An Information System for a Bauxite Mine

An Information System for a Bauxite Mine

Bauxite is mined and transported by conveyor to a processing plant, screened and washed, then placed into blended stockpiles to feed the alumina refinery. While being stacked to the stockpile, the ore is sampled. Completed stockpiles must be acceptably close to target grade (composition), not only in alumina, but also in residual silica, carbon and sodium carbonate. The mine is an open-cut pit....

Growing Eremanthus erythropappus in crushed laterite: A promising alternative to topsoil for bauxite-mine revegetation.

Topsoil is the preferred substrate for areas requiring rehabilitation after bauxite mining. However, topsoil is sometimes lacking and so there is a need to test the suitability of other, locally available substrates. In an abandoned bauxite mine in Southeastern Brazil, small patches of native vegetation spontaneously established in shallow depressions over weathered laterite, suggesting that gr...

Mine, mine, mine: information theory, infostation networks, and resource sharing

The Infostations wireless data network architecture features discontinuous coverage and ultra-high radio rates for burst transfers of information between base and mobile. It has been shown previously that the infostations architecture can greatly increase the capacity of wireless data systems at the expense of increased delivery delay. In this work we explicitly consider the multiple access iss...

Object Construction by Deduction for a 3 D - Geo - Information System of a Mine

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 ...
