ENHANCING SHRUB ESTABLISHMENT BY UTILIZING DIRECT HAUL TOPSOIL ON MINE SPOILS IN WESTERN COLORADO

Arsenic fractionation in mine spoils 10 years after aided phytostabilization.

Aided phytostabilization using a combination of compost, zerovalent iron grit and coal fly ash (CZA) amendments and revegetation effectively promoted the biological recovery of mining spoils generated at a gold mine in Portugal. Selective dissolution of spoil samples in combination with solid phase characterization using microbeam X-ray absorption near edge structure (μXANES) spectroscopy and m...

Biotic Interactions Influencing Shrub Establishment

BIOTIC INTERACTIONS INFLUENCING SHRUB ESTABLISHMENT ON AN ATLANTIC COAST BARRIER ISLAND. Elucidating mechanisms influencing the establishment of woody species is essential for understanding community dynamics and successional processes on barrier islands. The relative intensity of facilitation and inhibition of grasses on seedling establishment of two woody species common to Atlantic Coast barr...

Risk Assessment and Spatial Modeling of Heavy Metals Contamination in Topsoil around Venarj Manganese Mine by Artificial Neural Networks Method

Background and Objectives: The aim of the present study was to assess the probable heavy metals contamination in topsoil surrounding Venarj mine in Qom province using contamination indices and artificial neural networks method. Material and methods:  in order to evaluate the contamination status around Venarj mine in Qom province, 70 soil samples were collected in an area of 22 Km2, and  the to...

Estimation of reliability-based maintenance time intervals of Load-Haul-Dumper in an underground coal mine

Reliability estimation plays a significant role in the performance assessment of mining equipment, and aids in designing efficient and effective preventive maintenance strategies. Continuous and random/irregular occurrence of failures in a system could be the main cause for performance drop of machinery. The accomplishment of a projected level of production is possible only by an efficient oper...
