摘要：

为了提高非煤矿山冒顶片帮VR培训效率，基于Unity3D、3DMax和Visual Studio 2019软件开发了包括预培训、隐患岩块识别培训和灾害现场逃生培训3个模块的矿山冒顶片帮事故教学培训平台。该平台采用虚拟教练进行示范性教学，指导受训者识别、清理隐患岩块和完成灾害现场逃生，并将虚拟教练培训与传统UI文字培训的效果进行对比，对受训者进行灾害现场逃生测试，完成VR虚拟教练培训平台的效果评估。结果表明：采用虚拟教练培训和UI文字培训的受训者的逃生平均用时分别为192.9 s和238.1 s，后者比前者多45.2 s；一周后重复测试结果，采用虚拟教练培训和UI文字培训的受训者平均用时分别为224.7 s（同比增加16.5%）和290.9 s（同比增加22.2%），后者比前者多66.2 s。前者逃生用时同比增加更少，表明基于VR技术的非煤矿山冒顶片帮教学培训平台可以促进受训者对培训内容保持更长久的记忆力，且整体培训效率更高，可有效提高受训者的安全意识和应急反应能力，具有良好的推广应用价值。

Abstract:

In order to improve the efficiency of VR training for non-coal mine roof fall，based on Unity3D，3DMax and Visual Studio 2019 software，a mine roof fall accident teaching and training platform has been developed including three modules：Pre-training，hidden rock recognition training and disaster site escape training.The platform uses 3DMax modeling software and Unity3D engine to complete the mining VR environment modeling，through the HTC VIVE equipment to complete the interaction between trainees and the mine virtual environment，using virtual coaches for demonstration teaching.Firstly，train the trainees through the mine knowledge question bank to improve the trainees’ cognition level of the mine，and then use the virtual coach to guide the trainee to identify and clear the hidden rock blocks and escape from the disaster site.The comparison of the training effect of the virtual coach and the traditional UI text was carry out，and the trainees will be tested on the disaster scene and the effect evaluation of the VR virtual coach training platform will be completed.The results showed that the average time of escape for trainees trained by virtual coach was 192.9 s，and the average time for trainees trained by UI text was 238.1 s.The latter was 45.2 s longer than the former.The test were repeated one week later. The average time of the trainees who trained by virtual coach was 224.7 s，and the average time of the trainees who used UI text training was 290.9 s.The latter was 66.2 s longer than the former.At the same time，compare to the first test，the escape time of trainees using virtual coach training increased by 16.5%，while the escape time of trainees using UI text training increased by 22.2%.The test results show that the VR technology-based non-coal mine roof fall teaching and training platform can promote the trainees to maintain a longer-term memory of the training content，and the overall training efficiency is higher than UI text teaching，which can effectively improve the trainees’ safety awareness and emergency response capabilities.Interviews with trainees show that the use of virtual coach training can better guide trainees’ attention，create an atmosphere of real-person teaching，and have good promotion and application value.
