Coal is a principal source of energy and the combustion coal supplies around one-third global electricity generation. mines are also an important CH4 emissions, second most greenhouse gas. Monitoring emissions caused by mining using earth observation will require exact location mines. This paper aims to determine surface from satellite images through deep learning techniques treating them as la...

In surface mines, various activities (e.g., excavations, loading and unloading of material, moving vehicles on unpaved haul roads, etc.) represent significant sources fugitive dust. The estimation dust generation from each individual source is a basic step in planning implementation decision-making systems regarding the air quality surrounding area. Typically, this can be obtained by using emis...

Male, female, pupa, larva and egg of a new genus and species of Gracillariidae (Gracillariinae), Spinivalva gaucha Moreira and Vargas from southern Brazil are described and illustrated with the aid of optical and scanning electron microscopy. A preliminary analysis of mitochondrial DNA sequences including members of related lineages is also provided. The immature stages are associated with Pass...

A new perspective is presented for evaluating the slope stability of coal and lignite mines due to rainfall. The case Greek mining areas employed illustrate methodology. Initially, past climatic records rainfall are documented analyzed; intensity varies from light (0.8 mm/h) heavy (up 9 mm/h). Few extreme phenomena documented, with maximum being 17 mm/h. Furthermore, projections future trends p...

BACKGROUND In a community in northern Chile, explosive procedures are used by two local industrial mines (gold, copper). We hypothesized that the prevalence of asthma and rhinoconjunctivitis in the community may be associated with air pollution emissions generated by the mines. METHODS A cross-sectional study of 288 children (aged 6-15 years) was conducted in a community in northern Chile usi...

ational statistics on coal-mining productivity show that—except during the 1970s—coal mines have become steadily more efficient. More coal is removed per hour of work, causing a drop in both mining costs and coal prices. However, a new Energy Laboratory study suggests that those national statistics do not tell the whole story. When the researchers analyzed productivity data for more than ninete...

Navigation canals are used for transport purposes. In order to allow safe navigation the water level should be kept in a certain range around the Normal Navigation Level (NNL). The water level is disturbed by known and unknown inputs, like tributaries, municipal water flows, rain, etc. Some of these inputs can be used to control the water level. If the geometry requires it, canal reaches are co...
