Abstract

The invention relates to mining and is intended for plow units in the extraction of coal by the underground method. The goal is to increase the efficiency of excavation by reducing the cross-section of previously carried out workings and reducing the cost of maintaining them. The unit includes mechanized lining sections 1, associated with a lateral conveyor 2, lining mating, a multi-axis actuator with plow carriages 13, drives 6 with shafts 5 and driving stars 8, loading device and end heads (KG) 15 with shafts 22. Each KG consists of a logger 16, a breakaway rod 17 with buckets, a protective shield (U) 20, a segment housing and a telescopic support 24. The shaft 22 is mounted on the support 24 coaxially with the shaft 5 and connected with it by a coupling 23. The support 24 is designed as hydraulic cylinders hinged on skis 26. Kaj th ut 20 is a disk whose diameter is equal to the length of rod 17. One ut 20 is formed with a window for the passage of minerals. The segmental casing on the side of the transport working is made with a loading window and is connected to the loading crane via a tray. The ends of the lava are treated with CG. Replaced by the CG, the mineral at the transport selection is loaded with buckets through the loading window onto the tray, and at the ventilation section with the toe onto the conveyor 2. The rest of the lava is processed with plow carriages 13. 5 Il.

Description

lindrov, shariirno fixed on skis 26. Each U 20 is made in the form of a disk, the diameter of which is equal to the length of the rod 17. One of the U 20 is made with a window for the passage of the mineral. The segmental casing on the side of the transport working is made with a loading window and is connected to the loading crane via a tray. The ends of the lava are treated with CG. Replaced by the CG, the mineral from transport production is loaded with buckets through the loading window onto the chute, and at the ventilation one - with the toe to the conveyor 2. The remaining part of the lava is processed by the carriage 13. 13. Il.

The invention relates to mining, namely to plow assemblies for the extraction of coal by underground mining.

The purpose of the invention is to increase the efficiency of excavation by reducing the cross-section of previously carried out workings and reducing the cost of maintaining them.

Fig. 1 shows the frontal cleaning unit, view from the side of ventilation generation; figure 2 is the same, the view from the side of transnortnoy production; FIG. 3 is a view A of FIG. in fig. 4 is a view B in FIG. 2; in fig. 5 is a section on BB in FIG.

The front cleaning unit consists of sections 1 of mechanized roof support associated with a face conveyor 2, an annular multi-circle actuator body 3, on drive shafts 4 and 5 of drive 6 and 7 of which drive stars 8 and 9 are mounted. Support 10 and I 1 conjugation housed, in adjacent areas.

The Mud-circular Executive Or-1 3 consists of a vertical chain 12 closed in a vertical plane, plow carriages 13 and end heads 14 and 15 pushed forward, extending in places of junction with lava with workings.

Barriers 20 and 21 are installed between the planes of movement of the fender rods 17 and the turning planes of the plow carriages 13, preventing the plots of the plow carriages 13 from falling into the rock mass destroyed by the end heads 14 and 15. Barriers 20 and 2 are made in the form of discs 27 and 28, the diameter of which is equal to the length of the breakaway bar 17. On the side of the workings along the ends of the disks 27 and 28, the protective shields 20 and 21 have segment housings 29 and 30. Segmental casing 30 of the protective shield 21 located on the side of the transport making has ruzochnoe window 31 associated with tray 32 loader 33.

The disk 27 of the protective shield 20, located on the side of the ventilation openings, has a window for the passage of a broken mass of minerals on the side opposite to the ventilation openings.

Buckets 18 are made without an internal end wall on the side of the disk 27, which provides unloading of minerals in front of the toe 34 of the face conveyor 2, and buckets 19 - without a wall on the side of the segment segment 30, which ensures unloading of the bucket into the loading window 31.

Frontal cleaning unit works as follows.

The in-diggers 16 and the bogie bars 17 process the face at the edges of the lava, expanding the adjacent workings. The mineral resource they beat off is loaded from the side of transport making by buckets 19 through loading window 31 to tray 32 and further to material handling crane 33., and from the side of ventilation making by buckets 18 to soil in front of toe 34 of the face conveyor 2 and then toe 34 to conveyor 2.

The rest of the bottom is processed by plow carriages 13. When

one

By this, the direction of movement of the lower branch of the traction chain 12 coincides with the direction of movement of the load branch of the face conveyor 2, which ensures the unloading of the mineral resource, broken off by the end heads 14 and 15
