Mobile steel refuge chamber

Abstract

A mobile steel refuge chamber comprises that: a simple chamber (104) is dug nearby a working face where miners work, a disassemblable mobile steel refuge chamber lining (105) is installed in the chamber (104) with a distance over 100 mm between the chamber (104) and the lining (105), a conventional door (108), an exit door (107) and an emergency exit window (106) are disposed at an open side of the lining (105), and support of the open side is enhanced, the lining (105) has an exterior anti-bonding structure, a chemical filling agent is used for integrally filling the lining (105), a metal net is connected at the open side of the lining (105), concrete spraying is used for reinforcement and closing, a special compressed air ventilation device is adopted for daily ventilation and a special power supply line is adopted, and a main power supply of electrical appliances is controlled by adopting a gas power cut-off instrument. The decomposed small mobile steel refuge chamber is convenient for underground transportation and quick in installation, and is reasonably arranged at the site for naturally resisting flood hazards and explosion.

Description

technical field

[0001] The invention relates to a mobile steel refuge chamber. Background technique

[0002] The mine disasters that cause mass deaths and injuries in the process of mine production in my country are mainly gas explosions and floods. According to the summarization experience of accident survivors and participating rescue workers, it is known that the gas explosion accident has the characteristics of instantaneous occurrence and the impact force with super destructive force above 10Mp at the center of the explosion, which can seriously deform the steel rails and mine cars in the roadway Damage, the high temperature and toxic gas produced are enough to suffocate people to death within 3-5 minutes; flood accidents have the characteristics of submerging the roadway for a long time, miners are washed away by water waves, and are trapped for a long time; but the shock wave of gas explosion is not It will affect the chambers, blind alleys and dead end alleys on the...
