矿区开采沉陷3维可视化研究

矿区开采沉陷实体在移动过程中,具有明显的3维空间特征。目前,对于开采沉陷空间信息描述以2维的剖面线、曲线或等值线居多,而2维图形对于开采沉陷实体移动变形的表达缺乏直观性和准确性。而通过研究开采沉陷实体的空间特征并采用相应的数据模型,可实现开采沉陷3维可视化表达。这将有助于更加直观、深入地研究岩层移动形式、地表塌陷和地物损害程度,同时,对于研究、理解开采沉陷规律和提高开采沉陷损害防治技术也将很有意义。

Study of Mining Subsidence Three- dimensional Visualization

During the process of mining,the entities of mining subsidence have obvious three-dimensional spatial characteristics.At present,the spatial information of mining subsidence is described mostly as two-dimensional section line,curve and isoclines,but those graphs are short of intuitional and exact expression of the entities of mining subsidence moving.So through the study of the entities of mining subsidence characteristics,we can use some data models to realize mining subsidence three-dimensional visualization.As a result of it,people can deeply and broadly understand the form of terranes moving and the ground subsidence and the degree of objects damaging.It is also significance to deeply understand the disciplinarian of mining subsidence and improve the technology of mining subsidence damage prevention.
