| Virtual reality is a new and advanced technology that has developed in the last ten years, which is considered as one of the ten new and advanced technologies that will greatly influence human in 21st century. As the new stage of computer technology development, it presents vast application prospect. Currently, the technology has been widely applied to military affairs, aviation, medical treatment, entertainment, architecture, etc. In the foreign country, it also has been applied in coal mine field to some degree, but, in our country, it's application hardly begins. Virtual reality is a mighty complicated technology system based on computer graph theory, image progress and pattern recognition, intelligent interface technology, artificial intelligence, multi-sensor technology, voice process and sound technology, net technology, parallel process and high-powered computing. The application of the technology cannotbe imagined without proper application developing tools.For the purpose of seeking after the way of the application of virtual reality technology in the coal mine field, the research introduced a concept of assembly virtual mines developing system on PC,analysed the wanted function of the system, designed the function frame of it, studied the key technology of realizing it, finished a frame system and discussed the elementary application of the system.Using virtual reality technology, the author developed a virtual coal mine developing system based on PC.The system greatly decreases the difficulty of developing a virtual coal mine and raises the efficiency of development, provides a powerful tool for design, project decision and education. The successful development of the system will improve the application of virtual reality technology in the coal mine field the same as the CAD aid design systems have made computer technology applied in large scale. |
