基于ARCGIS的矿山开采沉陷灾害预警系统

Early warning system of mining subsidence damage based on ARCGIS

为了实现与环境协调的矿产资源开采,提出建立并开发了矿山开采沉陷灾害预警系统。以美国大型软件ARCGIS为开发平台,采用ARCMapObject开发方法开发了矿山开采沉陷灾害预警系统;建立了该系统计算参数的位移反分析模型,引入单纯形优化方法,编制了系统计算参数的位移反分析模块;进行了实例计算分析。第1个实例分析了某工作面开采引起的地表沉陷灾害,并与CXYJ2001的计算结果对比,验证了系统的计算可靠性,并展示了系统的功能。第2个实例是对江苏姚桥煤矿开采方案引起的地表沉陷灾害预警分析,优化了开采方案。研究表明,系统是实现与环境协调的矿产资源开采的重要辅助手段。最后,介绍了进一步工作的方向。

To realize the harmony both mining and environment, early warning system of mining subsidence damage is presented and developed. Firstly, based on analysis of the damage early warning system, taking ARCGIS as the work window, adopting the development method of ARCMap Object, the mining subsidence early warning system is developed. Secondly, the displacement back analysis model of the calculating parameters of the system is presented. And the displacement back analysis program based on simplex method is developed. Thirdly, two cases are studied. In case 1, the subsidence damage due to a workface exploitation is analyzed. The resulsts are compared with those of CXYJ2001, and the system is proved to be not only reliable but also perfect functions. In case 2, the mining damage early warning analysis in Yaoqiao mine, Jiangsu Province is performed. According to the analysis, the exploitation design is optimized. Those studies show that the system is the important auxiliary method to realize the harmony both mining and environment. Lastly, the future study aims are introduced.
