Comparative study of algorithms for mining association rules: Traditional approach versus multi-relational approach
(2011-12-01)
The multi-relational Data Mining approach has emerged as alternative to the analysis of structured data, such as relational databases. Unlike traditional algorithms, the multi-relational proposals allow mining directly ...
Optimum ramp design in open pit mines
(Elsevier, 2020)
The problem studied in this paper is that of designing the optimal open pit haulage ramp that, for a given ramp width and a maximum ramp gradient, connects two points of the mine, minimising construction and operational ...
MR-Radix: a multi-relational data mining algorithm
(2012)
Background: Once multi-relational approach has emerged as an alternative for analyzing structured data such as relational databases, since they allow applying data mining in multiple tables directly, thus avoiding expensive ...
Mining the Media: How Community Radio Breaks Through Extractivist Discourse Articulations in a Context of Disaster and Socio-environmental Conflicts
(Routledge Journals, 2020)
Mining extractive companies have extended their operations to other realms, such as the management of media. Thus, from a space of physical intervention, they start to conquer a space of symbolic representation, creating ...
Mercury dispersal to arroyo and coastal sediments from abandoned copper mine operations, El Boléo, Baja California
(Bulletin of Environmental Contamination and Toxicology, 2009)
Evidence for mercury dispersal in an arid coastal region of central Baja California (Mexico) suggests that abandoned copper mining operations are a noticeable source of mercury in the environment. There is a generally ...
High Power Cycloconverter for Mining Applications: Practical Recommendations for Operation, Protection and Compensation
(2015)
This paper presents practical aspects related with the operation, compensation and protection of high power cycloconverters used in mining industry. Practical recommendations related with start-up, operation characteristics ...
The socio-political dynamics of transnational mining in Argentina: The cases of Puerto San Julián and Esquel in Patagonia
(Elsevier, 2016-11)
The purpose of this article is to analyze and compare the socio-political dynamics of two different mining projects in Patagonia, Argentina. In Puerto San Julián, AngloGold Ashanti (AGA) and the provincial mining development ...
Modelagem de dados de entrada para simulação estocástica de lavra
(Escola de Minas, 2010)
A simulação de lavra depende da utilização de dados coerentes e representativos da operação da mina. Esse trabalho propõe uma metodologia de modelagem de dados especificamente desenvolvida para simulação de lavra. A ...
Rapid assessment of environmental health risks posed by mining operations in low- and middle-income countries: Selected case studies
(Springer, 2013)
Previous studies have evaluated associated health risks and human exposure pathways at mining sites. Others have provided estimates of the scale of the issue based in part on surveys. However, a global census of mining-related ...
