Study of Bedrock Weathering Zone Features in Suntuan Coal Mine
Lithological characteristics, mineral composition, physical properties of water and physical and mechanical properties, weathering zone distribution and other factors of bedrock weathering zone in coal-seam roof determine the strength of its watertight performance, while its performance has a direct impact on impermeable overlying loose surface water aquifers as well as the possible collapse in...
متن کاملWeathering Controls on Mechanisms of Carbon Storage in Grassland Soils
On a sequence of soils developed under similar vegetation, temperature and precipitation conditions, but with variations in mineralogical properties, we use organic carbon and C inventories to examine mineral protection of soil organic carbon. In these soils, C data indicates that the creation of slow-cycling carbon can be modeled as occurring through reaction of organic ligands with Al and Fe ...
متن کاملPredicting Changes in Coating Properties during Weathering
Coatings are very important for controlling appearance of, and providing protection to, equipment and infrastructure components. The weathering durability of coatings is thus a very important determinant of the lifetime of the equipment. Coating properties may be related to how the surface or bulk of the coating are affected by the environment. Gaussian statistics or Monte Carlo simulations may...
متن کاملFugitive Emissions from a Dry Coal Fly Ash Storage Pile
Standardized estimates of fugitive emissions resulting from bulk materials handling are subject to many potential uncertainties based on the material of interest, the specifics of operational handling, and local geography and meteorology. In 2011 EPRI undertook the first of 3 phases of a field monitoring study at a power plant that investigated fugitive emissions of PM2.5 and PM10-2.5 (“PMc” fo...
متن کاملLeaching of Major and Minor Elements during the Transport and Storage of Coal Ash Obtained in Power Plant
In power plant, coal ash obtained by combustion is mixed with river water and transported to the dump. Sequential extraction was used in order to assess pollution caused by leaching of elements during ash transport through the pipeline and in the storage (cassettes). A total of 80 samples of filter ash as well as the ash from active (currently filled) and passive (previously filled) cassettes w...
