Application of GM Model in Coal Mine Water Inflow Prediction

2015 Seventh International Conference on Measuring Technology and Mechatronics Automation, 2015
The aim of this study was to predict groundwater inflow of Bangladesh Barapukuria coal mine using grey theory. The mine water inflow is affected by geological and hydro geological conditions, precipitation, degree of exploration and mining conditions, as well as many incomplete and synthesis of uncertain or unknown factors, belonging to the grey system.

Predicting external water pressure and cracking of a tunnel lining by measuring water inflow rate

Tunnelling and Underground Space Technology, 2018
The 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, 2013
One 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.

Reliable Scheduling of Storage Water in Dams of Hydro System Based on Prediction of Natural Water Inflow

IFAC Proceedings Volumes, 1997
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 ...
