Description

 System | 20Q310728eF2iF oo. Mipiilliiiiiiiiiiii-ii - .. s. and C. s 0 T 2 u 9 isolation and extinguishing an underground fire

The utility model relates to mining and is used to localize and extinguish underground fires in hard-to-reach places.

A device for implementing the method is known, including an injection pipe into a fired area, an inert foam sump that has been prepared by 5-fold suspension of the foaming solution and liquid nitrogen, while mixing takes place directly in the fired area (ed. Certificate of the USSR No. 1286790, class E 21 F 5 / 00, 1985).

A disadvantage of the known device is the absence in its kit of a nitrogen-cladon installation with mixing units to produce foam of a combined phlegmatizing composition.

The prototype of the proposed technical solution of the utility model is the description of the certificate of the Russian Federation No. 25043.2002, which is described as a set of equipment for mechanization and safe isolation.

A disadvantage of the known utility model is the lack of a means of isolating a dead-end mine in the technological scheme of its implementation and the implementation of the method of extinguishing it by well-known combined techniques.

The purpose of the utility model is to increase the efficiency and safety of localization and extinguishing of underground fires in

inaccessible places by creating a combined phlegmatizing foam and its implementation through a pipe channel into an isolated space of a dead end mine.

 A block of spirals and connected to the tank and mounted on a rail transport platform1U at the equipment system, which additionally includes a platform for transporting containers with a foaming agent, flame retardant and filler, as well as a fire lance and a slurry submersible pump with an air drive and a foam mixer, while the evaporative block of underground gasifier spirals has a remote distribution manifold containing the functions of connecting peaks to remove snow formation from the evaporative block of spirals and with an evaporator of a transport discharge sleeve with an ejector mixer of freon for feeding it aerosol

the control tube of the jumper directly to the fogger in the isolated part of the mine, and the output part of the expanding part of the tuanogen is equipped with a foam rotor removable mesh.

The proposed set of distinctive X features provides through the introduction of an element of isolation and extinguishing a fire in a dead-end mining using combined phlegmatizing foam to increase the efficiency and safety of mine rescue operations in coal mines.

The figure shows the technological layout of the equipment system during a fire extinguishing directly in the dome and in the isolated part of the dead-end mining with the following reference designation of the technological equipment: 1 - block evaporative underground complex KAE-1; 2-peak air gun for removing snow formation; 3-fire-irrigation pipeline; 4.6.7 nitrogen gas supply hose; b-remote nitrogen gas collector; 8-jet ejector; E-sleeve supply of freon 114B 2; 10 dome; 11-fire peak; 12-ta control mine air: 13th jumper; 14-fogger (removable mesh) with remote tube; 15-isolated part of the output; 16- tee; 17- pressure head sleeve; 18 mixer; 1E-pump slarv1ovy submersible with pneumatic drive, ШПНП-2;

20-capacity with defoamer; 21.22 - containers with antipyrogen; 23efviKOCTb with a foaming agent; 24-sleeve connecting to the platform of liquid nitrogen tanks RCV-0.5 / 1.6 of the KAE-1 complex.

The system of isolation and extinguishing underground fires works as follows.

For extinguishing an underground fire in a mine

a temporary insulating jumper 13 is installed, in which a control tube 12 is provided for monitoring the mine air of the isolated space 15, and in our technological scheme for introducing a folding downhole fogger 14 through the tube to create and transport

combined phlegmatic aerosol freon in the emergency section of the isolated part of the mine. The isolating temporary jumper 13 is made by operation of a slurry submersible pump with pneumatic drive ШПНП-2 complete with additional technological equipment of the system. Extinguishing a fire in a mining dome 10 with a pump of type ШПНП-2 by means of a fire peak 11, mixer 18 and cladone 1146-2 21 is provided traditionally according to the well-known cxeiyie prototype according to testimony. No. 25043.

Removing snow formation after the operation cycle of the production evaporator 1 of the underground complex KAE-1 is carried out inside the winding of the spiral block, while peak 2 (pneumatic gun; is made in the form of a pneumatic gun with a nitrogen gas flow valve, which removes snow formation with a perforated peak gas and thereby increases the duration of work the evaporator 1 by supplying a combined phlegmatizing composition of containers 21 along the sleeve E through the mixer 8 along the discharge sleeve to the fogger 14 for dispersion and gasification freon aerosol in a satellite stream of gaseous nitrogen.

foam generator set from the fire-irrigation pipe line 3 a water supply hose is laid along with a foaming agent 23 and a cycle of work is carried out to pump the combined active foam plug into the isolated part of the mine 15.

The use of the proposed system of insulation and extinguishing fire with a combined phlegmatizing composition allows to increase the efficiency and safety of mine rescue operations in extremal conditions during the elimination of underground accidents in mines.
