Conclusion and Outlook

Abstract

Based on the regularity and characteristics of coal formation, water filling source and water filling mode, and according to the geological structure of coal-bearing strata and superposition relation of water filling source, this paper divides karst water system and the geological structure model of coal-bearing stratum in the main coal mine area in north China into five types. The main factors that influence the water damage of the floor are analyzed, and the methods of collecting, quantifying and dimensioning the main control factors are systematically summarized, and the main control system of floor water inrush is established. Information fusion technology is used to establish a JDL-type water inrush evaluation information fusion model based on GIS. On this basis, the theory and method of floor water inrush evaluation based on partitioned variable weight theory are studied by using variable weight theory. And the vulnerability index method based on the theory of partitioned variable weight is applied to evaluate the risk of water inrush on coal seam floor in Xiandewang coal mine of monoclinic order type and Wangjialing coal mine, which is a monoclinic inversion type.
