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...

Mapping the regulatory frameworks for mine closure planning around Australia requires consideration of several overlapping and enmeshed legal concepts, institutions, powers processes. It can encompass environmental, economic, social, cultural climate transitions site surrounding region. Mining create complex and, in some cases, irreversible impacts, which must be considered pre-emptively to opt...

A three-dimensional Geo-Information System (GIS) for planning and operating a mine is described. On a conceptual level, the underlying database is speciied using the notation of Rumbaugh's Object Modeling Technique (OMT). The paper focuses on the problems caused by the implementation of such an Object Oriented Data Model by at relations as provided by a standard RDBMS. A running implementation ...

The typical problems caused by Mining Subsidence and mining pollution made by coaling, made the Mine Subsidence reclamation and retorting the integrated mining environment necessary. Then, we create effective management measures of “full investigation, scientific planning, focused, sound institutions, the establishment of the system” and create the advanced technology of “mud pump reclamation, ...

Mine planning models have proved to be very effective in supporting decisions on sequencing the extraction of material in copper mines. These models have been developed for CODELCO, the Chilean state copper mine and used successfully. Here, we wish to develop a corporate model, including all mines of CODELCO. The original models are extremely large MIPs. In order to run a global model, the orig...

Planning and design procedure of an open pit mining project just can be started after ultimate pit determination. In the carried out study in this paper it was shown that the most important factor in ultimate pit determination and in consequence in the whole planning and design procedure of an open pit mine is the metal price. Metal price fluctuations in recent years were exaggerated and impose...
