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

Embodiment Construction
[0023] see figure 1 and figure 2 , the present embodiment provides an intelligent control method for emergency avoidance of danger in the event of an underground coal mine fire disaster, including the following steps:
[0024] (1) Set up a certain number of CO sensors, CH 4 Sensors, temperature sensors, building a gas monitoring and monitoring system, online monitoring of toxic and harmful gas concentrations and gas temperature indicators, providing decision-making basis for emergency disposal in mines;
[0025] (2) Boreholes are drilled above the surface of the corresponding positions at intervals of a certain distance for developing roadways, preparing roadways, and mining roadways;
[0026] (3) Set the gate and the storage space for the gate above the roadway roof below the corresponding borehole to ensure that the gate can be lifted up and down flexibly;
[0027] (4) The size of the gate should be adapted to the section of the roadway, and the installation position of ...

The invention discloses an intelligent control method for urgent danger prevention during underground coal mine fire disaster. The method comprises the following steps that firstly, a certain number of CO sensors, CH4 sensors and temperature sensors are arranged at fire easy-to-occur places of a development roadway, a preparation roadway and a mining roadway or on a mining working surface to forma monitoring system; poisonous and harmful gas concentration and gas temperature indexes are monitored on line, then holes are drilled above the ground surface at the corresponding positions of the development roadway, the preparation roadway and the mining roadway at certain intervals, gates are arranged, lifting rods are connected with the gates, and an electric lifting device is connected withthe gates for remote operation; and when the monitoring system monitors the highest values of the gas and the temperature, the disaster occurrence position is accurately judged, a gate control systemis started, and gate descending is directly and automatically carried out to enclose the disaster area. The intelligent control method can be applied to underground development roadways, preparation roadways and mining roadways; and the method is a model of intelligent emergency rescue, and has reference significance for rescue of other disaster 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 avoidance 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, and roof fall 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 injuries. , Severe cases lose their precious lives. 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 c...
