A Model Base Framework for the Risk Assessment and Prevention of Geological Disasters in Coal Mines

Abstract

To evaluate geological hazards in mines effectively and systematically, we proposed an object-oriented model base framework that realizes model management and model reuse. This framework supports model generation, data storage, operation, analysis, prediction and application and includes model building and model management. When building the model, 7 commonly used disaster assessment models are encapsulated as model classes and model instances that are represented as objects. Model management includes evaluation factor management, model addition, modification, deletion and so on. In addition, the framework makes full use of the spatial data processing capabilities of Geographic Information System (GIS) to perform spatial analysis and prediction. We also applied the framework to the serious exploitation area of a mine in the Fangshan District, Beijing. The results showed that the proposed model base has strong operability and practical value and could provide early warnings for the geological hazards of coal mine areas.
