Study on the Stability of aquiclude in the Close-Distance Coal Seams Repeated Mining in the Jurassic Coalfield of Northern Shaanxi

open access: yesAdvances in Computer and Materials Scienc Research
The aquifer in the Salawusu Formation is extensively distributed within the Jurassic coalfield of northern Shaanxi, China. However, the fracture development in overlying strata induced by repeated mining of close-distance coal seams and the stability of the aquiclude remain unclear.

Hydrogeochemical processes of groundwater system and its mining-motivated effect in mining areas of Western China

open access: yesMeitan xuebao
The exploitation of coal resources will destroy the aquifer structure, disturb the groundwater system and produce a new water cycle model. As the focus of coal supply and production, the western mining area is short of water resources and fragile in ...
