Prediction of water inflow of a coal mine of Shaanxi
Gong-kuang zidonghua, 2016 Main factors and indicators that affect water inflow of a coal mine of Shaanxi were analyzed according to its hydrogeological conditions. BP neural network and large-well method were used to predict water inflow of different working faces of the second and third districts, and results of the two methods were compared. The analysis results show that the

Predicting mine water inflow volumes using a decomposition-optimization algorithm-machine learning approach [PDF]
Scientific ReportsDisasters caused by mine water inflows significantly threaten the safety of coal mining operations. Deep mining complicates the acquisition of hydrogeological parameters, the mechanics of water inrush, and the prediction of sudden changes in mine water ...

Water (Switzerland)Mine water hazards represent one of the principal threats to safe coal mine operations; therefore, accurately predicting mine water inflow is critical for drainage system design and water hazard mitigation. Because mine water inflow is governed by the combined influence of multiple hydrogeological factors and thus exhibits pronounced non-linear ...

Simulation Of Mine Water Inflow: Case Study Of The Štavalj Coal Mine (Southwestern Serbia) [PDF]
Archives of Mining Sciences, 2015 Abstract The inflow of mine water to mining operations is often caused by random events such as precipitation. Consequently, the mine water inflow regime can be defined as a function of random events applying the theory of random processes. Regression models of the multiple linear correlation type have been used to simulate the inflow of mine water ...

Prediction of coal mine water inflow by different mining methods and environment impact analyses
Shuiwen dizhi gongcheng dizhi, 2023 Improper mining of coal mines can cause damage to water resources and the water environment, especially in areas with relatively fragile ecological environment. At present, the prediction of mine water inflow mainly focuses on the single working face or mining area, and enough attention has not been paid to the influence of long-term mining of coal ...

Fine Prediction for Mine Water Inflow on Basis of Visual Modflow [PDF]
International Journal of Oil Gas and Coal Engineering, 2019 Mine water inflow refers to the influx of mine within the mine construction and production process of water per unit time. The amout of water inflow is not only an important indicator of the technical and economic evaluation of mine construction and rational development but also the main basis for coal mining production design department to develop ...

Preliminary Prediction of Inflow into the D-Holes at the Stripa Mine [PDF]
, 1990 Lawrence Berkeley Laboratory (LBL) is contracted by the US Department of Energy to provide an auxiliary modeling effort for the Stripa Project. Within this effort, we are making calculations of inflow to the Simulated Drift Experiment (SDE), i.e. inflow to six parallel, closely spaced D-holes, using a preliminary set of data collected in five other ...

Preliminary study on Applicability of mine water inflow forecasting method
IOP Conference Series: Earth and Environmental Science, 2020 Abstract The commonly used calculation and prediction methods of mine water inflow in China are divided into deterministic and non-deterministic. Affected by many influencing factors, the applicability of the calculation method has not been reflected, resulting in a large prediction error.

Prediction of Mine Water Inflow Based on Growth Curve Model
Academic Journal of Science and TechnologyDuring the construction and operation of a coal mine, water inrush incidents frequently occur. Minor water-related accidents can cause delays in mining operations, while major incidents can result in significant losses and casualties. This paper takes a coal mine in Shanxi as a case study, employing growth curve models and optimal weighted coefficient ...
