Application of Dynamic Multilevel Base State and Various Granularities with Spatiotemporal Amendments in Mining Area Geological Environment

针对矿区地质环境污染面积动态变迁和实时监测问题,首先根据TGIS中的时间属性表达特性,分别将时间粒度表达和变粒度时空存储因子设计与现有的动态多级基态修正模型进行综合集成表示,提出了一种动态多基态变粒度的修正模型,实现了时间粒度动态变化过程中多基态自动确立问题;其次结合某矿区地质环境面积变迁的时空数据特征,分别设计了时空数据库的五库结构和数据库组织结构,实现了矿区地质环境面积变迁时空数据库的逻辑和物理结构设计;然后通过结合TGIS和视频播放器原理,实现了矿区地质环境面积变化场景的回放,并采用空间数据库查询语句实现了地质环境面积变化的超前预演;最后以某矿区地质环境数据为例,实践表明:动态多基态变粒度的修正模型可实时监测矿区地质环境类型面积的变迁过程,增加了复垦区域的面积,实现了矿区地质环境面积变迁数据的存储、再现和未来变迁的预演。

To solve the problem of dynamic changing and real-time monitoring of mining geological environment area, the dynamic multilevel base state and various granularities with amendments is proposed through time granularities and variable granularities storage factors are wholly integrated depending to the expression of time attribute in TGIS, so as to realize base state and history base state are quickly created in time granularities dynamic process. The five database structure and organization of spatiotemporal database are designed by combined with spatiotemporal data of a mining areas geological environment area, Then playback and advanced preview of area change scene are realized respectively by combing TGIS with video player and SQL.Finally spatiotemporal data of a mine geological environment type as example, the successful application states that the model can be real-timely monitored change of the geological environment areas, be improved the reclamation areas, and be realized the storage, reproduction and forecast of the mining geological environment area data.
