Water inflow characteristics of coal seam mining aquifer in Yushen mining area, China
Arabian Journal of Geosciences, 2021The Yushen mining area is located in the arid and semi-arid regions of western China. Coal mining activities in this mining area face the challenges of water resource pollution. In this study, in order to study the water inflow law of aquifer caused by coal mining activities, the overlying strata of the mining seam are divided into four aquifer groups ...

Application of idealised analytical techniques for prediction of mine water inflow
Mining Science and Technology, 1985Abstract The paper highlights the importance of designing a mine water control system during the feasibility study stage of a proposed large mining project. A review of the analytical techniques available for the prediction of mine water inflow quantities is given.

Chinese Journal of Geochemistry, 2008
Through a systematic observation of water level and temperature, and a comprehensive analysis of the data on major/trace elements, nitrite, hydrogen-oxygen isotopes, the conclusion has been drawn that there are two relatively independent groundwater systems (cool water and hot water), and the geochemical indicators of hot/cool waters are described. The

Comparsion Study on Two Methods of Water Inflow Prediction of Coal Mining
Advanced Materials Research, 2015Because of the complex geologic space body and the underground seepage conditions, it is difficult to predict groundwater water inflow in prevention and treatment control work of coal mine. To predict the groundwater flow of the coal seam under the roof sandstone aquifer in Nanshan coal, the big water well method and three-dimensional numerical model ...

Simple Analytical Equations for Estimating Ground Water Inflow to a Mine Pit
Groundwater, 2000Abstract Steady‐state analytical solutions are presented for estimating the ground water inflow rate to a mine pit that may contain a pit lake of finite depth. The solutions consider (1) the effect of decreased saturated thickness near the pit walls; (2) distributed recharge to the water table; and (3) upward flow through the pit ...
