【摘要】 开采沉陷是煤矿区主要的环境问题,正确预测沉陷区发展演化趋势对防治开采沉陷带来的生态破坏、地表建筑损毁等具有重要意义。以GIS为平台,根据矿区开采规程中地面沉陷的计算方法,采用Visual Basic6.0作为前台开发工具,利用Access作为管理开采参数和沉陷观测数据的后台数据库,嵌入GIS的空间分析与可视化功能,实现基础数据的管理、沉陷量计算、等值线绘制等功能。该系统操作简单、实用,预测结果精度较高。更多还原

【Abstract】 Mining subsidence is a major environmental problem in a coal mining area,and the correct prediction of the development and evolution trend of subsidence is of great significance to the control of ecological destruction and surface building damage caused by mining subsidence.This system realized the management of basic data,the computation of subsidence value and the drawing-up of isoline by taking GIS as the platform,in accordance with the computation method of surface subsidence under terms of mining rules,by using Visual Basic 6.0 as the foreground development tool,utilizing Access as the background database of the mining parameters and subsidence observation data,and embedding GIS spatial analysis and visualization functions.This system is simple and practical and has higher accuracy and a certain popularized value.更多还原
