The invention relates to mining, in particular to methods of construction of isolated hermetic mines, mines and pornobereich workings used for rescue operations, as well as for exploration and development of mineral deposits on space objects.

There is a method of construction of the trunk of advanced production Technology of underground construction. The construction of vertical openings. - M.: Nedra, 1992, str-240, RIS). The essence of this method consists in the following. Before the construction of the shaft in its Central part is an advanced formulation that is used for draining the rocks from the bottom of the barrel below the tunnel, which exploded breed loaded into trucks and transported to the dump.

The disadvantages of this method are:

- the cost to create a cutting-edge production;

- extension of the barrel is top-down, which limits its use;

- high complexity use in the construction of mines on space objects.

There is also known a method of construction of the mines and the mines on space objects (RU # 2368784, publ. 27.09.2009), including the construction of the main and auxiliary shafts drilling rigs from building shelters, installation germetezirujushie the insulating regiments.

The main disadvantages of this method are:

- the impossibility of carrying out rescue operations, which should be mandatory, and lack of ventilation in mines;

- long construction period of the auxiliary shafts;

- lack of communication on the surface of a space object between the trunks.

The objective of the proposed technical solution is the creation of a method of building mines on space objects, allowing to carry out rescue operations and to provide adequate ventilation in trunks and mines, as well as to reduce the cost and reduce construction time separate trunks, to establish communication between the trunks on the surface of the space object.

The task is solved by the proposed method of construction of mines on space objects, which includes the construction of the main and auxiliary shafts drilling rigs out of the building-shelter, at the mouths of the shafts sealing and insulating regiments. Differs from the closest technical solution that:

one of the auxiliary shafts are being constructed in the form of microstoma drilled exploratory well by extension, from the inner workings to the surface of a space object and used as a rescue shaft, is which on the surface through the lock chamber is in contact with the landing complex spacecraft, rescue shaft in place by its connection with the inner mountain development establish sealing insulation shelves, issue drilled rocks produced in the crater of a space object - this solution allows to conduct rescue operations in mines, as well as to reduce the cost and reduce construction time;

inside the rescue shaft move personnel using the appropriate hardware installed and plunged into the barrel, it also allows you to speed up the process of conducting rescue operations in mines;

rescue the trunk is used as an additional ventilation shaft using the appropriate equipment installed in the trunk or in the surrounding mines, allows to increase the safety of the works on the space object;

on the surface of a space object between the mouths of rescue and main trunks communicate in the form of mechanized road, allowing you to move cargo and personnel between the trunks.

The proposed solution is illustrated in the drawing, which shows the stage of construction of mines on the space object.

On the surface 1 a space object construct 2 main and auxiliary 3 trunks with SIP is using drilling rigs from building shelter 4. At the mouths of the shafts establish sealing and insulating the shelf 5. The main 2 and 3 auxiliary trunks inside of the space object are connected to the internal workings on the horizon 6. The auxiliary shaft 3 is converted into a rescue shaft (the drawing shows under the same position 3). For the construction of the rescue shaft 3 from the surface 1 a space object using drilling rigs are drilling exploration hole 7 provided in the chamber 8 on the horizon 6. Exploration well 7 can be performed in both vertical and inclined (as in the drawing) is associated with subsequent transformation into the rescue shaft, and an emergency exit on the surface of a space object in an inclined shaft will be longer, but it may be easier, and thus it is necessary to take into account the geological nature of this space object, the depth of the mine, the transverse dimensions of the shafts.

Rescue the barrel 3 being built in the form of microstoma, i.e. the minimum required in the transverse dimension (diameter) for a given mine or mine. Rescue the barrel 3 being constructed by drilling drill 9 exploration wells 7, with drilled rock down the shaft 3 in the cart 10 and is transported through the lock chamber into the crater of a space object next (not shown). Once uribana well 7 to the output shaft 3 to the surface 1 of the space object, where rescue the barrel 3 through the lock chamber 11 is in contact with the landing complex 12 spacecraft.

Rescue shaft 3 in the place of its connection with the inner mountain development 8 establish sealing insulation shelves 13, allowing in the case of an emergency at the mine or mine to completely isolate rescue the barrel 3 from the inner workings. Depending on the prevailing hydrogeological conditions at a particular space object instead of the proposed shelf 13 may apply airlock on the same spot of the barrel 3.

After the construction of the shaft 3 in its place the equipment to perform rescue operations in the mine, the mine (including for moving staff, or down inside the barrel of such equipment and other). To further address issues of mine ventilation, mine rescue shaft 3 place the equipment to ensure proper ventilation (pumps, valves, filters, etc., but adapted for a given space object), i.e. rescue the barrel 3 is used as an auxiliary ventilation shaft.

On the surface 1 a space object between the mouths rescue 3 and 2 main trunks communicate in the form of mechanized road 14, allowing goods to be moved and serving ersonal between the trunks.

When performing work on drilling exploratory wells 7 monitor drilled breed, and if you get the breed of interest, then they are selected and warehoused for future use.

The proposed solution allows for the construction of mines on space objects, allowing to carry out rescue operations and to provide adequate ventilation in mines, as well as to reduce the cost and reduce construction time separate trunks, to establish communication between the trunks on the surface of the space object.

1. The method of construction of mines on space objects, including the construction of the main and auxiliary shafts drilling rigs out of the building - shelter, at the mouths of the shafts sealing and insulating regiments, wherein one of the auxiliary shafts are being constructed in the form of microstoma drilled exploratory well by extension, from the inner workings to the surface of a space object and used as a rescue shaft, which on the surface through the lock chamber is in contact with the landing complex space ship, rescue the barrel in place by its connection with the inner mountain development establish sealing teploizolyatsii the traditional shelves, the issuance of drilled rocks produced in the crater of a space object.
