A Cellular Automata Optimization and Guidance Method for Mine Fire Escape Path

Abstract

The invention discloses a cellular automaton optimization and guidance method for a mine fire escape path, which belongs to a mine fire safe escape method. Including underground monitoring subsystem, smoke migration simulation subsystem, escape path selection subsystem, rescue and escape command and guidance subsystem, the monitoring system is composed of a ground central station and various sensors in the mine, monitoring temperature, gas and smoke parameters in real time; The smoke migration simulation system uses FDS software to simulate the dynamic evolution of smoke from underground fires; the escape route selection subsystem uses cellular automata to establish a mathematical and physical model of the mine's wind network structure, and dynamically quantifies the complex roadway environment and smoke pollution range , calculate the escape efficiency and determine the best escape route; the rescue escape command and guidance subsystem combines the calculation results of the escape route to provide guidance for the underground escape personnel, and uses the host computer and the underground voice alarm system to feed back the optimal escape route to the underground personnel. Improve escape efficiency in an all-round way and minimize casualties.

Description

technical field [0001] The invention relates to a method for a mine fire escape route, in particular to a cellular automaton optimization and guidance method for a mine fire escape route. Background technique [0002] Coal mine accidents occur frequently in our country, and often cause serious casualties and property losses. Among these disasters, fire accident can be said to be the most serious mine disaster. When an underground fire occurs, the underground environment is complex and harsh, and the roadways are staggered into a network, and the actual conditions of each roadway are different. Due to the narrow space in the coal mine, the complex environment, and insufficient oxygen supply, a fire will produce a large amount of CO, CO 2 And other toxic and harmful gases, especially when the fire occurs in the air intake area, these toxic fumes will spread to each working face with the wind, causing the poisoning and suffocation of the operators in the well. The smoke will ...

Problems solved by technology

[0005] Most of the emergency rescue after a mine fire takes into account the evacuation speed and safety exit distance, and most of the research on evacuation routes starts from a qualitative point of view, lacking quantitative mathematical analysis and risk assessment. There are few studies on the influence of underground environment complexity on personnel escape

In the study of evacuation routes for emergency avoidance, it is rare to analyze the impact of roadway environment on personnel escape from a quantitative perspective, and there is a lack of quantitative mathematical analysis and difficulty evaluation
