Numerically speaking, the stochastic mine planning model improves 6% expected cumulative discounted cash flow and generates 16% more iron ore than deterministic model.

The Rail Scheduling Tool (RST) is a tool to facilitate the planning and scheduling of train operations which was developed by Optym Private Limited to provide solutions for the BHP Billiton Iron Ore supply chain. …

Stochastic optimisation provides a framework that is capable of generating a strategic life-of-mine production schedule that increases net present value while simultaneously reducing the risk associated with geological uncertainty. This paper focuses on the application of the stochastic strategic mine planning for technical risk …

Medium-Term Rail Scheduling for an Iron Ore Mining Company. This paper presents an optimization tool developed for a major multinational iron ore mining company to manage the operations of its supply network in the Pilbara region of Western Australia that allows the company to ship a higher amount of iron ore. Expand.

When you begin planning and drafting your project schedule, you want to include all project activities. At first, the project management scheduling process may feel a bit foreign to you—that's normal!

XECUTE maximises planning value, adaptability and agility by using automation to connect planning with operations, providing cross-team collaboration and integrated design and scheduling.

A new scheduling model for the bulk ore blending process in iron-making industry is presented, by converting the process into an assembly flow shop scheduling problem with sequence-depended setup time and limited intermediate buffer, and it facilitates the scheduling optimization for this process. To find out the optimal solution …

In underground mine planning, production scheduling is the sequencing of mining activities, i.e., development, production, and remediation, needed to achieve clearly defined goals in order to ...

The results show the capacity of the stochastic mine planning model to identify and minimize risks, obtaining valuable information in ore content or quality at early stages of the project, and improving decision-making with respect to the deterministic production scheduling.

Regarding this circumstances, Antam has figure out the mineral reserve Keywords: ore blending, mine scheduling, resources conservation, strategic planning 1. INTRODUCTION Antam is a vertically integrated, export-oriented, diversified mining and metals company.

Thus, this article aims to explore this subject, proposing an energy scheduling algorithm to optimize the electricity consumption of a large iron ore stockyard-port terminal considering multiple power suppliers and batteries.

Short-term scheduling in open-pit mines has multiple hierarchical objectives to optimize. This work proposes an optimization methodology to generate a short-term open-pit mine production schedule ...

This paper studies the production and distribution planning problem faced by the iron ore mining companies, which aims to minimize the total costs for the whole production and distribution system of the iron ore concentrate.

Iron ore quality depends upon successive shipments being uniform in composition, not only in iron but also in several other minerals. The production process involves several stages of scheduling ...

The proposed algorithm is based on the ore handling operations in a real stockyard–port terminal, considering the interaction of large physical equipment and information about the production processes.

Create new Pacesetter maintenance planning and scheduling performance like that in the table below in your operation. Learn the best practices and methods, the specific requirements and the systems that need to be in place (and in use) to get the most from planning and scheduling.

Additionally, compliance with grade quality depends on blending minerals from different sources. In this paper, we present an optimization tool developed for a major multinational iron ore mining company to manage the operations of its supply network in the Pilbara region of Western Australia.

This paper introduces a vessel voyage schedule planning problem for maritime ore transportation arising from a real-world project in Boffa, Guinea. In this problem, delay of vessel arrivals at the loading port often occurs which interrupts the ore loading operation and further impacts the yearly throughput of ore transportation, which …

This variability is an important factor in the prediction of ore grades in the geological model, and therefore also in the mine planning, production scheduling, and grade control.

Reconciliation at large iron ore operations is a complex and time-consuming process. Often the volume of data and the large range of different stakeholders makes the process almost impossible.

We find that domestic firms in China's iron ore mining industry that conduct R&D are on average 0.3937% more productive and their sales are 0.0253% higher. While this industry attracts less than 1% of the total FDI in China, FDI has a positive and sizable impact on both productivity and profitability of domestic firms in China's iron ore ...

Open pit optimization, stochastic simulation, Multi-element deposits, Iron ore INTRODUCTION Long-term mine planning and production scheduling aim to define the "best" mine plan subject to the constraints imposed by physical and geological conditions, policies and the operational mining approach.

Due to the importance of defining the energetic planning and scheduling of activities for an iron ore stockyard–port system including various types of ore with different characteristics, this paper presented an MILP model adapted to the energy sector and an LRBH to solve this problem.

The optimisation tools for open pit strategic planning, in Proceedings Iron Ore 2013, pp 215-220 (The Australasian Institute of Mining and Metallurgy: Melbourne). Optimisation tools for open pit mines such as the scheduling and pit optimisation tools have become cost-effective ways to evaluate open pit mine project as well as improving mine ...

This work proposes a new mixed integer linear programming (MILP) model for stockyard planning solved by a linear relaxation-based heuristic (LRBH) to minimize the plan's energy cost. Planning the use of electrical energy in a bulk stockyard is a strategic issue due to its impact on efficiency and responsiveness of these systems. Empirical …

Iron ore production increased 6% y/y driven by a record output for a second quarter at S11D, followed by solid performance at Itabira and Vargem Grande complexes, improving Vale's average product portfolio quality. Pellet production increased 5% y/y driven by the higher production at Tubarão plants as a result of higher pellet feed production.
