The invention relates to the field of technology of creation of underground chambers or storage in the earth's crust and can be used in the energy sector for the storage of liquid or gaseous fuel or to use geothermal energy to injection into a water reservoir.

The problem consists in the following.

Russia is a huge country, the reserves of mineral resources is also very high. The distance from the settlements to the developed mineral deposits are large. In particular, the Ural is a region with a harsh climate, where the temperature ranges from minus 50°C to +40°C. Large distances between settlements create difficulties in ensuring their electricity and gas. Constantly laying gas lines, power lines, construction of gas boilers. Currently, housing and communal services are reconstructed old fuel oil and diesel boilers. Despite this, in rural areas there is constantly a lack of heat, electricity is supplied irregularly. The tariffs of natural monopolies and housing services are constantly growing. Operation of engineering networks annually allocates huge funds. The distance from the energy resources makes it impossible for the construction of small and medium enterprises.

For the mining is yuusha enterprises, remote communities, seaports, military units, for all industrial and polar Urals have Autonomous supply of electricity and heat. The most promising in such circumstances is the use of geo - and solar thermal methods of electricity generation, the use of geothermal heat. For the latter, in the absence of natural underground cavities it is necessary to ensure the construction of the underground chambers.

Construction of underground chambers may be effected by explosive drilling or nuclear explosions.

Thus, the known method explosive drilling, developed by the group of companies "Semirechye" and described on the website www.semireche.ru 2009

Known for explosive drilling is in continuous processing bottom-hole small charges of explosive substances, introduced into the flow of the flushing agent (air or liquid) in the form of ampoules (ampoule or cartridge vzryvoobrazny) or continuous jet (jet blast drilling). Charges capsules are streamlined and safe to use, as the mixture of explosives) is right at the bottom.

Charges of solid EXPLOSIVES require to Bang large impact velocities (not less than 80 m/sec). When the jet vzryvoobraznyj explosive mixture of combustible oxidizer in the form of a flat liquid charge is brasaetsa directly on the face and activates a eutectic mixture of potassium and sodium, injected with a certain frequency. Vzryvoobrazny wells can improve drilling performance by 2-5 times. The disadvantage of this method is that it is used only for drilling vertical wells to 1.5 km. Similar way to the explosive drilling also described in the book Ugolnikov VK "Physics of rock failure when blasting", Magnitogorsk, 2005

There is a method of construction of an underground repository in compressible soils, described in the same application No. 93008095, CL E21D 13/00, E21F 17/16, B65G 5/00, P/10/02, Z. 10.02.93, op. 27.11.95 and selected as a prototype.

The known method involves drilling vertical wells, placing them in postilochnyh charges of explosives (e) and stemming from the crimping mixtures, the formation of the charger and the compensation cavities by detonation of explosive charges, while drilling the required number of vertical wells provide at least 120 radii prostrelennoe charge W and not more than 2Rewhere Reis the radius of the zone of efficient use of energy explosion of the main charge W on the compensation cavity, and Re=(0,65-0,7)×√v/n where V is the design capacity of the underground storage, n is the number of paired tanks in the store.

In vertical wells placed prostredie charges W and stemming from Nepalese mixture is with a coagulant, which is done by the method of inverse emulsion containing oil, latex, clay and aggressive water. By explosion postilochnyh charges form extra long charging the cavity with fortified walls, in which are placed the main charge and the stemming of defacements cement mixture with the accelerator setting. The height of the layer defacements mixture is equal to 2R.

Sequential blasting of the main charges in two neighboring wells form a conjugate underground storage tanks with walls, fixed solid waterproof coating. Similarly, carry out sequential blasting of the main charges in the remaining wells.

The method allows to significantly increase the efficiency of blasting and reduce the complexity of the construction of underground repositories through the use of compensatory cavity of the storage tanks, as well as due to the formation of coatings of the walls directly in the process of blasting.

A disadvantage of the known technical solution is the complexity of its implementation, due to the need of drilling multiple wells, as well as the fact that this method is typically used for smaller drilling.

The goal is to simplify the technology for underground cavity at great depths.

Set the military task is solved by in the method of construction of an underground repository in rocky soil, namely, that are drilling multiple wells, place them in prostredie charges of explosives, use the basic charge and the stemming, blowing the main charges form an underground cavity, CHARACTERIZED in that the vertical trunks wells are drilled by any of the known methods to a depth of 3-5 km, as part of them counter-inclined, converging to a single point on the depth, and use them as input, selecting the angles such as to exclude spontaneous explosion, and then produce a casing of these sites trunks pipes, in which take as postilochnyh and fixed charges all charges balls of solid explosive shells interspersed with the initiators of the explosion, and electronic devices for signal reception to undermine, placing them into the pipe and simultaneously feeding in tubes of liquid explosives, then give the signal for the explosion, then control using seismic boundaries formed in the explosion at a depth of 3-5 km underground cavities and drill to the beginning and the end of approximately one point sloping diverging wells for subsequent use.

