“…Therefore, studying the combustion of multiple combustibles and the diffusion of toxic and hazardous gases in different locations underground will effectively manage mine fires [5,6]. In this paper, based on a mine, we will establish a threedimensional visualization ventilation model of this mine through Ventsim software and conduct fire simulation [7,8], compare the fire events caused by different locations and different fuels in the underground, analyze the change pattern and influence range of temperature, CO concentration and visibility at different times and locations under different working conditions, and provide the future treatment of similar events in the underground coal mines theoretical basis, and provide an important realistic reference for effective personnel escape and rapid development of emergency rescue strategies underground [9][10][11][12].…”

Mine fire is a very dangerous underground disaster. In order to better study the situation and influence range of mine fire, this paper uses Ventsim to establish a three-dimensional visual ventilation model of Yushuling coal mine. The fire simulation of coal mining face and central substation is carried out by simulation method to study the change law of CO concentration, visibility and temperature in different places. The results show that the CO concentration and visibility change greatly in the downstream of the fire source point when a fire occurs in the coal face; As for the temperature, the temperature at the fire source varies greatly, and the temperature below the inclined air shaft hardly changes; All of them show a decreasing trend with the increase of the distance from the fire source; In case of fire in central substation, there are great changes in all substances in the roadway before and after the air door is opened and closed; After the air door is closed, the CO concentration drops sharply, the change rate at the end of the fire is reduced, the end time is advanced to half of the original, the temperature change is relatively small, and the visibility remains low for a long time after the damper is closed and the recovery time is late. The research results have important guiding significance for the escape of underground fire.

“…Currently, closed-type parking lots have become an integral part of the infrastructure of various cities of the world [1][2][3][4][5][6], due to the rapid growth in motorization, while the number of parking spaces is lagging behind. In closed car parks, there are risks that are associated with the release of harmful substances from the exhaust gases of cars into the surrounding air, thereby creating high fire loads in emergency situations.…”

Today, this topic is relevant due to the fact that smoke and toxic combustion products that are released during fires are the main cause of death. According to statistics, about 42% of victims of smoke exposure get severe poisoning, eventually leading to death. At the same time, 70% of all those killed in a fire die precisely from the effects of smoke. The article discusses two types of smoke removal systems for closed car parks (traditional and impulse), analyzes the design features of these systems, performs calculations and evaluates the profitability of these systems in terms of energy consumption and economic costs.

“…Many scholars have conducted related research on emergency rescue of spontaneous combustion, which mainly focuses on emergency response systems [7][8][9][10], emergency rescue capability [11][12][13][14], etc., but less research exists on the generation of emergency response plans for spontaneous combustion.…”

In order to avoid missing the best opportunity for emergency rescue in the event of spontaneous combustion and to prevent accidents from developing further, this paper proposed a method to generate an emergency response plan for spontaneous combustion based on case-based reasoning (CBR). Firstly, we adopted Hadoop big data retrieval technology to establish a case library for spontaneous combustion; then, our team applied CBR technology and introduced the differential determination symbol to calculate case similarity; furthermore, we quickly generated an emergency response plan for spontaneous combustion with the help of the Python program; and finally, we used a case to verify the effectiveness of the method. Overall, the results showed that the emergency response plan generated using this proposed method was consistent with the actual situation of the accident case and, compared with other relevant representative algorithms, the results in this paper were more accurate. In practice, this method may be helpful in providing support for generating emergency response plans for spontaneous combustion.
