红岭铅锌矿的虚拟现实系统

Hongling Lead-zinc Mine's Virtual Reality Technology

根据红岭铅锌矿的实际情况,基于VR技术建立了一整套矿山虚拟现实系统。针对VR技术在矿山中应用的不足之处,对虚拟现实系统构建软件进行了二次开发,加强其对外部数据的集成与可视化,实现对微震数据、应力场、位移场、塑性区以及理论计算结果的真三维显示。该矿山虚拟现实系统不仅包含了地表、工业场地、矿体、井巷、采场以及回采动画等矿山三维模型场景,还包含了一些数据、数值结果的显示,具有虚拟场景漫游、信息查询、数据立体呈现和交互控制等功能。针对红岭铅锌矿的大量采空区,通过对虚拟现实系统中众多重要三维数据的联合解读和分析,实现对采空区围岩稳定性的评价以及危险区域的确定,提高了VR技术在矿业领域的应用性。

Combining with actual situation of Hongling Lead-zinc Mine,a set of mine virtual reality system based on the virtual reality technique was built. According to the shortcomings of the application of virtual reality technology in mine,the vir-tual reality software was secondly developed to strengthen the integration and visualization of the external data and to realize the true 3D display of seismic data,the stress field,displacement field,plastic zone and the theoretical results. This mine virtual re-ality system not only contains the 3D mine model scene,such as surface,industrial sites,ore,stope and drift,mining technology of animation,but also includes a display of some data,the numerical results. The system has the functions of virtual scene roa-ming,information query,data stereo presentation and interaction control function etc. Due to a large number of mined out area in Hongling Lead-zinc Mine,the stability of goaf is evaluated,the dangerous area is determined to improve the application of virtual reality technology in mining areas,through the interpretation and analysis of these important 3D data.
