Abstract

The invention relates to a mining transport, increases reliability and reduces the energy intensity of the complex. For this cargo and empty yields 1, 2 have oppositely directed inclines. Their value is determined by the required water velocity in the trays of workings 1, 2. The latter are connected by field loading output 3 and a slope. When water is supplied by the water-lifting station 13 to the upper trays, a speed flow is established involving the movement of the container conveyor. At loading capacity 3, containers are loaded with ore and delivered to the discharge slope by a stream of water. The latter is used to unload containers by means of an unloading means installed therein. It is made, for example, in the form of a rotary drum with guide rollers placed in its cavity under containers. I zp f-ly, 7 ill. (L 00yo 00 SP JV 05 sri.

Description

This invention relates to mining transport.

The aim of the invention is to increase the reliability and reduce the energy intensity of the complex.

FIG. 1 shows a diagram of the transport complex in plan; in fig. 2 is a diagram with intermediate water lifts in conditions of especially extended workings; in fig. 3 - tray, vertical section; in fig. 4 is a section A-A in FIG. 3; in fig. 5 - discharge means, vertical section; in fig. 6 is a section BB in FIG. five; in fig. 7 is a sectional view BB in FIG. five.

The transport complex includes cargo 1, empty 2 and field loading 3 yields with adjacent orth 4 and ore lances 5. Cargo and empty yields have oppositely directed slopes, the magnitude of which is determined by the required speed of water in the trays 6 and the container conveyor that consists of floating containers 7, coupled with flexible couplings 8. Trays 6 can be lined with antifriction material 9. Trays are mounted in trays, traversed in the soil workings inside the track of self-propelled mining machines n 10 with the required clearance between the conveyor and the chassis.

In the area of the mine ore, mines 1 and 2 have different elevations, differing by 20-25 meters or more. To close the conveyor chain, these openings are connected by a slope 11, which is simultaneously used for unloading containers. On slope 11, various types of unloading means 12 for containers may be provided.

At the junction of cargo production 1 to slope 11, a water-lifting station 13 is arranged with transfer pipeline 14, which connects hydraulically the production trays 1 with the production trays 2.

In the same area, a mine water collector 15 is constructed with a pumping station of the main drainage system 16 for pumping mine water debit through the shaft 17 to the surface.

Slope 11 is connected to a capacitive bunker 18, equipped in the lower part with a feeder 19, loading the ore into the mine hoist 20.

In specially mined workings 1 and 2, in order to reduce the difference in their heights, intermediate slopes 11 may be provided, equipped with lifts 21. The lower junction of transport output with a slope is equipped with a lifting station 13 and an accumulator water collector 22 in case of a temporary shutdown of the pumps of lifting stations 13.

The discharge slope 11 is equipped with discharge means consisting, for example, of a large drum 23, equipped in its cavity with guide rollers 24 under containers 7. The drum 23 is placed in outwardly located supporting rollers 25 and stop rollers 26 and is connected to the drive 27, for example a gear 5 chain drive 28. In the drum 23 or in front of it on the rollers 29 there is mounted a freely rotary snare drum 30, also equipped with directional rollers 31 according to the configuration of the container 7. On

 Out of the tray 6 to the drum 30, fixed containers 32 for containers can be mounted on the slope. The drum 30 has an eccentricity of mass, which in its free position rotates it to its original position for the entry of a new 5 container.

The transport complex works as follows.

When water is supplied by a water-lifting station 13 to the upper trays 6, it sets 0

with a high-speed stream of water involving

in motion container conveyor. At the loading exit 3, the containers 7 are loaded with ore and then, with a stream of water, are delivered to the discharge slope 11.

5 Each container 7 enters the rollers 32 and 31 into the snare 30 in the transport position, while the preceding containers make circular turns in the large drum 23 in the rollers 24 with the material unloaded inside the drum 23.

0 Rolling material on slope

its inner surface during rotation creates a continuous vibration of the walls of the drum, transmitted to the containers 7, which helps to complete unloading and cleaning of their bodies from adhering material. Drum can

5 to have a length corresponding to several turns of each container when passing them on a slope for the purpose of high-quality cleaning. From the drum 23, the material enters the capacitive bunker 18 and then through the feeder 19 into the mine lifter 20.

 The rotation of the drum 23 is synchronized with the speed of movement of the containers 7 in such a way that when leaving the snare drum 30 the rollers 24 occupy a position in the configuration of the section of the new container

the latter enters the first row of rollers 24. The rollers 24 force the container 7 to begin tilting along with the snare 30. The container can be unloaded only when it is completely out of the snare 30, after which the latter automatically tilts back to its original position from it, the container is discharged inside the drum 23. Both the discharge and intermediate slopes can be equipped with mechanical slide lifts for the containers with empty rollers. Movement through them can be achieved by pulling the hitch from the container chain, which is involved in a high-speed flow of water behind the slope.

The use of the invention will improve the reliability of a high-performance conveyor by eliminating multiple drives. The transport system with energy carrier in the form of mine water is associated with mine drainage.
