Way to isolate the emergency fire site of mine

 

The invention relates to fire fighting equipment and can be used to isolate the emergency fire sites of mine. To increase the effectiveness of fire suppression in mines mines due to exclusion of fire from the existing mine workings and its suppression layer solid filler serves for insulating the jumper from the current part of the excavation with simultaneous submission of the fill under a layer of dry filler in the pipeline, at the same time as fill use water or foam obtained in the area of emergency fire area. 2 C.p. f-crystals, 1 Il.

The invention relates to fire fighting equipment and can be used to isolate the emergency fire sites of mine.

Well-known combined the foam containing the generator, located below the air-foam barrel with ploskostiam the nozzle through which the formed medium expansion foam gets on a flat jet of low expansion foam and transported to the fire. C. the USSR №1086601, class. And 62 With 31/12, 1983).

A disadvantage of the known device and implemented in the way it combined the foam is that the formed layer is rather low fire-extinguishing ability.

There is a method of extinguishing a fire and a device for its implementation, where the method consists in the preparation of foams of different multiplicity and applying it to the fire in a layer one expansion to another layer ratio, the foam layer of the same multiplicity pre-saturated with finely dispersed Sol substances with high inhibitory effect, and the device for fire extinguishing contains a foam generator with a nozzle spray foam solution and pocketmoney nozzle located underneath Peniscola with ejector with a pyrotechnic gas generator (the description of the invention to the patent of Russian Federation №2102093, class. And 62 With 2/00, 1998).

The disadvantage of this invention is that the proposed technology ensures the production of high foam inhibiting action and creation in the movement path of the fire inert foam veil, which, however, due to syneresis foam collapses, which reduces the security.

The closest way of isolating emergency fire site of mine is a method disclosed in the description and.with. The USSR №1700264, CL E 21 P 5/00, publ. 23.12.1991 and contains the following common characteristics with the claimed invention: supply of expanded inert backfill suspension for isolating the jumper from desti fire fighting in the way of insulation emergency fire site of mine, introducing insulating barrier jumpers of foamed inert backfill slurry supplied for isolating the jumper from the active part of the mine workings, the layer of dry particulate filler suspension is served concurrently with the cooling of the suspension, and the fill is served under a layer of dry filler. In addition, the quality of the fill of the dry particulate filler use water district fire-irrigation pipeline mine. As well as fill the dry particulate filler used foam obtained in the area of emergency fire area.

Given a set of features focused on the fact that the formed layer of dry filler in an isolated space with the cooling (water or inert foam insulated space) allows to form the barrier insulating jumper on the movement path of the fire gases with subsequent suppression of inert foam by displacing and reducing recharge of oxygen.

The drawing shows a conventional scheme disaster device to implement the method with partial longitudinal section.

A device for implementing the method comprises a transport platform 1 have been fitted with what tradigital 5 gear 6 and the actuator 7, installation suspension 8, connectors quick couplings 9, the inlet pipe 10 of the filing of the fill (water or foam) with a metering valve 11 with the connecting head 12 for connection to the source of the fill - fire district-irrigation pipe shaft (not shown), to the inlet pipe 10 is connected pocketmoney barrel-shaped nozzles 13 with the ejector 14 fence mine air fire atmosphere emergency site through the holes 15.

In the transport position, the platform has a base 16 for lifting the pipe 2 by the feed screw 3, the installation of the riser 17 and box 18 ZIP with pre-fabricated universal jumper and laying remote sections of the pipeline.

The invention is implemented as follows.

For isolation of emergency fire plot erect pre-fabricated universal jumper, connect the pipe 2 to the hopper 4 through the connection 9 type HRV and enter the output channel of the pipeline together with ploskostiam with nozzle-barrel 13 in an isolated space. Then fill the hopper 4 loose material such as fly-ash, cement and inert dust, powder, clay, etc., and through the inclusion of the electric motor 5 proceres inlet pipe 10 of the precinct fire-irrigation pipeline mine directly on pocketmoney barrel-shaped nozzles 13, additionally ejective fire air crash site by the ejector 14 through the built-in hole 15.

In order to reduce consumption insulation components instead of water supplied foam for volumetric filling of isolated fire and extinguishing it.

The invention provides effective fire fighting in the current emergency mine workings, reduces isolation and suppression of fire.
