The composite lining is used to deal with the problem of high groundwater pressure and has been successfully applied in practical projects [5-11]. lining consolidation...

... ABSTRACT: The purpose of this study is to propose a new method for evaluating the migration of nuclides of uranium tailings paste backfill in groundwater. Uranium tailings reservoir is a significant threat to the nearby environment and the health of residents. Filling the uranium tailings...

... the pumping well) are due to the compression of the underlying aquifer from the extraction of groundwater. Over the range of bulk hydraulic conductivities expected for the rockmass (between 10 -6 and 10 -7 cm/s), our simplified model of the aquifer suggests that the bulk storativity is between 10 -3 and 10...

Our macroscopic observation of the geology in the Mogao area suggests that there exists a network of groundwater that is supplied from the basin...

... ABSTRACT: Explosives detonated in a surface construction blast produce large quantities of gases that expand rapidly to fracture the rock. The gases contain toxic fumes such as carbon monoxide. If explosives are detonated in the rock below groundwater level, gas bubbles containing toxic fumes...
