Environmental contaminations resulting from mining operations play an important role in the collapse of ecosystems balance. In order to measure vegetation characteristics and to study soil and plant contamination in rangelands surrounding bauxite mine, a systematic random sampling was done according to physiognomy and homogeneity of vegetation cover. Sampling was performed using a 50-meter tran...

Gracilimonas tropica Choi et al. 2009 is a member of order Sphingobacteriales, class Sphingobacteriia. Three species of the genus Gracilimonas have been isolated from marine seawater or a salt mine and showed extremely halotolerant and mesophilic features, although close relatives are extremely halophilic or thermophilic. The type strain of the type species of Gracilimonas, G. tropica DSM19535(...

We have analyzed a frondelite mineral sample from the Cigana mine, located in the municipality of Conselheiro Pena, a well-known pegmatite in Brazil. In the Cigana pegmatite, secondary phosphates, namely eosphorite, fairfieldite, fluorapatite, frondelite, gormanite, hureaulite, lithiophilite, reddingite and vivianite are common minerals in miarolitic cavities and in massive blocks after triphyl...

In order to assess the ecological effect of acid mine drainage, metal mine (Dalsung) and coal mine (Samtan) drainage in South Korea were collected. The each mine drainage then investigated by whole effluent toxicity test (WET) and toxicity identification evaluation (TIE). WET results demonstrated that DS leachate and ST mine water is more toxic than other mine drainage due to the presence of ca...

Relevant implementation of the EU Water Framework Directive with regard to mine water pollution of downstream water bodies requires pressure-impact assessment and catchment-scale economic optimisation of abatement measures. However, pressure-impact assessment is bound to be uncertain. This is because mine water pollution is often an unknown combination of pollution loads, from both known mine w...

The Norwegian long-term program for military use of autonomous underwater vehicles (AUVs) reached an important milestone in December 2001, when the concept of AUV based mine hunting and rapid environmental assessment (REA) was demonstrated from the Oksøy class mine hunting vessel KNM Karmøy. Within one day, the complete concept of AUV based mine hunting was demonstrated: The HUGIN AUV was progr...

Amending contaminated soils with organic wastes can influence trace element mobility and toxicity. Soluble concentrations of metals and arsenic were measured in pore water and aqueous soil extracts following the amendment of a heavily contaminated mine soil with compost and biochar (10% v:v) in a pot experiment. Speciation modelling and toxicity assays (Vibrio fischeri luminescence inhibition a...

A Pb-mine site situated on acidic soil, but comprising of Ca-enriched islands around derelict buildings was used to study the spatial pattern of genetic diversity in Lumbricus rubellus. Two distinct genetic lineages ('A' and 'B'), differentiated at both the mitochondrial (mtDNA COII) and nuclear level (AFLPs) were revealed with a mean inter-lineage mtDNA sequence divergence of approximately 13%...

In this paper, by analyzing the coal mine safety accident of present stage, the author has come to a conclusion that the safe accidents on coalface accounting for a lot of coal mine safety accident, and has brought forward the cause leading to this phenomenon. Then, through the discussion about “Overlying Strata Movement Law”, this author has suggested that Electronic Business can be used for t...

The two primary measures of land mine detection performance are the probability of detection Pd and the probability of false alarm Pfa.These two measures are highly interdependent and must be evaluated together. The relationship between the two probabilities directly a ects the overall performance of the sensor in the eld. In this paper we introduce a novel false alarm non-parametric lter based...
