The invention relates to mining works and can be used for open development of mineral deposits for transportation of rocks.

There is a method of transportation of rock mass, including a connection horizons rope, zapasovany on the winch located on the upper horizon, fixed to the rope capacity with the balloon, the loading capacity on the lower horizon portion of the rock mass and its movement from the bottom up, unloading and return of the vessel, the weight portions of the rock mass is equal to the free capacity of the balloon, and moving containers make the winch. (Patent RF №2052115, IPC 6 IS 41/26.)

The disadvantage of the invention is the low performance due to idling.

There is a method of transportation of rock mass, including the connection of the bearing horizons by flexible connections, fixed to flexible relations capacity with balloon can travel on them, unloading - loading capacity and its movement between the horizons, which was used for transportation establish flexible traction link between the vessel with balloon and other capacity with the balloon, and the unloading and loading is carried out on the upper and lower horizons to the sum of the lifting force of the lower balloon and weight of the cargo loaded on the upper horizon, exceeded the sum of the amount the lifting force of the upper balloon weight loaded on the lower horizon. (Patent RF №2114308, IPC 6 IS 41/26.)

This invention is selected as a prototype.

However, this method has limited use, it is implemented in a device with two parallel strained bearing flexible connections between the horizons, which are moving towards each other capacity with balloons. Flexible connections are sufficiently far from each other, because the balloons are of large dimensions, because only when large quantities of balloons you get a positive effect from their use. Balloons, if they are spherical, the diameter should be 50 meters. Taking into account wind effects on the balloon, the distance between the flexible connections shall be not less than 200 meters.

The present invention is the provision of transportation of rock mass from hard to reach places with narrow slopes, where to place the two-branches aerostatic design is almost impossible. In addition, to pave the way for the transportation of rock mass on the top and bottom horizons of the possible.

To achieve these objectives we propose a method of transportation of rock mass, including a connection horizons bearing flexible coupling, the attachment to the flexible connection of the containers with the possibility of free movement, the connection of the flexible containers traction link, equipped with the e balloon and loading of containers on the target horizons. Unloading of containers carried out at intermediate horizons, located between the stations of the boot upper and lower horizons. However, distances between stations, loading and unloading of each horizon are equal. Moreover, the balloon fixed to the capacity of the upper horizon and taking ore from the lower horizon with aerostatic force of the balloon, and the descent of the rock mass from the upper horizon with the gravitational forces of a moving mass of rock in the tank top horizon and empty the bottom of the vessel.

When lifting the rock mass from the lower horizon aerostatic force must be greater than the force of the moving mass is the weight of the bottom of the vessel with the cargo and the weight of the empty vessel of the upper horizon. And during the descent of the rock mass from the upper horizon of the gravitational force is the weight of the upper tank with the rocks and the lower weight of the empty vessel must be greater than the lifting force of the balloon. These conditions are ensured by the capacity of the tanks. The amount of the bottom of the tank must be less than the volume of the upper container.

The proposed invention solves the problem of transportation of rock mass from hard to reach places with narrow slopes.

The method allows to choose the appropriate intermediate horizons, located between the top and bottom, these horizons to organize the unloading station of the rock mass. And this is m horizons to pave roads for transportation of rock mass from the unloading stations to the consumer.

The application of the proposed method eliminates the disadvantages of the prototype and to transport minerals from hard to reach places.

Implementation of the proposed method is possible, for example, by using the device shown in the drawing. As the prototype used the device shown in patent No. 2114308, IPC 6 E21C 41/26.

The prototype includes two load-bearing rope stretched between horizons, forming two parallel cable car line. The lengths of the highways are equal. On each line attached to the vessel with balloon with a possibility of free movement on the supporting ropes. Capacitance connected between a traction rope, by which they are moved, the length of rope equal to the length of the lines, and when one of the tanks at some horizon the other tank is on the opposite horizon. During transportation of the rock mass should be observed ratio between gravitational and aerostatic forces the system to the sum of the lifting force of the lower balloon and weight of the cargo loaded on the upper horizon, exceeded the sum of the lifting force of the upper balloon and weight of the cargo loaded on the lower horizon.

A disadvantage of the known device is its complexity, i.e. when placing it occupies the most area on the side of the quarry, as well as the inability to use it in places with narrow slopes and do not have convenient access roads on the horizons.

The objective of the invention is to eliminate the above drawbacks of the prototype, i.e. the extension of the capabilities of the device by simplifying the design.

The problem is solved in that the device for implementing the method includes loading station and unloading of containers on the horizon, bearing a flexible connection between the upper and lower horizons, which is fixed to capacity with the possibility of free movement, interconnected flexible traction link, and a balloon. When this balloon is fixed to the vessel of the upper horizon and the unloading station of the rock mass located between the stations of the boot upper and lower horizons. However, distances between stations, loading and unloading of each horizon is equal to the weight capacity of the lower horizon with rocks and empty containers of the upper horizon is less than the lifting force of the balloon and the weight capacity of the upper horizon with rocks and empty containers of the lower horizon more lifting power of the balloon.

The drawing schematically shows the device in the projection on the wall of the open pit. The device comprises a container 1 with the balloon 2, the download location 3 upper horizon 4, capacity 5, the discharge place 6 on the intermediate horizon 7, the seat unloading 8 on the intermediate horizon 9, download location 10 on the lower horizon 11, carrying the rope 12, the flexible traction link 13, the attachment carrying a rope 14 and 15.

The device operates as follows: vessel 1 with the balloon 2 are on the download location 3 upper horizon 4, and the container 5 at the discharge place 6 on the intermediate horizon 7. After loading the container 1 and the discharge capacity 5 rastormazivate them, and they begin to move. Tank 1 will be located at the discharge place 8 on the horizon 9, and volume 5 will take a position on the loading area 10 on the horizon 11. The whole system moves under the action of gravitational forces on an inclined bearing rope 12. Upon reaching their stations capacity is automatically decelerated and when loading and unloading do not move. After loading capacity 5 and the discharge capacity 1 device restoratives, and under the action of aerostatic force of the balloon 2 containers are returned to their initial positions. Capacity 5 capacity less capacity 1. This provides automatic transfer system of tanks and balloon up and down due to gravitational and aerostatic forces the device without the involvement of external energy. In the drawing the letter "a" denotes a distance from the lower and upper horizons to the discharge transport horizons.

The proposed device is simple in construction and can be placed on narrow slopes and through the use of gravitational and aerostatic forces to the minimum decrease in the energy cost of haulage and thus achieved a significant positive effect
