基于虚拟仿真的煤巷掘进工作面综合防突实验系统的构建

Construction of comprehensive outburst prevention experimental system for coal roadway driving face based on virtual simulation

煤巷掘进工作面综合防突是煤矿防突工作的重点,涉及多种参数测试和流程,但是由于煤矿属于特殊行业,无法现场教学,也无法进行实验室模拟测试,仅展示图片和设备,较为抽象,学生难以理解。虚拟仿真煤巷掘进工作面综合防突实验系统以虚拟现实为实验手段,配合实物,构建了一个网络化、三维互动式的虚拟矿井环境平台,将场景和实验流程等通过虚拟现实技术呈现出来,并配以音频和文字。实验人员依次完成实验简介、实验背景、综合防突、实验教学、实践教学5个模块的学习,人机交互,从而完成相关实验。系统各模块支持反复学习、考核等必要的教学环节,很好地达到了煤巷掘进防突教学的目的。

Comprehensive outburst prevention in coal roadway driving face is the focus of outbreak prevention work in coal mines, which involves a variety of parameter tests and procedures. However, due to the fact that the coal mine belongs to a special industry, it is not possible to conduct field teaching and laboratory simulation test. It only shows pictures and equipment, which is more abstract and difficult for students to understand. The comprehensive outburst prevention experimental system for the virtual simulation coal roadway driving face takes the virtual reality as experimental means and cooperates with real objects, constructs a networked, three-dimensional interactive virtual mine environment platform, which presents the scene and experimental process through virtual reality technology, and is equipped with audio and text. The experimental staff can complete the five modules of learning and human-computer interaction such as the experiment introduction, experimental background, comprehensive outburst prevention, experimental teaching and practice teaching, so as to complete the relevant experiments in turn. Each module of the system supports the repeated learning, assessment and other necessary teaching links, and achieves the purpose of outburst prevention teaching in coal roadway excavation.
