本文针对开采沉陷地表移动变形计算问题,在GIS平台利用空间数据模型给出了预测计算中不同坐标系的转换公式及其空间数据库的构建,并讨论GIS与专业工程模型的耦合方法,提出了基于COM的模型耦合方法应用于系统的构架。实践证明,该方式下GIS与开采沉陷专业工程模型结合具有明显的优越性,对其他相关专业领域的耦合应用具有一定的借鉴意义。
As a new crossed technology, GIS has a powerful extending function on the spatial data process and analysis, and it has been widely used in many fields. In this paper, the transformation equations between GIS and working face coordinates is given so as to calculate the ground deformation clue to mining subsidence and create the spatial database with the spatial data model in GIS platform. Also, the coupling methodologies between GIS and professional engineering model are discussed and put forward a system framework by using general COM technology. It can be concluded that the proposed method can play an important role in integrating GIS with mining subsidence, and will hel PGIS as a powerful tool to be used in other related fields for further applications.
