Evaluation of Water Inrush in Seam Floor Based on Multi-originated Information Complex

The water inrush from seam floor is the result of synthetic effect of multi-factors.By using the technique of multi-originated information complex,this paper analyzed main factors which affect the water inrush in seam floor and built up a model for water inrush adapting to Panxi Coalmine with a depth of 1000 m,combining with its former data of water inrush and evaluated the risk of water inrush from seam floor in un-mined areas and draws a map of risk degrees of water hazards.It is of important theoretical and practical significances for guiding the safe mining of the 19th seam in Panxi Coalmine.
