Title: Set- up and Application of Evaluation Model for Coal Seam Floor Water Inrush Risk
Abstract: In this paper,the influence factors of coal seam floor water inrush were analyzed and summarized,and based on the systematic collection and analysis of the hydrogeological data of the mine,determination was made on the main factors affecting Ⅱ1 coal seam floor water inrush in Zhangcun Mine.Quantitave evaluation was carried out on the water pressure,the geologic structure,the thickness of water-resisting layer,the ground pressure during mining and so on.Based on the spatial analysis tool of GIS,a multi-originated information complex method was introduced,an evaluation model for coal seam floor water inrush risk was established,evaluation was carried out on the water inrush rick in Cambrian limestone of Ⅱ1 coal seam floor according to the practical data of the influence factors of this seam,and effective evaluation results of water inrush in this seam floor were obtained.
