Abstract

The invention relates to mining technology, and more specifically to the means of mechanization of the processes of carrying out and fastening of rising workings. The goal is to increase the safety of work and increase the rate of penetration in irregularly shaped workings by reducing the labor intensity of lining assembly. The shelves include a working platform 1, under which the winch 2 is placed. With the uprights (C) 4, the working platform 1 is connected to the support crown 5. The latter is made in the form of a frame consisting of upper and lower rims 6 and 7 respectively. With 8 placed on one side, a slider 9 is located with a block 10 and a gripper 11 for interacting with the support. On the C 8, located on the other hand, movable stops 14 are installed for periodic interaction with the lining. In the working platform 1, there is an opening closed by lane 16. The upper and lower rims 6 and 7 center the shelves in the excavation and form a kind of jig in which the support rings are assembled from tubings. The upper rim 6, having a diameter larger than the diameter of the support rings, eliminates the possibility of the shelf falling down and protects the upper support ring from collapse during the explosion of explosive charges. From the winch 2, the rope passes through the block 10, the sleeve and is fixed on the skip 13. 7 sludge.

The invention relates to the mining technique, and more specifically to the means of mechanization of the processes of carrying out and fastening the rising progress of

The aim of the invention is to increase the safety of work and increase the speed of penetration in irregularly shaped workings by reducing the labor intensity of the lining assembly.

Fig 1 shows the shelves, a general view; in fig. 2 - a slider with a block and stop; in fig. 3 - shelves, top view; in fig. 4 - 7 - schemes of work of the locus.

The shelves have a working platform 1, under which a winch 2 with a rope 3 is placed. With racks 4, the working platform is connected to a support ring 5, which has an upper outer rim 6 and a lower inner rim 7, Rims 6 and 7 are connected by racks 8, on two located with one On the side of the uprights, there is a slider 9 with a block 10 and a catch 11 for interacting with the support. The rope 3 from the winch 2 is passed through the block 10, the sleeve 12 and is fixed on the skip 13. On the two diametrically opposed pillars 8 there are movable stops 14 for periodic interaction with the support. A rope ladder 15 is attached to the lower rim 7. In the working platform 1, there is an aperture closed by the folding hole 16.

The upper outer 6 and lower inner 7 rims center the shelves in the excavation and form a kind of jig in which the support rings are assembled from tubing 17. In addition, the upper rim 6, having a diameter larger than the diameter of the support rings, eliminates the possibility of the shelf falling down and protects the upper ring in support from collapse in the explosion of explosives.

When coal mining is carried out using a shelf, it can be excavated using

tray or drilling and blasting works from the Order of performance of work following 1VDY.

At the beginning of the cycle (Fig. 4) of the shelves, the upper outer rim 6 rests on the upper edge of the support ring, the slider 9 with the block 10 and the grip 11 is in the upper position and the grip 11 also rests on the upper

the lining edge, and skip 13 is lowered into the lower drift. At this position, the shelf is dredging coal. When the coal is dredged with a jackhammer, after the bottom is advanced by an amount multiple to the height of the tubing, the regiment is moved and the support is erected in the order described below.

When the coal is dredged by drilling and blasting method, a skimmer over the upper rim 6 builds a temporary safety shelf 18 from round wood or plates, and from under its protection, makes a frill, drills and charges a series of holes, and then lowers the drill and hangs it under the working platform 2 ” Then, opening lane 16 and winding about 1 m of rope 3 from winch drum 2, using a special clamp, attaches it to l de 16 and descends to a safe place on a sling or shtrek (fig. 4 shows the position of the shelf before blasting holes).

After blasting holes and airing the bottom, the sinker pulls the rope trance from the corner stuck on it, remotely closes the beam 16, pulls on the rope 3, and then rises along the rope ladder 15 to the working platform 1 and from the safety shelf 18 strips the bottom and locks in the fixed space, then raises the strings to a new fastening step.

To raise the shelf to a new spraying step, the skip 13 is pulled all the way into the sleeve 12. With the further winding of the rope, the shelf is lifted by pushing it to the block 10, which supports the support 11 from the tubings 17. At the same time, the supports 8 slide in the slider sleeves 9. After the shelves rise by an amount somewhat greater than the height of the tubing, the winch is turned off and locked, and the stops 14 are turned and the shelves hang on these stops (the position of the shelf in Fig. 5), then the skip 13 is fixed with a hook (not shown) , from the winch is unwound at a length sufficient to lift the blocks to the height of the tubing, the block 10 with the gripper 11 is lifted, moved by hand, and the tubing 17 is brought under the gripper 11 (Fig. 6). Next, the entire ring support is fully assembled. The backbone is simple7
