【摘要】 煤炭占我国能源消耗的主导地位,煤矿开采中矿难事故造成的人员伤亡和财产损失极其巨大,我国目前的煤矿开采技术、信息管理与处理方式落后于发达国家,成为制约我国煤炭行业发展的一个重要因素;文章利用虚拟现实技术构建矿道三维虚拟场景,并通过相关算法研究实现了煤岩喷突与瓦斯扩散事故的三维动态重现,测试采用某煤矿提供的实际地理信息数据;测试效果表明,该系统人机交互方便,显示效果逼真,可实现巷道整体监测和局部放大观测,为煤矿事故分析提供了直观有效的工具,对预防事故发生、降低事故灾害具有重大意义。更多还原

【Abstract】 Coal consumption holds the leading position in energy consumption in our country,while colliery accidents cause serious casualty and large expense.Our coal exploit technology,management and process method of colliery information falls behind that of developed countries and becomes one of the key points that restrict the development of the coal industry.Based on virtual reality technology,three-dimensional colliery scene is reconstructed and coal outburst and gas spread process is represanted with the research of realitive algorithm.The software system is tested with real colliery geographic information.Tests show that this system has nice human-computer interface and realistic effect in display.The colliery scene can be observed both panoramically and in detail.This provides a visual and effective tool for accident analysis,thus has great magnificence for preventing accidents and reducing the loss of damage.更多还原
