摘　　要：为了能使现场监测得到的数据和采矿时空关系有机地联系起来,以及做到整体预测分析和监控,达到评价围岩稳定性和开采安全性的目的,本文结合大安山煤矿的实际情况,基于东北大学虚拟现实系统软件开发出具有真三维场景以及带有虚拟漫游、数据库查询和交互控制功能的一整套三维可视化矿山系统,并在此基础之上对虚拟现实软件进行二次开发,加强其集成众多三维数据信息的能力。通过综合分析,得到了基本顶来压步距、超前支护压力及顶板来压破坏的形式与机理等结果,为进行有效顶板控制和安全开采提供科学依据。In order to achieve the organic connection between field monitoring data and mining temporal-spatial correlation, to make the whole predictive analysis and monitor, and to evaluate surrounding rock stability and safely mining, a set of 3D visualization mining system combined with the actual conditions of Da＇anshan coal mine has been developed. The mining system is based on Northeastern University virtual reality system software, which not only includes three-dimensional scenes, but also realizes the functions of virtual roaming, database information inquiry and interactive control. By the secondary development of virtual reality software, its ability of integrating 3D data is strengthened. Through comprehensive analysis of the data, main roof weighting length, advanced support pressure and failure mode and mechanism of roof weighting are obtained, which provides the scientific basis for roof controlling and safe mining.
