Mine fire simulation experiment platform and experiment method

Abstract

The invention discloses a mine fire simulation experiment platform and an experiment method. The experiment platform comprises an air supply system, a simulation space system, a fire source simulationsystem and a data collection and feedback system. The ventilation network of the experiment platform and the internal resistance, width-to-height ratio and inclination angle of the roadway are easy to adjust, and the repeatability is high; various monitoring devices are used for monitoring the wind speed, the fuel mass change, the temperature, the density, the pressure, the O2 and CO concentration and the smoke spreading condition in real time when a mine fire occurs; the device can be used for researching the smoke migration rule of the mine fire, the design of alarm and air control measurescan quickly and effectively prevent the disaster situation from further expanding, the optimal scheme of fire fighting and personnel rescue is researched through a contrast experiment, the harm degree of accidents is reduced, and the device has important guiding significance for mine safety operation.

Description

technical field [0001] The invention belongs to the field of mine fire prevention and control, and in particular relates to a mine fire simulation experiment platform and an experiment method. Background technique [0002] Mine fire is one of the main disasters faced by coal mine safety production. Once a fire occurs, due to the closedness and narrowness of the underground space, not only the underground coal resources and production equipment will be burned, but even casualties will be caused. At the same time, a large amount of toxic and harmful smoke will be generated, causing some miners who could have survived to lose their lives due to poisoning. The ability to escape, expand the area affected by the disaster, and cause secondary disasters. Therefore, it is very important to study the smoke migration law and wind control measures in mine fires. [0003] At present, the network structure of the domestic mine fire simulation experiment platform is too simple, and the f...

AI Technical Summary

Problems solved by technology

[0003] At present, the network structure of the domestic mine fire simulation experiment platform is too simple, and the functions are not comprehensive enough to systematically simulate the movement state of fire smoke in the mine. There is a big deviation between the experimental data and the theoretical analysis.

Chinese patent application CN105894936A discloses a small-scale simulation test bench for external fires in coal mines. It can only simulate a simple roadway, and there is no wind resistance inside. Adjustment, can not simulate the fire spread of the actual underground ventilation network and the interaction between roadways, and there is no alarm control measures after the fire occurs
