Water Inrush Evaluation of Coal Seam Floor by Integrating the Water Inrush Coefficient and the Information of Water Abundance

International Journal of Mining Science and Technology, 2014
Abstract The method of singular coefficient of water inrush to achieve safety mining has limitation and one sidedness. Aiming at the problem above, large amounts of data about water inrush were collected. Then the data, including the maximum water inrush, water inrush coefficient and water abundance in aquifers of working face, were processed by the ...

Evaluation of Water Inrush From Underlying Aquifers by Using a Modified Water-Inrush Coefficient Model and Water-Inrush Index Model: A Case Study in Feicheng Coalfield, China

Hydrogeology Journal, 2019
Water inrush from underlying aquifers seriously threatens mining of Permo-Carboniferous coal seams in many North China coalfields. To evaluate the risk of water inrush from underlying aquifers, a modified water-inrush coefficient method—using the water inrush coefficient (T) and geological structure index (G)—and a water-inrush index model (WII model ...

Stochastic forecasting of mine water inrushes

Advances in Water Resources, 1980
Abstract An event-based stochastic forecasting approach is used to model water inrushes into underground works under karstic water hazard. The stochastic properties of inrushes are related to the statistical properties of fissures in the karstic rock.

Mine Water Inrush Mechanisms and Prediction Methods

2021
The study of mine water inrush can be traced to the 1940s when a Hungarian engineer, Weg Frence, proposed the concept of relative water-resisting layer aiming at the karst water inrush from coal floors (Qian et al., Key strata theory in ground control, China University of Mining and Technology Press, Beijing, 2000).
