Mobile steel refuge chamber

Abstract

The invention discloses a mobile steel refuge chamber. A simple chamber is dug nearby a working face where miners work for long time, the mobile steel refuge chamber is arranged in the simple chamber, and a chemical filling agent for full closing is integrally filled between the simple chamber and the mobile steel refuge chamber; the mobile steel refuge chamber is supplied with power by adopting a special cable and supplied with wind by adopting special compressed air; and a master power supply is controlled by adopting a gas power cut-off instrument at the interior, so that common civil electric appliances work safely. The mobile steel refuge chamber combines the advantages of a rescue capsule and the refuge chamber, and solves the problems of difficulty in underground transportation andreasonable arrangement, poor integral sealing property, low waterproof performance, low impact resistance, few daily functions and the like in the conventional rescue capsule. 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; and the steel refuge chamber has a working environment independent from a mine environment, provides ideal underground conditions for daily detection, monitoring and management, and meanwhile, builds a platformfor realizing digitalized mines.

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 roadways 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 si...

AI Technical Summary

Problems solved by technology

[0003] At present, the rescue chambers in the domestic market are bulky, and even after they are disassembled, they cannot be transported underground by manpower. However, there are no mechanical transportation conditions in some working faces (part of the mining roadway) on the actual site of the mine, resulting in unreasonable layout; even if the huge rescue chambers can be transported , Installation and use, directly stored in the roadway, not only affects the normal ventilation and transportation, but also belongs to the direct rigid resistance to the shock wave of the explosion and the shock wave of the flood, which may cause damage to the rescue cabin or overall displacement, etc.

Due to structural reasons, the layout may be unreasonable. In the end, it may appear that entering the rescue cabin to resist the explosion shock is not as good as entering the chamber to hide from the explosion shock wave, and entering the rescue cabin is submerged.

The existing rescue cabin is only used as a backup safety device for escape in case of a mine disaster, and has no practical value in daily life. It is an expensive burden for the daily production of the mine.
