Influencing Factors Analysis of Floor Water Invasion Prediction Model

Floor water invasion is one of influences on mine safety.Water invasion models were complicated and various,under different conditions,water invasion models were different leading to the analysis uncertain results.Floor water invasion model was built by compound analysis technology and its uncertainties were analyzed in this paper.The risk of floor water invasion was zoned and influencing factors were sorted by sensitive analysis technology.Experment results show that equivalent thickness was the most important factor for reference to make decision of flooding prevention and cure.
