Evaluation of mine water inflow quality based on multiple methods
Journal of Environmental Engineering and Science, 2023To reduce the negative impact of mine water gushing on the environment, it is necessary to evaluate the water quality. Taking the Pingdingshan coalfield as the research object, six components – namely, chroma, turbidity, total dissolved solids, total hardness, chloride (Cl−) and sulfate (SO4 2−) – were selected as index factors.

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 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 ...

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 ...
