Recently, many Natural Language Processing (NLP) applications have improved the quality of their output by using various machine learning techniques to mine Information Extraction (IE) patterns for capturing information from the input text. Currently, to mine IE patterns one should know in advance the type of the information that should be captured by these patterns. In this work we propose a n...

nitrogen oxides and carbon monoxide gases together with dust are known as the major pollutants arising during the blasting operations using the ammonium nitrate-fuel oil (anfo) explosive at the sungun surface mine, located in the northwest of iran. the pollutants were monitored during some blasting operations at the mine. it was concluded that the gases and dust clouds initially went up to the ...

KiG No. 26, Vol. 1 5, 201 6 88 melted in Rude, in a blast furnace with an annual capacity of 25,000 cents, one part ofwhich was transported to Slovenia. Annual production of iron ore was between 20,000 and 130,000 cents, while annual production ofiron was between 5,000 and 16,000 cents. The mine was closed in 1859 due to unprofitability. Twenty-six thousand tons ofore were extracted during the ...

Outburst closed distance coal seam distances are extremely difficult to mine, and commonly involved in safety accidents the process of mining. Based on engineering background Wulan Coal Mine at western margin Ordos Basin, this paper presents a theoretical analysis, analogies, numerical simulations determine optimal mining sequence for #7, #8, #2, #3 seams. Floor penetration drilling was used el...

Shifting markets can cause unexpected, stochastic changes in rural landscapes that may take local communities by surprise. Preferential siting of new industrial facilities in poor areas or in areas with few regulatory restrictions can have implications for environmental sustainability, human health, and social justice. This study focuses on frac sand mining-the mining of high-quality silica san...

Mining companies have become increasingly aware of the potential of microbiological approaches for recovering base and precious metals from low-grade ores, and for remediating acidic, metal-rich wastewaters that drain from both operating and abandoned mine sites. Biological systems offer a number of environmental and (sometimes) economical advantages over conventional approaches, such as pyrome...

an ex-situ experiment to assess the metal extractive potential of fourteen agriculture plants (vigna unguiculata, gossypium hirsutum, jatropha curcas, etc.) was conducted on magnesite mines which had above permissible levels of cadmium and lead. there was no much difference in the total chlorophyll a and b, carbohydrate and protein contents in the plants grown in the mining soil and adjacent co...
