【摘要】:為高效準確地預測煤礦采煤塌陷范圍與程度,分析塌陷對地表和建筑物的損壞程度,提出了煤礦區(qū)采煤塌陷預測分析系統(tǒng)的設計原則,分析了系統(tǒng)信息流程,設計出系統(tǒng)空間數(shù)據庫及主要功能模塊,設計并實現(xiàn)了基于砌體梁結構的塌陷預測模型、基于松散層與基巖耦合的概率積分法塌陷預測模型等關鍵技術,采用組件式GIS開發(fā)了煤礦采煤塌陷預測分析系統(tǒng),較好地實現(xiàn)了圖件管理、信息提取、塌陷預測模型計算和塌陷損壞程度分析等功能。
[Abstract]:In order to predict the scope and degree of coal mining collapse efficiently and accurately, to analyze the damage degree of surface and building caused by collapse, the design principle of coal mining collapse prediction and analysis system in coal mine area is put forward, and the information flow of the system is analyzed. The system spatial database and main function modules are designed and implemented. The collapse prediction model based on masonry beam structure and the probabilistic integration model based on the coupling of loose layer and bedrock are designed and realized. A coal mining collapse prediction and analysis system is developed by using component GIS. The functions of map management, information extraction, collapse prediction model calculation and collapse damage analysis are well realized.
