning problem in an optimal control framework. We study optimality conditions for so-called continuous formulation using Pontryagin’s Maximum Principle, and introduce a new, semi-continuous that can handle optimization of two-dimensional mine profile. Numerical simulations are provided several test cases, including global one-dimensional final pit, first result...
