The invention relates to methods of preventing fires in places of occurrence of peat or other prone to fire the compressed loose easily flammable materials, such as deposits of waste pulp and paper industry.

The need to develop effective means and methods of fire prevention, especially hidden fires in terms of natural landscapes over large areas is an important task. The urgency of this problem is due to a significant injury to human health, undermine natural resources, economic losses associated with the extinguishing of such fire, in which people die. It is very important circumstance is the creation of ways to prevent fires that meet the requirements of Geoecology.

To extinguish fires in peatland provides some methods that can be used to prevent fire. Such methods include a method of extinguishing water supplied to places where fire through the needle trunks or other pipelines and moisturizing peatlands (Povsic YS, Clusaz P.P., Matacin A.M. Fire tactics., M.: stroiizdat, 1990, s.312-314).

The disadvantages of this method is low efficiency due to the fact that the supplied water is drained to a depth that requires a constant supply of water is. At the same time it is impossible to arrange the water supply to the entire area of peatland, given its size and obstruction of places.

For the prototype accepted way of limiting the spread of fire in peatlands by digging hearth possible ignition of the ditch, which is filled with water (Povsic AS, Clusaz P.P., Matacin A.M. Fire tactics M.: stroiizdat, 1990, s)that provides hydration peatlands, and may reduce the likelihood of fire.

The gasket channel around the hearth and flow in the water channel - characteristics of the prototype, coinciding with the essential features of the claimed invention.

The disadvantage of the prototype is low efficiency due to the fact that water from ditches constantly seeps in deeper horizons, not providing a wetting layer of peat, while it is impossible to manufacture ditches throughout the area of peatlands, a substantial area of peat deposits and the presence of impassable places. In addition, it will require substantial costs to maintain sufficient for effective wetting of peat, constantly declining water level.

The invention is aimed at improving the efficiency of prevention of fire in peatlands due to more efficient wetting of peat and reduce the cost of carrying out works for the prevention of fire.

Technical results of the claimed invention is to create an ecosystem of natural resources, able to withstand a possible fire hearth due to spontaneous, prolonged and more intense impregnation peat water around the fire as the increased likelihood of a fire hearth melting extensive network of ice arrays.

The delivered result is achieved that in the winter pave the channels around the center potential fire and must be prepared in the channels and the natural recesses of ice massifs through the feed water in them in the winter.

The delivered result is achieved by the fact that ice massifs after numerazione covered with insulating material, which is used as a layer of soil or peat mass.

The delivered result is achieved by the fact that the frosting lead water originating from the subsurface horizons of the places of occurrence of peatlands.

The contrast of the prototype is the lining of ditches around the center of a possible fire in the winter and frosting in the prepared channels and the natural recesses of ice arrays through water in them in the winter, which proves the compliance of the claimed invention, the criterion of "novelty".

Novel features of the invention provide effective wetting peatland throughout the area, on which the who is one fire, moreover, the mode of impregnation, that is, the number allocated to the soaking water, is determined by the temperature inside array of the peatland. The temperature of the peat bog is directly related to temperature and process within the peatland, for example, a possible flashpoint. The temperature rise of the peat bog provides a more active ice melting, more abundant wetting of peat and suppression of inflammation.

The effectiveness of the proposed method will be higher also due to the fact that the preparation of the channels and the freezing of the ice pack according to the invention are produced in winter, when there is an opportunity to move over the entire area of the peatland and create an extensive network of canals, and also available on the entire area of peatland natural cavities, such as craters from earlier fires.

To reduce the rate of melting of the glacier due to the heating of air and exposure to the sun ice massifs covered with insulating material, namely a material obtained in the manufacture of the channel, i.e. soil and peat mass.

Improving the efficiency of the method and reducing the cost of measures to prevent fire will be greatest if numerazione ice arrays to use water, which is typically the under layers of peat or deeper underground th is Sontag, eliminating the need to transport water transport or pipeline.

Thus, in accordance with the proposed method is able to utilize the available natural resources to create an ecosystem that can withstand a possible fire. This system is created from the existing peat materials without attraction of additional financial resources. In addition, the proposed method fully meets the requirements of Geoecology, which also increases its efficiency, because you will not need tools to eliminate possible contamination of the natural environment.

You know the frosting frozen arrays when crossing bodies of water if they are not thick natural ice.

It is also known the use of ice arrays for lowering the temperature when storing food in the summer.

In the inventive method, the freezing of ice massifs around the center possible ignition when the temperature provides a prolonged mode of impregnation of peatlands as glaciers melt, i.e. implements a different function of glaciers in comparison with the known examples of the application of ice arrays, and it is to prevent fire is used primarily water - product of the melting of the glacier, and not the ice, for the effective implementation of the FPIC of the BA prevent fire implements the appropriate mode glacier melts with increasing temperature in the peat bog.

Comparative analysis shows that the prior art does not follow the evidence of the proposed technical solution, which proves the conformity of the proposed method the criterion of "inventive step".

The way to prevent a fire in peatlands is implemented as follows.

In the winter, when you can move through the peat excavation equipment, produced manufacturing channels according to certain schemes covering the pockets of possible ignition. After that, the prepared canals supplied water and the freezing of ice massifs in the channels and the available natural cavities by irrigation. When freezing ice arrays would be more effective to prevent a possible fire, if the top edge of the arrays will be at the level of the surface of the peatland or somewhat higher, which will impregnate the peat from the upper to the lower layers.

Water supply for numerazione ice arrays can be produced from underground aquifers located directly underneath the peat bogs at low depth. The rise of water can occur through drilled wells or wells.

To protect massifs of ice from melting under the action of direct sunlight, they should be covered with insulating material, in which COI the box is used the soil or peat mass, extracted in the manufacture of the channels.

Thus, addresses the important task to reduce the likelihood of fire in peatland or deposits of waste pulp and paper and other industries, prone to fire, using available resources and compliance Geoecology.
