Description

39. Simultaneously with the breaking of the rock by the combine 14 and the fender 33 bodies and its loading, the anchor holes 7 are drilled. At the same time, the anchors 8 are installed in the roof of the mine using drilling machines 6. The feeders 5 are set up for drilling by moving the holders 37 along 36. After drilling the next set of anchor holes, pv is carried out: moving the walking support. The roof is supported 18. Thus, the continuity of the penetration and fastening of the roof of workings of various shapes is ensured. Possible destruction of rocks casting fortress. 3 il.

The invention relates to tunneling equipment and is intended for use in excavation of mine workings or tunnels of various cross sections and sizes in rocks of various strengths, including strong stressed ones, where the use of combine harvesters, made only by milling tools with cutting tools, is ineffective due to large wear incisors and low penetrations.

The aim of the invention is to expand technological capabilities and increase productivity.

FIG. 1 given a general view of the complex tunneling in the mine; in fig. 2 shows section A-A in FIG. 1 ongoing development and tunneling complex; in fig. 3 is a view B in FIG. 1 on the complex from the butt in transyurytnom position.

The proposed complex is as follows.

The complex includes a combine of 1 selective action, a loading crane 2, vehicles 3, a safety spacer-walking support 4 with 5 drilling machines 6 installed on the feeders for drilling wells 7 under the rod support 8 in combination with a roll tightening 9.

Combine 1 includes a self-propelled chassis 10, a feeder 11, a conveyor 12, an arrow 13 with a milling cutter {a working organ 14 on a rotary turret 15.

The safety bolt 4 includes pairwise interconnected by means of longitudinal traverses 16, spacer racks 1 equipped in the upper part with an overlap 18, bypass rollers 19 and 20, and deflecting rollers 21. On the transverse traverse frames 22 and 23, connecting pairs of racks, allowing you to move along height fixed shelves 24,. on which, with the possibility of longitudinal (along it) movement in the guides, by means of the actuator 25, the rotator 26 is fixed with the actuator 27 rotated to the side of the longitudinal axis of the lining of the head 28, on which, using hydraulic cylinders 29 and 30, is fixed in the plane

Arrows 31, carrying holders 32 with fasteners fixed on them with the possibility of sliding - strikers 33 with rock-breaking bits or peaks 34.

On the spacer columns there are fastened drums 35 with coils of stoppers laid on them, as well as guides 36 with holders 37 for mounting the feeders 5 with the possibility of their moving in the longitudinal direction.

direction.

The overlap 18 is provided with hinges 38, on which side flaps 41 are fixed by means of supports 39 with clamps 40. Clamps 42 are provided for fixing the buildings in the extended position.

To move the traverse 22 / and 23, hydraulic cylinders 43 are provided, mounted on the uprights 17. The uprights 17 in the lower part are provided with walking mechanisms in the form of

supporting skis 44 with their 45 hydraulic cylinders built in.

The operation of the complex is as follows. Combine 1 with its chassis 10

placed in the face together with the loader 2 and the vehicle 3. A mobile vehicle is placed above the combine. pre-strut walking lining 4 with overlap 18 and flaps 41, which

set with the help of props 39 on racks, providing overlapping of the roof of the excavation. The drums 35 on the uprights are equipped with tightening rolls under the overlap 18 with the help of bypass rollers 19 and 20 and deflecting rollers 21.

From the deck 24 of the safety support, the treatment is carried out both by the upper part and by any other part by the strikers 33 with rock-cutting tools 34,

Claims (1)

placed in the holders 32, moving the boom 31 using the rotator 26 and the hydraulic cylinders 30 and 31 to the desired position. Either bits or peaks are used as rock cutting tools, depending on the strength of the rocks being destroyed. The destruction of rocks in the lower and middle parts is carried out by the fender bodies 14 of combine 1, moving the boom over the face. In the presence of strong rock strata, they are destroyed by the impactors by the bottom 33. The crushed rock is loaded with a combine using a feeder 11 to the conveyor 12 of a combine and then using a transfer / driving device 2 into vehicles 3.I Simultaneously with the breaking of the breed. and the fender bodies 33 and its loading drill the anchor bores 7 and install roof anchors 8 using drill machines 6 on the feeders 5. Setting the feeders The drilling is done by moving them of the holders 37 along the guides 36 and turning It is the axis of the guides. After the next set of anchor holes is drilled, the walking support is moved in the direction of penetration, maintaining the arch by overlapping 18 with the puffs 9 laid on it, reeled up with the drum 35. Thus, continuous iptoby iBHOCTb of the penetrations are secured rocks of different strength. If it is necessary to remove equipment from the bottom, when using hydraulic cylinders 43, lower the overlap 18 to combine 1, lift the lower ends of the uprights 17 with supporting skis 44 and move the support along with the combine to a new place of work. The invention of the penetration complex for the sinking of horizontal and low-intensity development, including a self-propelled combine with an executive body on the boom and a safety lining, containing vertical extension struts located on the sides of the combine, About tl and ch and y and. so that, in order to expand its technological capabilities and increase productivity, sleep complex connecting the hydraulics with longitudinal crossbars and transverse crossbars with mechanisms for their vertical movement along hydraulic legs and with a deck fixed on them mounted on the latter can be rotated relative to the longitudinal axis by an additional boom with a striking tool at its end mounted on longitudinal crossbars along them by rotary devices for drilling holes, placed on the hydraulic posts by drums with a roller tightening and fixed on the floor about tilting rollers and guide rollers for skipping over the latter, while the overlap is made with side flaps that have fixing struts connected to the hydraulics.
