Simulation Of Mine Water Inflow: Case Study Of The Štavalj Coal Mine (Southwestern Serbia)
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 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 ...
