Impact of Increased Water Inflow on Main Drainage System Efficiency in Mine

Journal of Mining Science, 2023
Рассмотрено 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, 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.

Prediction of Mine Water Inflow Based on Support Vector Machine

2011 Workshop on Digital Media and Digital Content Management, 2011
The 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.

Simulation of mine water inflow and gas emission during longwall mining

Rock Mechanics and Rock Engineering, 2008
Reliable prediction of rock mass deformation, mine stability, mine water inflow and mine gas emission is not only essential for improving mine safety and reduction of coal production costs, but also important for the assessment of environmental impact of mining.

Treatment of water inflow from flooded underground mines

Mining informational and analytical bulletin, 2020
The 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 ...

Calculation of mine water inflow using interactively a groundwater model and an inflow model

International Journal of Mine Water, 1987
The 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.

Studies in the prediction of water inflows to longwall mine workings

International Journal of Mine Water, 1986
The 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 ...

Evaluation of mine water inflow quality based on multiple methods

Journal of Environmental Engineering and Science, 2023
To 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.

Partitioning prediction on the risk of water inflow in the first mining area of Zhangjiamao mine

2011 International Symposium on Water Resource and Environmental Protection, 2011
In the light of the surfacing cracks and the shortage of water resources problems resulted from mining of Zhangjiamao mine. According to analyses of water-filling factors for the first mining area, this paper selects the formula in the Standard on the Exploration of Hydrogeology and Engineering-Geology in the Mining Area (GB12719-91) ( Standard for ...
