Coal slurry is an essential component of mining operations, accounting for more than half operating costs. Dewatering technology simultaneously confronted with obstacles and possibilities, it may yet be improved as the crucial step reducing ultimate processing cost. Coagulation/flocculation used a dewatering process that reasonably cost-effective user-friendly. This paper reviews application di...

Ensuring effective sealing of casing columns in boreholes requires the use appropriate technology cement slurry injection into annular space and a properly designed recipe. Very often, when selecting technological parameters slurry, special attention is paid to fresh but little mechanical sheath that being formed (the after setting). In order improve hardened space, new generation with increase...

The speciation and partitioning of mercury from two Spanish pulverized coal (co) combustion (PCC) power plants equipped with wet limestone-based flue gas desulphurization facilities (FGD) have been evaluated in this work. The results were obtained by simultaneously sampling the solid, liquid and gaseous streams in the power plants and by determining the mercury content in the representative sam...

The effectiveness of chemical amendment of pig slurry to ameliorate phosphorus (P) losses in runoff is well studied, but research mainly has concentrated only on the runoff pathway. The aims of this study were to investigate changes to leachate nutrient losses, soil properties and greenhouse gas (GHG) emissions due to the chemical amendment of pig slurry spread at 19 kg total phosphorus (TP), 9...

There has been an ongoing research on coal and gas outburst for the past two decades at the School of Civil, Mining and Environmental Engineering, University of Wollongong. Research study began with a humble beginning, initially conducting basic laboratory studies on the coal and gas properties, progressing into the determination of gas content of coal by sorption technique and the effect of ga...

the design of cement slurry for horizontal wellbores is challenging as it must present very high quality cement slurry properties e.g. zero free water, less than 50 cc api fluid loss value, appropriate rheology and yield point for effective displacement, adequate compressive strength, which is critical for lightweight slurries, and finally stable cement column behind casing. the main objective ...

Plasma glucose levels provide the cornerstone of diabetes evaluation. Unfortunately, glucose levels drop in vitro due to glycolysis. Guidelines provide suitable conditions which minimize glycolysis, such as immediate centrifugation or the use of ice/water slurry storage containers. For obvious practical reasons, most laboratories use blood collection tubes containing glycolysis inhibitors. We d...

Surface coal mining has become the ideal method for extracting coal from the Appalachia Mountains. However, surface coal mining generates large amounts of waste which may decrease the water quality in central Appalachia. This research is an attempt to determine whether surface coal mining negatively impacts water quality. This research consists of a literature review in addition to an analysis ...
