摘要
由于传统的矿山资料的收集和数据的管理周期长、成本高、管理滞后,很难对矿山地质灾害进行有效地、科学地、准确地预测、预报和防治。而MAPGIS作为一种新兴的交叉学科,在数据的采集、整理、分析和输出方面,具有空间性和动态性,能够有效的满足矿山环境监测技术的要求。本文首先借助于MAPGIS的强大的数据管理、空间分析运算功能,在矿上地质灾害原有数据类型的基础上建立地理空间数据库和属性数据库,使得数图相结合。然后根据动态检测和模拟功能使得MAPGIS能够对各种矿山地质环境进行有效的动态监测和分析,并且在耦合地面沉降模型的基础上,实现对矿山环境灾害的模拟。其中动态监测采用了GPSRTK技术,使在原有矿山地质环境底图的基础上又添加了现有的地面沉降的动态数据,实现新旧监测数据的对比。最后以湖南攸县兰村的几处矿点为例进行监测并提出了一些保护矿山环境的措施。
As data collection and management are of cycle length, high costs, management lags behind in the traditional monitoring method, it is difficult to realize effective, scientific, accurate prediction and control to mine environment disasters. MAPGIS is a jumped up cross-disciplinary, which has extensity and movability in data collection, collation, analysis and output connection. It can be used to effectively meet the mine environment monitoring technology. Firstly geo-spatial database and attribute database can be set up with the mine environment monitoring original data type by using the MAPGIS powerful data management and spatial analysis capabilities. The date can combine with figures. And then with the dynamic testing and simulation feature, a variety of mine environmental dynamic monitoring and analysis are carried out effectively on MAPGIS, and the mine environmental disaster simulations are shaped on coupling ground subsidence professional models. GPS-RTK technology is used in the dynamic monitoring. The existing ground subsidence of dynamic data is added to the original mine geological environment base map, so the old and new monitoring data are contrasted. Finally the monitoring to several ore spots in Lancun, Youxian, Hunan province as an example is presented and some measures to protect the mine environment are proposed.
