Coal mining, regarded as a high-risk industry, has a strong demand for virtual reality (VR) to fulfill safety and emergency rescue training. In the past ten years, VR technology has significantly improved miner training on both the hardware and software side. However, it still has some drawbacks, such as expensive and unsuitable hardware, lack of satisfactory user experience, without direct browser access, and lack of humanized and intelligent design. To solve these problems, a cloud-based VR system is designed for the training of coal miners in this paper. The system, with browser/client architecture, includes eight modules demonstrating the full procedure of an underground coal mine. The online cloud-rendered video streaming is adopted to provide enough computing and rendering power and hence a better browser-based user experience. Furthermore, game artificial intelligence (AI) is also introduced into the system to increase the emotional exchange between the system and users. Unlike traditional VR training software, this system designs two virtual miners to enhance the experience of trainees. The first virtual miner is a task-oriented non-player-character (NPC) which conveys general knowledge about the mine and guides the users in visiting the underground work sites. The second virtual miner is a disaster-oriented character which prepares the users for typical disasters. The system has been successfully implemented in a laboratory environment, and its performance has been validated. Yet, further practices are needed to stimulate more innovative applications of VR-based miner training and disaster drilling.

Water pollution hazard created by benzene series fire accident is very strong and it involves many fateful consequences. Along with the continuous improvement of society, people all over the world attach great importance to environmental protection and the sustainable development of economy increasingly. Along with the advance of fire protection cause of our country, the consciousness and concepts of "green fire" enjoy popular support. Therefore, study on the environmental materials and the establishment of emergency rescue procedures for water pollution accident created by benzene series fire is imperative.

As metro systems are becoming more and more widely used, all kinds of emergencies happen from time to time. A series of cases indicate that inefficient emergency response is a dominating cause of tremendous casualties and losses. The fast and valid allocation of emergency resources after the occurrence of metro emergencies has become a key point in improving the sustainability of metro operations. However, few studies have attempted to determine the allocation of emergency resources in metro emergencies. In this study, considering the unpredictability of different emergency scenarios in the metro system, the scenario-response mode was applied in the resource allocation decision. In this mode, a metro emergency scenario framework was first constructed through the identification of metro emergency elements. Next, a multi-objective model was established for the allocation of emergency resources in the metro emergency rescue process using a scenario-based analysis. The model aims to minimize both the penalty costs due to delays and the sum of allocation costs. The particle swarm optimization algorithm was adopted to solve the model. Eventually, a fire accident scenario at Nanjing Metro was applied to verify the feasibility and validity of the presented model and algorithm. The research results not only enrich and improve metro emergency management theoretically, but also enhance metro emergency rescue ability in practice.

The purpose of the study. The purpose of research is to substantiate and develop a multifunctional training complex for preparing cadets to conduct emergency rescue operations and fire-fighting by the usage of virtual reality technology. The relevance and necessity of developing a training complex are due to the professional activities of fire-fighters, related to the protection and rescue of citizens and the state from fires and the peculiarities of the educational process being implemented. The problem of effective formation of professional competencies in the field of fire-fighting is caused by the limited training ground base of universities, which does not allow training at various residential, social, industrial, transport and other functional facilities, that requires their replacement with virtual analogues. In addition, the limited budget of training time and a large number of cadets studying at the university, who must have the skills and abilities to manage fire and rescue units, organize fire extinguishing and interact with other emergency services, require the introduction of digital technologies to increase the intensification of the educational process and expand its capabilities.Materials and methods. To perform research tasks, methods of scientific and pedagogical study were used, which included the analysis and synthesis of information in the field of creating and applying digital virtual reality for educational purposes, the activities of fire and rescue units during fire-fighting and the requirements of regulatory legal acts for the performance of their professional tasks. Methods of modeling, contextual, game and reflexive training were used to form methods of preparing fire-fighters in virtual reality, recreating the professional environment.Results. The research of the activities of professional fire-fighters, the peculiarities of the educational process implemented at the universities of EMERCOM of Russia has revealed deficiencies in the training of cadets for activities in the field of organizing and conducting rescue operations and fire-fighting. According to the investigation of the adaptation and usage of digital learning technologies to improve the professional competencies of graduates in the field of fire-fighting, the application of virtual reality technology was proposed that allows to simulate a professional environment and to organize it in both individual and group practical preparation of cadets to professional tasks on a variety of residential, social, industrial, transport and other functionalities in conditions of simulating various scenarios of the occurrence and development of fires. To organize the training of cadets, the requirements for the specification and technical characteristics of the equipment, the project of the training ground for the organization of virtual learning (which was physically implemented at the Ivanovo Fire and Rescue Academy of State Fire-Fighting Service of EMERCOM of Russia), system and applied software, basic objects, models and scenarios of fire spreading on them, a system for evaluating the tasks performed by the trainees were developed in common with closed joint-stock company “Institute of Telecommunications” (St. Petersburg, Russia). Conclusion. The result of the research is the first physical prototype of a multifunctional training complex to prepare cadets for emergency rescue operations and fire-fighting, where it is planned to conduct a pilot operation stage during 2021, expand the list of objects and scenarios for the development of fires and subsequently introduce it into the educational process. The technological and methodological experience gained in the process of designing, implementing and operating a multifunctional training complex is planned to be extended by scaling it to other universities of the EMERCOM of Russia, which will create and unify a single system of practical training of cadets in the field of fire-fighting, using virtual reality technology.
