Studies in the prediction of water inflows to longwall mine workings
International Journal of Mine Water, 1986The paper decribes results of mathematical investigations into the prediction of mine water inflows to longwall coal workings. Numerical calculations are reported on the basis of experimentally deduced hydraulic conductivities above longwall panels. The effect of longwall working on hydraulic conductivities is investigated by mathematical analyses of ...

Water Inflow Quantity Evaluation and Prediction for Cimushan Tunnel
Advanced Materials Research, 2012Tunnel excavation breaks the original hydrological dynamic balance, promotes water cycle and influences the mountain groundwater system to some extent. Water inflow during construction not only threatens construction safety, but also affects surface vegetation’s growth.

Predicting external water pressure and cracking of a tunnel lining by measuring water inflow rate
Tunnelling and Underground Space Technology, 2018The flow of water into a tunnel, through the surrounding rock mass and the tunnel lining, has important implications for tunnel design and tunnel condition assessment. The hydraulic conductivity of the lining is a major controlling factor on the water inflow rate.

Significance of Geological Parameters for Predicting Water Inflow in Hard Rock Tunnels
Rock Mechanics and Rock Engineering, 2013One of the most challenging aspects of tunnelling is prognostication of water inflows. More reliable prediction of groundwater inflow may give considerable economical saving for future tunnel projects and may also prevent damage of environment and installations on the surface.

Abstract Reliable scheduling of storage water in connected dams of hydro system based on the prediction of inflow rate was investigated. The amount of storage water was predicted in all dams which were connected to the hydro system. An optimal time scheduling of waste water discharge was derived by an appropriate usage of the storage water in the ...
