The aim was to design a MATLAB program calculate the phreatic surface of multi-well system and present graphical shape water table drawdown induced by extraction. Dupuit’s assumption is base for representing dewatering curve. will offer volume be extracted, total number wells, spacing between them as well expected settlement soil surrounding foundation pit. arrangement required in execution wor...

A daunting mine disaster took place in 13 May 2014 at Soma and 301 men lost their lives. Brief information about the Eynez coal mine and some of the inherent characteristics of the field in terms of their effects on mining are presented. This paper basically concentrates on the factors that played an important role in the occurrence of this disaster. Progress of mine fire, firefighting, and res...

A concentrate treatment process is needed to improve the quality of concentrate. Processing copper minerals by drying or dewatering. The slurry dewatering intended inhibit rate damage concentrate, and it easy distribute through shipping. PT. Freeport Indonesia has 2 types machines for process, Rotary Dryer VPA (Vertical Pressure Airblow). dryer dries evaporating water in a combustion with tempe...

Abstract Sludge is one of the by-products wastewater treatment plants (WWTPs). To assist biological processes, part produced sludge returned to process and excess removed from plant whereby it undergoes thickening dewatering. Numerous studies have been conducted investigate effect different coagulants on dewatering sludge, but using divalent iron for this purpose has not investigated so far. In...

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 ...

sludge drying bed is preferred to mechanical methods due to the need for very simple technology. due to restriction of natural dewatering, we tried to eliminate some of these limitations by the tests and studies of assumptions. in this study, the effect of hydrostatic suction and sludge chemical conditioning has been studied in the natural sludge dewatering optimization. at first, hydrostatic s...

conventional processes of food dewatering, such as thermal, have undesirable and destruction effects on vitamins, aromatic compounds and pigments. in addition, they are accompanied with some technological complications and energy consumption. thus, food concentration processes are directed to non-thermal techniques or methods with reduced heat effects. superabsorbents are highly hydrophilic pol...

Doing large-scale genomics experiments can be expensive, and so experimenters want to get the most information out of each experiment. To this end the Maximally Informative Next Experiment (MINE) criterion for experimental design was developed. Here we explore this idea in a simplified context, the linear model. Four variations of the MINE method for the linear model were created: MINE-like, MI...

the present study represents a first insight into the draa lasfar min (marrakech - morocco) to assess the degree of polymetallic pollution caused by anthropogenic activities (like mine extraction) and consequently the possible diffusion of heavy metals and to predict the risk of their mobility in the surroundings of the mine area. the edaphologic parameters ph and electrical conductivity (ec) w...

Sponsored by Defense Threat Reduction Agency Contract DSWA01-98-C-0176 The Mine The cooperating mine was the Morenci Mine operated by Phelps-Dodge in SE Arizona. The scale of the operation is illustrated below. The mine produces over 25% of all US copper. Three to five blasts are detonated daily. During July and August, 31% of the events in the USGS Mine Event List were from this mine. Regional...
