Abstract According to the gypsum mine goaf disaster formation mechanism and failure characteristics, wireless monitoring system of gypsum mine goaf was designed successfully by using virtual instrument technology, modern sensor technology, wireless transmission technology and the.
The Waldorf mine site in Clear Creek County, Colorado Fig. 1 was selected for a suite of integrated studies because the adit, or horizontal shaft that serves as a drain beneath the main mine workings, delivered a steady stream of mine water discharge across the waste dump.The flow from the adit was measured above and below the waste dump, allowing the rate of infiltration passing through the.
Where R Gypsum is the dissolution rate of gypsum, k 1 is the rate constant, A g is the surface area of gypsum, V is the liquid volume in contact with the gypsum surface, IAP is the product of ion activity, and K is the ion solubility product.
2018-5-10Surface water which is the most significant inland water resource for human consumption, agricultural activities, recreational and industrial purposes Razmkhah et al. 2010 has always been the end point of wastewater disposal from the adjacent areas.Lithology of river basins, anthropogenic inputs, climatic and atmospheric conditions affects the quality of surface water at any point.
2008-10-29Pelucchi area, the piezometric level is strictly related to atmospheric precipitation water level variations recorded a delay of less than 24 hours. Water sampling and chemical analysis were used to study the hydrochemical features of the mine water and multi-parameter log analysis allowed the.
Consisted of lignite or native, silty clay. The A1 Area Landfill groundwater monitoring wells are all completed within the spoil zone. 2.3 Groundwater Potentiometric Surface Elevations Eight background groundwater monitoring events were performed using the A1 Area Landfill CCR monitoring well system.
Summary and conclusions The behaviour of acidic mine drainage within unsaturated waste rock piles has been simulated using a multi-component pyrite oxidation and reactive transport model. The base case simulation results were consistent with observed data at the Doyon mine, with minimum simulated pH levels of 2.8 and maximum sulphate and ferrous iron concentrations of 100,000 mg L 1 and 1000.

2017-6-27Flue gas desulfurization gypsum FGD Gypsum is an industrial byproduct derived from the desulfurization of flue gas produced by the combustion of sulfur-containing fuels mainly coal and has been widely applied for improving agricultural soils and for the investigation and practice of mine reclamation Dick 2006 Chen 2011. Studies have.

Study area South west Punjab Imagery used IRS 1C satellite, LISS III Results During ground verification salt accumulation was also found to be associated with salt grass and salt tolerant wild vegetation. The area mapped in the classes of moderate.
Data-driven, multi-model workflow suggests strong influence from hurricanes on the generation of turbidity currents in the Gulf of Mexico. 2020, Journal of Marine Science and Engineering 8 U.S. Geological SurveyNorthern Prairie Wildlife Research Center 2018.
2020-5-18During the extensive collapse of the Xingtai gypsum mine in China, M L 3.1 magnitude was measured. Twenty miners died underground and 17 residents on the surface. Furthermore, 88 living rooms were destroyed and eight shafts were badly deformed and later abandoned Wang et al., 2008. The most spectacular disaster happened in 1980, when a salt.
Hyperspectral high spatial resolution HyMap data are used to map mine waste from massive sulfide ore deposits, mostly abandoned, on the Iberian Pyrite Belt southwest Spain. Mine dams, mill tailings and mine dumps in variable states of pyrite oxidation are recognizable. The interpretation of hyperspectral remote sensing requires specific algorithms able to manage high dimensional data.