Execution part drilled by any known method to a depth of 3-5 km wells inclined with ug is AMI tilt, excluding spontaneous explosion and converging to a common point in conjunction with the casing obtained trunks pipes and feed them postilochnyh and the main round of charges from solid explosives fed into the input wells simultaneously with liquid explosive mixed with initiators of the explosion and managed by the electronic device provides the ability to get the tilt-horizontal cavity at a depth of 3-5 km, subsequent monitoring using seismic boundaries formed in the explosion at a depth of 3-5 km underground cavity in conjunction with the drilling to the beginning and the end of approximately one point on the earth's surface inclined diverging to the ends of the cavity wells provides the possibility of further targeted use the resulting underground cavities. The technical result is an easier way to get underground cavities in rocky soil at great depths.

The inventive method has the novelty in comparison with the prototype, differing from it in such essential characteristics as drilling vertical boreholes by any of the known methods to a depth of 3-5 km, some of them counter-inclined, converging to a single point at depth, using them as input, selection for drilling angles such as to exclude from morosely explosion, the implementation of these casing sections trunks pipes, feed them as postilochnyh and the main round of the charge - balls of solid explosive shells interspersed with the initiators of the explosion, and electronic devices for signal reception to undermine, lowering them into the pipe with simultaneous flow in tubes of liquid explosives, the subsequent signal for explosion control after the explosion using seismic boundaries formed in the explosion at a depth of 3-5 km underground cavity, drilling to the beginning and the end of approximately one point inclined diverging to the ends of the cavity wells for subsequent use of the resulting cavity, providing collectively achieve the specified result.

The applicant did not know the technical solutions with these distinctive features, which collectively achieve the specified result, he felt, therefore, that the proposed solution meets the criterion of "inventive step".

The inventive method can be widely used in the technology of creation of underground cavities cameras, and therefore meets the criterion of "industrial applicability".

The invention is illustrated in the drawing, which shows a diagram of drilling.

The inventive method consists in the following. Buryats any of f the th methods several vertical wells to a depth of 3-5 km Some of these wells 1 and 2 perform sloping, converging at a depth of 3-5 km approximately to a single point and use them as input. The angle of inclination of these wells chosen so as to exclude the possibility of spontaneous explosion. Perform the casing sections of the trunks of these wells pipes 3, serves them prostredie and basic charges 4, as postilochnyh and basic use charges all charges 4 of the solid explosive shells interspersed with initiators 5 explosion, and electronic device 6 for reception of a signal to undermine. At the same time with them in the well served liquid explosives 7. Served using electronic devices 6 signal disruption. After the explosion is determined using seismic 8 boundaries formed underground cavities and drill about from one point to the edges of two sloping diverging deep wells 9 and 10 for purposeful use.

The inventive method is carried out as follows.

Multiple input deviated wells 1 and 2 Buryats, in particular, rotary manner to a depth of 3-5 km, selecting the angles so as to eliminate further spontaneous explosion in the delivery camouflage explosives. In the area of sedimentary rocks produce a casing of these sites is tolow steel pipe 3. Then at the mouth of wells 1 and 2 omit all charges 4 of solid explosives in the shell, for example, of rubber or plastics, protects against spontaneous explosion in the heat of friction and downhole shock when moving down. It focuses charge, the nature of the actions - dispersed charge, and the nature of the actions - camouflage.

Charges have 4 evenly interspersed with initiators 5 explosion and receiving the signal by the electronic device 6. For "soft" delivery of solid explosives, excluding uncontrolled explosion, between "balls" pumped liquid explosives 7, which reduce the shock pulses and temperature effects. Liquid explosives 7 for initiating explosion fills the cavity of the charge, thereby reinforcing the power of the explosion, increase shock wave to form a large area of destruction equal to 100 diameters of the borehole. After education in the explosion of an underground cavity 11 with the help of seismic sensors 8 detect the location of the edges of the cavity and with the earth's surface about from one point to the edges of the cavity are drilling two sloping diverging deep wells 9 and 10 for subsequent use of this cavity 11.

In this way there is formed an inclined-horizontal heat transfer is th tremenously underground Luggage storage between input and output shafts wells.

In comparison with the prototype of the proposed method of construction of an underground repository in rocky soil is simpler.

The method of construction of an underground repository in rocky soil, namely, that are drilling multiple wells, place them in prostredie charges of explosives, use the basic charge and the stemming, blowing the main charges form an underground cavity, characterized in that the vertical well holes Buryats any of the known methods to a depth of 3-5 km, as part of them counter-inclined, converging around one point on the depth, and use them as input, selecting the angles such as to exclude spontaneous explosion, and then produce a casing of these sites trunks pipes that deliver as postilochnyh and fixed charges all charges balls of solid explosive shells interspersed with the initiators of the explosion, and electronic devices for signal reception to undermine, placing them into the pipe and simultaneously feeding in tubes of liquid explosives, then give the signal for the explosion, then control using seismic boundaries formed in the explosion at a depth of 3-5 km underground cavities and drill to the beginning and the end of approximately one point sloping diverging wells for p the next use.
