Mine explosion-proof well lid safety air bag automatic plugging device

Abstract

The invention provides a mine explosion-proof well lid safety air bag automatic plugging device and is suitable for the field of mine safety. The system is based on basic structures of existing explosion-proof doors and covers. Overall structural design of the plugging device is conducted after the installation position and function implementation modes of the device are known. A reasonable plugging mode, a proper plugging body and a work mode are selected to ensure the plugging effectiveness. The work process of the device is completely controlled by automatic responses of a circuit control system, and the device is small in size, simple in structure and high in reliability; corrosion and aging caused by the outside environment are avoided, the maintenance cost is low, the device can be repeatedly used, and the structures of the existing explosion-proof doors and covers are little changed; the safety cost effectiveness is high, the indirect disaster reduction effect is remarkable, andthe survival rate of survivors after explosion accidents can be effectively increased.

Description

technical field [0001] The invention relates to an automatic sealing device for a mine explosion-proof manhole cover safety air bag, which is suitable for the field of mine safety. Background technique [0002] As a large coal mining country, my country’s annual coal mining accounts for about 37% of the world’s total, and coal resources account for more than 70% of the energy structure. The growing social economy requires more energy support, requiring the coal industry to increase mining output. On the other hand, the geological conditions of my country's coal deposits are complex, the distribution of mineral deposits is uneven, and the structure of the coal industry is diversified. All these have brought greater difficulties to my country's coal mining industry compared with foreign countries, and indirectly caused mine accidents in my country frequent pattern. In order to be able to continue safe and efficient production, a lot of research work has been done domestically, ...

AI Technical Summary

Problems solved by technology

[0003] Since the explosion-proof door and cover were designed, installed and used so far, it has shown its great role in protecting the main fan of the air shaft, but also exposed some other problems. When the shock wave breaks through the explosion-proof door and cover, due to its own structure The characteristics determine that it cannot be quickly closed again in a short period of time, which brings obstacles to the continuous normal ventilation of the mine where the explosion accident occurred, deteriorates the survival and self-rescue environment of the survivors in the mine, and aggravates the consequences of the accident
