Mine fire escape route cellular automaton optimizing and guiding method

Abstract

The invention discloses a mine fire escape route cellular automaton optimizing and guiding method, and belongs to mine fire safe escape methods. An underground monitoring subsystem, a smoke plume migration simulation subsystem, an escape route selection subsystem and a rescue and escape command guiding subsystem are included, and the monitoring system is composed of a ground central station and various underground sensors and monitors temperature, gas and flue gas parameters in real time; the smoke plume migration simulation system simulates dynamic evolution rules of underground fire smoke through FDS software; the escape route selection subsystem applies a cellular automaton for building a mathematical physical model under the mine ventilation network structure actual condition, dynamically quantizes the complex roadway environment and the smoke pollution range, calculates the escape efficiency and determines the best escape route; the rescue and escape command guiding subsystem provides guidance for underground escape persons on the basis of the escape route calculation result, and the best escape route is fed back to underground workers by means of an upper computer and an underground voice alarm system, the escape efficiency is comprehensively improved, and casualties are reduced to the maximum extent.

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 influenc
