Definitions

  • the invention relates to a device for underground explosion protection in the form of one or more extinguishing agents and these extinguishing agents in the event of an explosion releasing container (s).
  • the pressure wave In the event of an explosion, the pressure wave either tilts them out of their metastable equilibrium position or destroys them and in the process distributes the extinguishing agent previously stored in a locally defined manner over the cross-section of the cavity.
  • the corresponding effect also achieve the hitherto less widespread release locks, which consist of pressure tanks filled with extinguishing agent or the water trough locks described above, but which are triggered via an explosion flame detector with downstream explosive devices to release the extinguishing agent.
  • the present invention has therefore set itself the task of the known effectiveness of previously used explosion barriers with a spatially much more variable provision of all possible extinguishing agents, such as, for. B. to combine water or rock dust.
  • each container used for extinguishing agent storage consists of flexible, extinguishing agent-tight and officially approved material and the respective spatial dimensions, both in terms of its shape and size as well as its local location in the explosion-free normal state Conditions in underground caves of mining and tunneling can be optimally adjusted.
  • variable design options of the containers according to the invention for example sack-shaped (), sausage-shaped (2) or tubular (3), the containers being able to be subdivided into individual bulkheads by means of intermediate walls which are impermeable to extinguishing agent desired size also a extinguishing agent supply allowed in such places in underground cavities where the loading of rigid containers is difficult or impossible to carry out, even though these places are not used by normal underground operations.
  • the extinguishing agent containers made of flexible material do not have to be deposited on a rigid scaffold, but instead are instead individually suspended (1, 2, 3) or in one, for example on one or more rope (s) one or more ropes (s) of individually suspended net (4) can be kept in front, which further increases the possibilities of adapting to the given spatial conditions in the underground cavity.
  • the material for producing the extinguishing agent container is selected such that it has sufficient strength to enclose the extinguishing agent in the undisturbed hanging state of the container, but tears when a pressure wave occurs. It can also be chosen so that it is primarily destroyed only at an incorporated predetermined breaking point in the event of an incident pressure wave. Another possibility is the use of material which remains undamaged even when a pressure wave occurs if the extinguishing agent container is coupled in this case to a pressure and / or radiation detector with a downstream explosive device or mechanical device for releasing the extinguishing agent.

Abstract

Dispositif de protection contre les explosions dans les travaux souterrains composé d'un ou plusieurs récipients de matériau d'extinction en matière flexible, étanche au matériau d'extinction et conforme aux réglements. Les récipients sont adaptés d'une manière optimale en grandeur et en forme aux proportions des locaux souterrains et sont déposés sur des charpentes de support ou dans des filets suspendus, ou bien ils sont suspendus à des câbles. La libération du matériau d'extinction - par ex. de l'eau, de la poudre minérale incombustible ou de la poussière - a lieu dans le cas d'une explosion par la destruction des récipients sous l'action directe de la pression et/ou de l'onde de chaleur, ou par la pression et/ou par des détecteurs de rayonnement faisant détoner des charges explosives et/ou par des dispositifs mécaniques appropriés.
