Description
Technical Field
The invention relates to the field of coal mine disaster prevention and control, in particular to an intelligent disaster-isolation folding curtain type water bag for a coal mine tunnel and an operation method.
Background
In a plurality of production activities such as coal exploitation, tunneling and transportation, a large amount of dust can be produced, especially when exploiting the high gas coal seam, still can make partial gas escape, the dust mainly comprises a large amount of coal fragments and rock powder, the operational environment of high concentration dust can not only make long-term staff easily suffering pneumoconiosis, but also can aggravate mining mechanical equipment's damage, when dust or gas concentration accumulate to a certain extent, fire and explosion accident take place easily under the effect of the heat source, in order to prevent the calamity to spread and prevent the production of secondary calamity, the installation of colliery production unit in coal roadway or the relevant tunnel of stope face separates the calamity water bag, because it is lower to separate the water bag cost and convenient to use, consequently, wide application is obtained.
However, the disaster-isolation mode of the traditional disaster-isolation water bag is passive explosion isolation, whether the traditional disaster-isolation water bag can isolate the explosion and whether the explosion-isolation effect is good or bad is influenced by a plurality of factors, such as the explosion source condition, the propagation distance and the like, and meanwhile, the traditional disaster-isolation water bag needs to be manually used for water supply, and because the installation position of the disaster-isolation water bag is usually positioned on a roadway roof, a plurality of inconveniences are brought to a worker for water supply.
The traditional Chinese patent with the grant number of CN206668315U discloses an explosion-proof water bag shed and a system, wherein the explosion-proof water bag shed consists of a plurality of explosion-proof water bags, when the explosion-proof water bags are subjected to explosion impact force, the explosion-proof water bags are turned over or broken, so that a disaster-proof effect is generated, but when the explosion disaster generates the impact force which is insufficient to enable the explosion-proof water bags to fall down, the device cannot play a role in disaster-proof and fire-extinguishing; the prior Chinese patent with the bulletin number of CN213139912U discloses a self-sealing explosion-proof water bag, and the sealing type disaster-isolation water bag prevents coal ash from entering the water bag and water in the water bag is not easy to spill; when a disaster occurs, if water in the closed bag body is not easy to spill, the disaster can not be effectively blocked after the disaster-isolating water bag falls. In addition, the conventional explosion-proof water bag has at least the following problems:
(1) The traditional disaster-isolation water bag can only perform one-time blocking on disasters after falling, does not have continuous water source supplement, and cannot form effective secondary blocking and prevent secondary disasters.
(2) The traditional disaster-isolation water bag can be used for passively blocking disasters or fires in a roadway in a water bag falling mode, and blocking is only limited to a top plate and cannot be performed on disasters in a full-section mode.
(3) When the energy generated by explosion is smaller than the falling acting force of the disaster-isolation water bag, the disaster-isolation water bag adopting the passive explosion isolation mode is not easy to fall, and flame generated by explosion is not blocked, so that larger loss is caused.
(4) The traditional disaster-isolation water bag is large in size, and the explosion-isolation water shed formed by the disaster-isolation water bags occupies most of the space of the roadway, so that ventilation, pedestrians and transportation of the roadway are affected when disasters do not occur.
(5) The traditional disaster-isolation water bag is only hung on the tunnel top plate as a water storage container, and can not continuously spray water and reduce dust when the dust concentration in the tunnel is too high.
Therefore, it is necessary to design a disaster-isolation water bag capable of continuously extinguishing and eliminating disasters, not affecting roadway ventilation, pedestrians and transportation, and also capable of covering and extinguishing disasters on a full section, reducing dust concentration and gas concentration and a device for automatically releasing the disaster-isolation water bag so as to solve the problems.
