poland is a traditional mining country ranking high in europian mining. a considerable part of polish national-gross-product comes from mineral resources. a large number of the working people work in the mines and related industry. research and educational centers depending on mining are well grown and are of great importance. the major mining commodities of poland are: coal, brown coal copper,...
| Incremental mining algorithms that can eeciently derive the current mining output by utilizing previous mining results are attractive to business organizations since data mining is typically a resource-intensive recurring activity. In this paper, we present the DELTA algorithm for the robust and eecient incremental mining of association rules on large market basket databases. DELTA guarantees...
Traditionally, data mining is an autonomous data-driven trial-and-error process. Its typical task is to let data tell a story disclosing hidden information regarding a business issue. Driven by this methodology, domain intelligence is not necessary in targeting the demonstration of an algorithm. As a result, very often knowledge discovered is not generally interesting to business needs. However...
for about a decade the virtual water trade has been highlighted as a means of promoting water efficiency and helping to solve regional restrictions of water resources in order to provide water and food security. although these tools are not just for certain areas of the world with a specific climate, they are more important for countries which are faced with water resources restriction and cris...
Acid mine drainage (AMD) is among the major environmental concerns related to mining activity and often causes complete degradation of affected ecosystems during and/or after closure [...]
We assessed the exposure of fish from the Spring and Neosho Rivers in northeast Oklahoma, USA, to lead, zinc, and cadmium from historical mining in the Tri-States Mining District (TSMD). Fish (n = 74) representing six species were collected in October 2001 from six sites on the Spring and Neosho Rivers influenced to differing degrees by mining. Additional samples were obtained from the Big Rive...
Incremental mining algorithms that can efficiently derive the current, mining output by ut,ilizing previous mining results are attractive to business organizations since data mining is typically a resource-intensive recurring activity. In this paper, we present the DELTA algorithm for the robust and efficient incremental mining of association rules on large market basket databases. DELTA guaran...
The first step in mining activities is rock excavation in both mine development and production. Constant pressure for cost reduction and creating an improved/safe work environment for personnel has naturally resulted in increased use of mechanical excavation systems in many mining operations. Also, mechanical excavation and mining is more compatible with automation, meaning possibility of reduc...
Introduction The mining industry is responsible for several detrimental effects on health and the environment through the mining process itself as well as through pollution. Although there is a wide range of health impacts associated with mining depending on the mineral and mining type, dust is common to all types of mine processes, and respiratory effects, especially for workers, are among the...
