An intelligent control method for emergency avoidance in the event of underground coal mine fire disaster

Abstract

The invention discloses an intelligent control method for emergency avoidance in the event of a fire disaster in an underground coal mine. In the method, a certain number of CO sensors, CH 4 Sensors and temperature sensors constitute a monitoring and monitoring system, which monitors the concentration of toxic and harmful gases and gas temperature indicators online, and then drills holes above the surface at corresponding positions at certain distances from developing roadways, preparing roadways, and mining roadways, and sets gates, and connects the lifting rod with the gates. To connect, the electric lifting device is used to connect the gate for remote operation. When the monitoring and monitoring system detects the highest value of gas and temperature, it can accurately judge the location of the disaster, start the gate control system, and directly and automatically lower the gate to close the disaster area. It can be applied to developing roadways, preparing roadways, and recovery roadways in underground mines. It is a model of intelligent emergency rescue and has reference significance for the rescue of other disasters and accidents.

Description

technical field [0001] The invention belongs to the technical field of coal mine emergency management, and in particular relates to an intelligent control method for emergency evasion in the event of a fire disaster in an underground coal mine. Background technique [0002] As we all know, coal mining is a high-risk industry, which has been affected by fire, flood, gas, roof falling, etc. for a long time. A large number of such accidents occur in the coal mining industry every year, which will pose a huge threat to the safety of underground personnel, and at least suffer physical and mental harm. , In severe cases, precious lives are lost. Although our country has also researched and designed emergency hedging systems in recent years, they are basically based on the construction of some refuge facilities and emergency facilities with simple configuration and single function, and lack intelligent control technology for automatic identification of disasters. Through the analy...

Problems solved by technology

Although our country has successively researched and designed emergency avoidance systems in recent years, they are basically based on the construction of refuge facilities and emergency facilities with simple configuration and single function, and lack intelligent control technology for automatic identification of disasters.

Through the case analysis of a large number of emergency rescue accidents, especially after the fire and gas explosion accidents, due to the failure to isolate the toxic and harmful gases in the first time, and the response time of the rescue was not timely, the trapped people could not be evacuated urgently, which delayed the best rescue opportunity
