摘要

In order to efficiently and accurately predict the scope and degree of the coal mining subsidence, analyze the damage degree of the mining subsidence to the surface and buildings, in this paper, the design principle of the prediction analysis system for the coal mining subsidence was proposed, the information flow of the system was analyzed, the spatial database and the main function modules of the system were designed, and the key technologies of the subsidence prediction model based on masonry beam structure and the subsidence prediction model by the probability integral method based on the coupling of loose layer and bedrock were designed and implemented. The coal mining subsidence prediction system was developed by using GIS component, which better realized the map management, the information extraction, the calculation of the subsidence prediction model and the analysis of subsidence damage degree.%为高效准确地预测煤矿采煤塌陷范围与程度,分析塌陷对地表和建筑物的损坏程度,提出了煤矿区采煤塌陷预测分析系统的设计原则,分析了系统信息流程,设计出系统空间数据库及主要功能模块,设计并实现了基于砌体梁结构的塌陷预测模型、基于松散层与基岩耦合的概率积分法塌陷预测模型等关键技术,采用组件式GIS开发了煤矿采煤塌陷预测分析系统,较好地实现了图件管理、信息提取、塌陷预测模型计算和塌陷损坏程度分析等功能.
