矿区开采沉陷时空信息动态模拟研究

Study of mining subsidence spatio-temporal information dynamic simulation

开采沉陷所涉及的信息具有多维性、复杂性和动态变化的特点,为实现其动态模拟,首先在研究开采沉陷地理空间实体的时空动态过程特征的基础上,结合地理信息系统、虚拟现实、多媒体及动画等技术,反演矿山开采沉陷这一时空地学现象和过程,进行可视化表达与动态模拟。模拟的结果有助于研究地表、岩层等地理实体以及生态环境,因为煤层的开采所造成的移动变形和破坏的规律,以便采用更好的控制模式,减少经济损失和开采损害。

Mining subsidence information （MSI） is multidimensional, complicated and dynamic. It is more important to realize effective dynamic simulation of MSI for the research of mining subsidence rules, the reasonable extracting of subterranean resource and the protection of mining subsidence destroy. Based on the research of mining subsidence spatio - temporal process, the visual expression and dynamic simulation of mining subsidence are inversed combining with technology such as geographical information system, virtual reality, multimedia and Animation. The result can be used to study deformation and failure rule of earth＇s surface, terrane, and biological environment, which is resulted from mining. So a better control mode can be used to eliminate economic losing and mining damage.
