【摘要】：煤炭一直以来都是我们国家最主要的能源。矿山开采具有两面性,一方面它能极大地促进国民经济的增长;另一方面开采会导致地表沉陷进而严重损坏当地的生态环境。因此科学有效的管理沉陷数据并对开采损害进行分析和评价是十分有必要的。GIS是一门以计算机为基础的交叉性学科,不仅能够方便的管理空间信息,而且还有强大的空间分析功能,利用GIS对开采沉陷损害数据进行分析是切实可行的。本文借助Visual Studio2008开发工具,采用GIS组件式开发技术,以Arcgis Engine为二次开平台完成了开采沉陷损害分析系统的研发,使用面向对象的C#语言实现了开采损害分析的程序化和可视化。本文主要完成以下工作:利用概率积分法结合开采沉陷其他相关理论实现了对开采沉陷数据的管理和沉陷预计结果的可视化输出.,根据预计的移动变形信息生成沉陷区DTM和各种等值线;提供了工作面内下沉土方量和沉陷区道路修复方量计算方法;利用GIS的空间分析功能查询各个时刻沉陷范围内的地物;利用地图统计功能将地物的具体属性(主要是抗变形能力值)和预计的沉陷曲率变形DTM相结合,可以实现超变形查询和统计查询等功能,进而对因开采沉陷造成的受损房屋情况进行分析。本系统为用户提供了一个交互性良好的操作平台,对开采沉陷损害进行了可视化分析,在一定程度上指导了矿山生产以及开采沉陷防治工作。
[Abstract]:Coal has always been the most important energy in our country. Mining has two sides, on the one hand, it can greatly promote the growth of the national economy; On the other hand, mining will lead to surface subsidence and then seriously damage the local ecological environment. Therefore, it is very necessary to manage subsidence data scientifically and effectively and to analyze and evaluate mining damage. A cross-disciplinary discipline based on machines. Not only can manage the spatial information conveniently, but also has the powerful spatial analysis function. It is feasible to use GIS to analyze the data of mining subsidence damage. This paper adopts GIS component development technology with the help of Visual Studio2008 development tools. Taking Arcgis Engine as the secondary open platform, the research and development of mining subsidence damage analysis system is completed. The programming and visualization of mining damage analysis is realized by using object-oriented C # language. The main work of this paper is as follows:. Using probabilistic integration method combined with other relevant theories of mining subsidence, the management of mining subsidence data and the visual output of subsidence prediction results are realized. According to the predicted information of moving deformation, the subsidence zone DTM and various isolines are generated. The calculation method of the settlement earthwork quantity and the road repair volume in the subsidence area is provided. The spatial analysis function of GIS is used to query the features in the subsidence range at each time. By using the statistical function of map, the specific attributes of the ground object (mainly the value of anti-deformation ability) and the predicted curvature deformation DTM can be combined to realize the functions of hyperdeformation query and statistical query. The system provides users with a good interactive operating platform, and visual analysis of mining subsidence damage. To a certain extent, the mine production and mining subsidence prevention and control work.
