The mixing and charging machine contains the following basic elements. On the chassis 29 of the base car, containers 1 are fixed for an emulsion matrix based on ammonium nitrate or ammonium nitrate in the form of granules (in the form of a stainless steel tank with thermal insulation, divided into five compartments forming containers for the emulsion matrix, ammonium nitrate granules (the purpose of the containers can change depending on the required composition of the emulsion explosive)). Also on the chassis 29 install the compartment 2 for the battery and the boxes 11 and 21

for tools for easy access when performing repairs. A container for water 3, a container 4 for an oil product, a container 10 for a gas generating additive, a container 12 for an EVE, a container 25 with fuel for an automobile chassis engine, a container 15 for hydraulic oil are also fixed on the chassis 29. The tank 15 for hydraulic oil is hydraulically connected to a hydraulic power take-off reducer (not shown conditionally) controlled by a hydraulic control panel 19. Capacity 1 (with ammonium nitrate in granules) is connected to a transporting feeder 6 of ammonium nitrate (a screw pump), an inclined feeder of 5 ammonium nitrate (a screw pump), and also a feeder of 7 ammonium nitrate. The tank 1 (its parts with an emulsion matrix) is hydraulically connected to the pump 8 of the emulsion matrix (screw or diaphragm), as well as a metering pump 9 for supplying the product (screw or diaphragm). The tank 4 for the petroleum product is hydraulically connected to the fuel pump 14 (gear or centrifugal). On the chassis 29, the drums 17 are mounted on racks with the possibility of rotation, with charging hoses connected through a valve 13 to switch the supply from one charging hose to another, combined with a water injector (used as lubricant for emulsion explosives in the hose). The charging hoses are connected in parallel with the metering pump 9 with the possibility of switching the supply from one hose to another using fittings 13 to switch the supply from one charging hose to another, controlled from the control panel 18. For the manufacture of special products, you can use cooler 16 (for example, for products of high viscosity type emulsion explosives). All shut-off valves and fittings can be controlled from the control panel 18.

A ladder 22 for climbing onto the tank 1 for the emulsion matrix is located between the cabin and the tank 1 for the emulsion matrix to increase the safety of the lift. On the tank 1 is provided a system 20 to prevent falling, which is a rising fence. On the chassis 29 there is a hitch 23 for the possibility of towing, for example, additional capacity with components of emulsion explosives. On the chassis 29, a wardrobe 24 is provided.

Above the cab chassis 29 and above the control panel 18, lights 29 for working lighting are installed to ensure comfortable work in the dark. Also on the chassis 29 are holders 27 for fire extinguishers in order to provide effective fire extinguishing means. To ensure comfortable work in sunny weather over the control panel 18 is mounted on hinges with the possibility of fixing the sun cover 28.

Mixing and charging machine operates as follows. Chassis 29 of the base car with the equipment and tanks installed on it is refueled at the plant for the production of explosive components. Next, the chassis 29 follows to the place of blasting, for example, to the site of the quarry. On the site of the quarry, the route of the chassis 29 is planned and the working area is outlined, after which the charging hoses from the reels 17 are unwound. The machine is put into production mode, the type of emulsion explosives produced is set on the control panel 18. The principle of preparation of emulsion explosives is to sensitize the emulsion matrix of emulsion explosives with gas bubbles by introducing into it a gas-generating additive (for example, sodium nitrite solution) and subsequent mixing with pre-oiled ammonium nitrate. The mixing-charging machine allows the sensitized emulsion to be fed into the well (using the emulsion matrix pump 8 and the product metering pump 9) and also oiled ammonium nitrate (using the feeder system - inclined feeder 5 ammonium nitrate, transport feeder 6 ammonium nitrate and feeder 7 ammonium nitrate. The ratio of components is maintained at a given level by the automatic dosing system (control panel 18, for example, in the form of a controller with software) or using hydraulic regulators controlled by rotameters and RPM sensors - in manual mode Control panel 18 controls the pumps necessary for the production of a particular emulsion explosive pump, delivering the required number of components: an inclined feeder 5 ammonium nitrate (for example, a screw pump), a transport feeder 5 ammonium nitrate (e.g., a screw pump), a feeder 7 of ammonium nitrate (e.g., a screw or screw pump), an emulsion matrix pump 8 (e.g., a screw or diaphragm pump), and also a metering pump 9 for supplying the product (for example, a screw or diaphragm pump).

Then, in accordance with the charging card, the wells are charged using both charging hoses alternately (or in parallel, depending on the design). Switching the supply from one charging hose to another is done from the control panel 18 using the fittings 13. By using two or more reels 17 with two or more charging hoses, the time losses associated with the downtime of the mixing-charging machine when moving the charging hose from one well are reduced to the other with a general increase in the productivity of loading wells. While one charging hose is being transferred, a second or third charging hose

used to supply emulsion explosives to another well. Next, the charging cycle is repeated until the emulsion explosive unit is fully charged.

The use of a mixing and charging machine provides the following advantages:

- increase the productivity of loading wells;

- increase the maneuverability of the machine;

- improvement of working conditions.
