Holeworks: algoritmo de geração de tabela de entrada de dados no SGEMS

Abstract

In this work we've been involved with the use of geostatistical processing software, specifically SGeMS and the data it should use. Our goal was to use data from a database belonging to a real company using the software SGeMS and generate a model of the ore body kriged by this software. In this case the data is owned by Sierra Sossego Mining company Vale SA However, the company's data could not be directly used by the software we had and to do so would require a reordering of these to make them compatible. Hence the justification for this work, the development of an algorithm capable of importing data from the company and sue them and export them to be used by SGeMS in a kriging model. The reason for the creation of an algorithm is the volume of data involved in a database from a mining company, which can hold data in the order of millions of records, which prevents the treatment manual. The other reason is how the data are in the database the company uses to polar coordinates, but in SGeMS uses to Cartesian coordinates. The result of this work was the development of proprietary software capable of such tasks to import and process the data to then generate a file compatible with SGeMS doing it so fast and almost unattended, this software was named according to their HOLEWORKS purpose.
