From the domestic and international researches on virtual reality in the field of coal mine,it can be found that most of researches were local or simple research.The overall achievement which truly integrated the research achievements of all stages,fields and links and made a breakthrough had not yet appeared.This paper summarized the research status the applications of virtual reality technology in the field of coal mine,including the virtual scene simulation methods,the virtual reality monitoring and control methods,the virtual planning methods and the “VR+AR” fusion design methods.The difficulties and problems existing in its application were analyzed,and the fusion design the fusion design methed which integrated multi-technology should be addressed.Firstly,we should solve the problems in technical training,data visualization analysis,virtual planning.Secondly,the problem of virtual monitoring and monitoring in the whole process of production should be solved.Thirdly,the above achievements and innovative breakthroughs should be used to realize the virtual design of mine intelligent equipment,especially to highlight the integration and interaction of virtual design and multi-links.The intelligent control platform will be integrated into the whole production control process.Finally,the goal of high intelligence,self-correlation,green,high efficiency and nobody on duty can be realized.
