In this study, we studied the drying process, grinding characteristics and physicochemical characteristics of broccoli sprouts (BS). The seeds of broccoli were germinated at 20 °C for 3 and 6 days. Then, the seeds were air- and freeze-dried, and the Page model was used for prediction of drying kinetics of broccoli sprouts. It was observed that the drying time of BS decreased about twofold as ...

underground mining is cost effective and practiced. •Dips have got an effect on the unit mining cost, mining method, UPD achieved, Mining depth and productivity. SEAM DIP •Seams 1-4 in different areas suffer from seam continuity as a result of seam blanking, faulting and replacement. •The seam mostly affected by seam low continuity is seam 1.
This paper, firstly, characterizes the mining waste of the Betare-Oya gold area (East Cameroon). Surface waters are sampled and characterized physically (pH, electrical conductivity, turbidity, and suspended solids) and chemically by the determination of trace metals (Cu, Zn, Ni, Mn, Fe, Cr, As, and Pb). The concentrations of heavy metals in sediment samples are determined by X-ray ...
The mining operations feature ... regionally and nationally on the effects of mining on water quality, the majority of these studies investigated water quality using physicochemical variable without use of bioindicators. This study seeks to investigate the effects of both conventional and small scale gold mining ...

The paper discusses the imperatives of sand mining and the environmental. impacts using selected case histories in the Niger Delta and elsewhere. The. continuation of sand mining in spite of the associated adverse environmental. effects, have been linked to the creation of new usable land from marginal.
Seepage from a tailings dam associated with a copper mine located in Ganzhou, Jiangxi Province, China, may affect surrounding groundwater quality during mine operations. A groundwater environmental impact assessment (EIA) is an important aspect of China's current EIA system, and is used to protect groundwater quality.

The drinking water quality was investigated in suspected parts of Perak state, Malaysia, to ensure the continuous supply of clean and safe drinking water for the public health protection. In this regard, a detailed physical and chemical analysis of drinking water samples was carried out in different residential and commercial areas of the state. A number of parameters such as pH, turbidity ...
Define Mining Operations. includes: To this end, Victoria will ensure that in accordance with relevant Victorian legislation proposed Mining Operations in the CAR reserve system will be subject to an Environmental Effects Statement or planning permission (e.g. planning permit) as required.. Currently identified core program focus areas are:• Stormwater permitting and compliance ...

health screening practices in the coal mining industry on a global scale. In light of these deficiencies failing to protect the health of coal workers, there is an immediate need to investigate the differential effects of different particulate matter (PM) exposures arising from different mining operations on respiratory health.
Mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself. The effects of this damage can continue years after a mine has shut down, including the addition to greenhouse gasses, death of flora and fauna, and erosion of land and habitat.
The impact of poisonous gases generated during blasting operations on the health of workers depends on the concentration of this gas, the numerical value of which depends on the explosive used and the oxygen balance of the mixture, as well as the blasting conditions and rock properties.
