The latter are shifted relative to each other and connected to E 6. Mechanism 3 is made in the form of successively installed injectors 21 and a nozzle installed at its suction end. In E 1, C 2 is lowered; In E 6, water is supplied first and then compressed air. The air displaced by air from the E 6 enters the C 2 and through the nozzles installed on the bars 20 fills the E 1 by. set height. The compressed air, which then flows through the same nozzles in C 2 and E 1, mixes water with cement and sand, ensuring the production of the cement slurry.

The invention relates to mine construction and is intended for the preparation of cement slurries and the cementing of anchored space.

The aim of the invention is to improve the operability and reduce the loss of cement slurry.

FIG. 1 shows a device for cementing of the anchored space, general view; FIG. 2 shows a mixer, a general view; FIG. 3 is a view A. FIG. 2 | FIG. 4 shows the mechanism for dispensing the solution from the vessel; general view;

The tamponals fixation device consists of a tank 1 (figuratively rotated relative to the production), which may be, for example, a mine trolley, a mixer 2, a mechano-3m solution supply and a movable platform 4, which a winch 5 and an airtight container 6 are installed; Winch 5 is intended for raising and lowering mixer 2 into container 1 by means of a rope 7 of block 8 and a hook 9, Block 8 is attached to the top of the shaft support 10,

Mixer: 2 consists of several tubular sections 11, to which water and air are supplied to the section through pipes 12, 13, tank 14 and sleeve 15. At each section 11, in order to create a vortex flow of water and air in the tank 1, vertically axially at an angle of 60 to the vertical and on nozzles 16 are installed nozzles 17, 18, 19 displaced into sections in a vertical plane.

In order to adjust the inter-axial distance between sections 11, adjustable piping 20, for example screw-on, is articulated to pipes 12.

The mechanism 3 for supplying the prepared solution of capacity I consists of two or more successively installed injectors 21 of the same capacity, interconnected by means of a flexible sleeve 22, and a sleeve 23 intended to supply the solution to a fixed space limited from inside the mine working by mine puffs 24 , and outside - by the massif 25,

On the suction socket 26 of the receiving injector 21 with the help of partitions 27 rigidly attached to the socket 26, a nozzle 28 is installed, intended for the forced supply of the solution. The partitions 27 form a grid preventing solid particles from the tank 1 with dimensions exceeding the diameters of the internal openings of the injectors 21, the pipeline 29 and the sleeves 22 and 23,

The crane 30 serves to supply air to the injectors 21 through the tee 31 and the sleeves 32 and 33

Air is supplied to the nozzle 28 via the tee 34, the sleeve 35 and the tube 36, Pa. The nozzles 37 and 38 of the tank 6 are fitted with taps 39 and 40 for switching on the supply of water and air,

A steam tank 6 is fitted with a safety valve 41 for controlling an operating pressure in the tank

To the mixer 2, the supply of water and air is carried out along the sleeve 42 and is shut off by a valve 43.

The device works as follows.

The tank 1, loaded in layers with a dosed amount of sand and cement and underloaded to the height necessary to add a dosed volume of water, is brought to the bottom.

The mixer 2, suspended on the rope 7, is lowered into the tank I. With the tap 39 turned on, the tank 6 is filled with water in a predetermined volume. The crane 43 at the same time, is blocked. Then the opening of the valve 40 serves in the tank 6 compressed air.

The valve 43 is opened. The displaced compressed 20 fixed space with its air and water from the tank 6 through the sleeve 42 enters the mixer 2 and fills the tank 1 to a predetermined height through nozzles 17, 18 and 19. After all the water has accumulated from the tank 6, the valve 39 is closed and compressed air enters the mixer 2 through the same sleeve 42.

The compressed air jets emanating from the nozzles 17, J8, 19 ensure the mixing of water first with cement and then with sand, thus ensuring the production of a given cement slurry. After active mixing of the upper layers, the mixer 2 is lowered below until the bottom of the tank 1 is reached.

 After the ready solution is obtained, the receiving injector 21 with the nozzle 28 of the mechanism 3 is lowered into the tank 1

supply solution, and the sleeve 23 is brought into the closed space.

After switching on the crane 30, the compressed air flows through the sleeves 32, 33 to the injectors, and through the hose 35 to the nozzle 28, which ensures the forced supply of the solution to the socket 26 of the receiving injector 21.

In this way, the finished cement slurry is supplied.
