Numerical Simulation on Water Invasion of Coal Mine

Abstract:

This paper presents the numerical simulation of groundwater flow and the prediction of drainage in the No.5 mine of the Feng-feng coal mine area, using the data from a water invasion. First of all, we build a mathematical model of groundwater flow according to the hydrogeological conditions. Then, the model is verified by the water invasion data. The measured and simulated water level fit well during the model verification. At last, the mine drainage was predicted using the established model. The results indicated that the coal mining below -100m would result in a large amount of drainage and relative high cost.
