drilling holes above the ground surface at corresponding positions at certain intervals in a development roadway, a preparation roadway and a stoping roadway;
thirdly, arranging a gate on a top plate of the roadway below the position corresponding to the drill hole, wherein the size of the gate is adaptive to the section of the roadway, and the gate corresponds to the position below the drill hole;
step four, drilling a hole on the ground surface, connecting the lifting rod with the gate from the hole on the ground surface, connecting the gate by adopting an electric lifting device, ensuring that the gate can be lifted up and down, constructing a gate control system of the roadway, and in order to prevent the gate from being damaged when the gate is lifted up and down, requiring that a limiting device is arranged on the lifting rod of the gate, ensuring that the lifting height of the gate is not more than the height of the roadway, and the descending height is not more than the height of the roadway; in normal conditions, all the gates are in an open state and are lifted to the upper part of a top plate of the roadway, so that the normal use function of the roadway cannot be influenced;
integrating the gas monitoring and controlling system with the gate control system, performing remote operation through parameter setting,
when the monitoring and monitoring system monitors the highest values of gas and temperature, accurately judging the disaster occurrence position, starting a gate control system, and directly and automatically descending a gate to close a disaster area; or before the disaster area is closed, whether a person works or not is determined through a person positioning system, and if the person works, the person is orderly guided to evacuate and then closed.
The intelligent control method for emergency danger avoidance during fire disaster of underground coal mines can be applied to underground development roadways, preparation roadways and stoping roadways. After a coal mine underground catastrophe accident occurs, such as gas and coal dust explosion, coal and gas outburst, fire and the like, and under the condition of escaping or blocked escaping path, the valve is automatically opened in response to the monitoring and early warning threshold value of the toxic and harmful gas sensor in the first time, toxic and harmful gas is effectively isolated, high-temperature smoke is resisted, a safe closed space can be provided for people in danger and people who can not evacuate in time, and meanwhile, valuable time is won for emergency rescue, and favorable survival conditions are created. The method is a fastest protection mode of self-adaptation and self-perception when an emergency disaster occurs in a coal mine, and under the condition that miners cannot escape from a disaster affected area, the method provides the miners with an environment for maintaining life, obtains conditions of contact with the outside, and waits for rescuers to arrive, so that the success rate of rescue is improved.
Compared with the prior art, the technical effect who brings lies in:
(1) when fire disasters such as coal and gas outburst happen, the control can be carried out at the first time, the influence range is reduced, and favorable conditions are created for subsequent rescue;
(2) the intelligent control method is an intelligent control method for autonomous perception of the environment through integration of system monitoring and an automatic control system;
(3) when the disaster affected area is sealed, the sealing speed is high, the sealing section is large, and the effect is good;
(4) the closed gates can be started in groups, the limited space of the roadway can be flexibly closed, and the success rate of rescue is improved;
(5) the application is flexible, and the fire disaster can isolate the diffusion of toxic, harmful and high-temperature gases, and can also play a role in isolating air, so that the harm is reduced to the minimum degree;
(6) by intelligently controlling the catastrophe environment, the method is successfully applied not only as an important component of intelligent mine construction, but also as a model of intelligent emergency rescue, and has reference significance for rescue of other disaster accidents.
