Abstract


In recent years, with the increasing depth of coal mining, mining intensity, mining speed and scale of mining, coal mining groundwater threat, becoming more serious harm. The basis of accurate and rapid determination of water inrush water, quickly take targeted flood control measures, is a key technology to ensure that mine coal mine safety production. This article is designed to establish the mine water inrush based on ArcSDE spatial data engine technology and Microsoft SQL Server discriminant integrated information space database; introduces spatial data mining technology applied to mine groundwater analysis and Voronoi diagram-based methods and DEM digging a mine groundwater spatial association rules of the law of distribution of chemical types and groundwater chemical structure; study used mine water inrush discriminant model, focusing on the fuzzy discriminant model F value given right, and GIS-based water temperature to identify mine suddenly discrimination method of the water, and as a basis for building an integrated water level, water chemistry, water temperature in one of the mine water inrush discriminant model; mine water inrush based on GIS development discrimination system quickly. The main conclusions of this article and achievements: the establishment of a simple and practical comprehensive information of mine water inrush identification process system; mine water inrush to discriminant integrated information space database; Panyi coal water in the northern part of the study area along Panji back inclined toward a ribbon area mainly Cl-K Na water south of a centralized area for HCO3-K Na water, other distribution characteristics HCO3 · Cl-K Na water; Cenozoic aquifer water chemistry type single Cl-K Na water features; study area the Panji anticline closer to the coal measures water samples HCO3-concentration values, rules; Panyi Bayesian identification accuracy rate of 87.23 neural network identification accuracy rate of 87.23%, gray relational analysis discriminant 80.43% fuzzy comprehensive evaluation of the F value given the right identification accuracy rate of 93.48%, and integrated information discriminant results showed that the water temperature discrimination on water quality discrimination has played a certain role in support of the discriminant model has good discriminant effect; various spatial data and attribute data management system is developed based on GIS, three-dimensional visualization of the mine water inrush discrimination, and spatial data. and other functions, the system has a higher value. Innovation of this paper: (1) spatial data mining technology to mine groundwater analysis and Voronoi diagram-based methods and DEM excavated mine groundwater chemical type distribution law; (2) GIS-based water temperature to identify mine suddenly discrimination method of the water, and to build the mine water inrush of water level, water chemistry, water temperature in one comprehensive information discriminant model; (3) to develop a simple, rapid, practical mine water inrush based on GIS information quickly discrimination system;
