Description

The utility model relates to the mining industry and can be used for the selective extraction of long mineral faces with the laying of rock in the worked out lava space, including in the mines of the Starobinsky potassium salt deposit.

Known devices for overloading rock mass in lavas during selective excavation [1]. The device includes a combine harvester for selective excavation, a face conveyor, filling stations located on the side drifts and in the middle of the lava. To deliver the rock to the filling stations between the combine road and the supports, the filling conveyor is located with unloading windows in the places of acceptance parts of the filling installations, to which a mobile transfer station is carried out for loading the rock from the downhole conveyor on the side drift.

A disadvantage of the analogue is a significant complication of the design of the device due to the installation in the lava of an additional filling conveyor for the delivery of filling material (rock).

The closest in technical essence to the claimed utility model is, selected as a prototype, a device for overloading rock mass in lavas [2]. The device is made in the form of a face conveyor, in which there is a special hatch (discharge window) at the installation sites in the lava of the filling device, which can be closed and opened using a special valve (gate) with a hydraulic jack. At the location of the hatch, a filling conveyor (reloader) is installed, which directs the filling material to the thrower. For its installation under the head of the downhole conveyor pass a special drift with a disruption relative to the lava soil. When transporting minerals, the hatch closes and it is delivered to the conveyor belt and further to the surface. When removing rock layers in the face conveyor, the hatch opens and the rock enters the filling conveyor and further to the thrower.

The disadvantage of the prototype is the high cost of organizing the overload of rock mass in the lava due to the need for additional drifts with soil undermining relative to the lava soil for installing a filling loader under the hatch of the downhole conveyor, as well as increased volumes of rock discharged to the surface during the preparation of the site for selective excavation (additional dilution ore).

The objective of the utility model is to improve the quality of ore, reduce the cost of preparing the site for selective excavation.

The solution to this problem is achieved by the fact that the device for reloading the rock mass in the lava, including the filling conveyor and the downhole conveyor, equipped with a discharge window with a valve, becoming the downhole conveyor at the location of the filling conveyor is installed on skis, the height of which is sufficient to be placed at the location of the discharge window downhole conveyor of the working branch of the loading part of the filling conveyor, made with a horizontally closed traction body, while the downhole ski is made in the idea of a loading ploughshare, and a dumped plow with openings for the staves of the filling conveyor.

Figure 1 shows a device for reloading rock mass in the lava (top view), the drive and tail parts of the downhole and filling conveyors are not conventionally shown; figure 2 is a section aa in figure 1; figure 3 is a view of B in figure 1.

A device for reloading the rock mass in the lava consists of a filling conveyor 1 and a downhole conveyor 2.

The filling conveyor 1 is made with a horizontally closed traction unit, consisting of a single sprocket 3, a drive sprocket 4 and a closed chain 5 with scrapers 6. The drive 7 of the filling conveyor is located on the discharge part of the conveyor, which provides loading of the rock mass into the receiving part of the thrower 8.

The downhole conveyor 2 consists of a tackle stand 9 with a traction chain and pans, attachments 10, head and tail drives (not shown in FIG.). In the location of the filling conveyor 1, skis are installed: downhole 11 and zavalnaya 12. Downhole ski 11 is made in the form of a ploughshare and provides loading of minerals on the downhole conveyor 2, protection against getting it on the filling conveyor 1, moving the support-guide mechanism of the shearer in place overload. Zavalnaya ski 12 is made with openings to accommodate two branches of the stav zavalnogo conveyor and serves as a support for the supporting-guide mechanism of the shearer.

Both skis are made with a height that is sufficient to accommodate the boot conveyor 2 of the filling conveyor 1 under the bottomhole conveyor.

In the downhole conveyor 2 in place of the working branch of the loading part of the filling conveyor 1, discharge windows 13 are made, which can be closed by a valve 14 using a jack 15.

The device operates as follows.

Mineral destructible in the face is loaded by a shearer to the face conveyor 2 and delivered for subsequent transportation to the side drift. When this unloading window 13 is closed by a valve 14.

When carrying out filling operations, the rock mass (rock) that is destroyed in the face by a shearer is loaded onto the face conveyor and sent to the discharge windows 13, which are opened by a valve 14 with a jack 15. The rock mass enters the discharge part of the filling conveyor 1 and is unloaded into the throwing unit 8.

If necessary, several devices for overloading the rock mass can be installed in the lava.

Thus, the proposed device can be repeatedly used in the development of lava deposits of potash salts, for example, Starobinsky, with the technical result, which consists in improving the quality of ore and reducing the cost of preparing the site for selective excavation.
