Numerical Simulation Study Of Water Inflow In Daping Coal Mine

This thesis takes Da Ping Coal Mine, which subordinates to Tie Fa Coal Industry Group Co. Ltd as an example and chooses numerical method to predict the mine water inflow by comparing and analyzing various methods. On the basis of analyzing the hydro geological condition and water filling factors in detail, the mine underground water numerical simulation model is set up by visual mudflow to predict the mine water inflow in the future three years. The number of mine water inflow in 2010, 2011 and 2012 respectively is 9.71 m3/h,9.73 m3/h and 9.75 m3/h.Through model checking, it is proved that this method to predict results is reliable and useful, which corrects the little bigger results got from big mine field.This predicting method and project has extensive applicability, and is instructive to the similar mine water inflow predicting for both home and abroad.
