Impact of Increased Water Inflow on Main Drainage System Efficiency in Mine
Journal of Mining Science, 2023Рассмотрено влияние водопритока на работу главной водоотливной установки подземного рудника “Удачный” АК “АЛРОСА”. Установлено, что содержание твердых частиц в шахтных водах повышается при росте водопритока в рудник. Предложен способ по недопущению попадания в рудник в теплое время года дополнительного водопритока, обусловленного планируемым демонтажем

Application of GM Model in Coal Mine Water Inflow Prediction
2015 Seventh International Conference on Measuring Technology and Mechatronics Automation, 2015The 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.

Prediction of Mine Water Inflow Based on Support Vector Machine
2011 Workshop on Digital Media and Digital Content Management, 2011The prediction of water inflow is significant to the preventing and controlling water of mine pit. In this paper SVM is applied to the prediction of water inflow, and the workflow and prediction model is given. Combing with the practical demands, a prediction was made about water inflow of a new working face.

Treatment of water inflow from flooded underground mines
Mining informational and analytical bulletin, 2020The study focuses on the adverse effect exerted on the environment by temporary shutdown and closure of underground mines by means of flooding. Closure of underground mines only terminates the structural and technological transformation of geological rock mass while detrimental effect on the natural environment of underground mines remains and even ...

Analytical techniques for the estimation of mine water inflow
International Journal of Mining Engineering, 1985This paper outlines various analytical techniques for mine water inflow estimation incorporating several refinements such as finite boundary conditions, linear, fracture and turbulent flow conditions to pumping wells and underground excavations. These modifications enable practical mining to be simulated and therefore, permit more accurate predictions ...

Calculation of mine water inflow using interactively a groundwater model and an inflow model
International Journal of Mine Water, 1987The uncertainty of the pre-evaluation of potential ground water inflow rates in underground mines results in difficulty in planning and costing the water related activities of the mines. This paper presents a procedure for making a rational assessment of the potential inflows.
