The disadvantage of such a harvester is: the impossibility of choosing the optimal attachment points due to the fixed position of drilling equipment; drilling installation is possible only stopped when the harvester due to the dynamic loads resulting from its operation; sequential execution operatemaintain the setup time of the drill head at the point of drilling according passport fastening.

Famous tunnel complex, including continuous miner creeper with an arrow-shaped working body, the rotator, the loader with the conveyor paleosuchus installation and timberman [2]. The timberman consists of spacer beams, interconnected with the machine body, cylinder thrust with reference skis, yosin, sliding bearings, drilling machines, located on two sides relative to the body of the harvester, manipulators, adjustable pull, individual remote control of drilling machines.

The disadvantages of this complex are: when weak roof or in areas of geological faults cannot use drilling machines directly in the face without advance fixing anchor support; profile of the working certain; selective extraction of coal, impossible when processing combine strong breed, you will need to drill carriage or installation that clutter the slaughter; and technology for developing ineffective due to the alternating arrangement of downhole equipment in the mine, which is possible only in workings with the corresponding larger cross-section; a limited number of drilling machines in the line of attachment 2; indiv the tion of the total effort during drilling.

The objective of the invention is to increase the efficiency of the drilling of wells (holes) for anchoring and drilling and blasting operations when conducting mining tunneling machines in various mining and geological conditions, increase productivity, increase the speed.

To solve the task of sinking the complex includes a continuous miner with a working body spacer beam with cylinder thrust, conveyor and manipulators with means of drilling and strained, with arms linked, for example, the spacer beam can be rotated by means of shaft fixed on her front end, the rear end of which is fixed to the device turning on sliding bearings, the shaft is connected with the arms through the sliding glass fixed and movable templates with adjustable transversely of the axis, for example, around the circumference of the support for attachment of the handles, and with feeder Cup relative to the shaft and the rolling pattern relative to the glass acting as a simultaneous total supply multiple drill heads to the point of drilling template according to the passport of fastening and drilling and blasting operations when conducting mining.

Manipulieren adjustable thrust with a movable template, the parties which in the initial position parallel to the axis of the shaft of the timberman and are within its length. Templates are provided with adjustable supports with clamps. The shaft is made hollow and is connected to the suction unit by means of a branch pipe.

This embodiment allows: simultaneous General flow pattern rotary gripping device with drill heads - to-point drilling, with elements of the frame lining to the place of their installation; compact placement of downhole equipment; to choose the optimal attachment point of generation, depending on the stability of the roof, to exclude the effect of "marking time" of the roof, to ensure the centering of the timberman-axis output.

In Fig. 1, 2 shows the proposed tunnel complex, side view, And is in the working position, B is in the transport position of Fig. 3, 4 same, front view; Fig. 5 is the same, top view; Fig. 6 is a side view, and Fig. 7, 8, 9 respectively sections along a-a, b-B and C-C of Fig. 6.

Tunnel complex consists of harvester and timberman. The harvester includes a working body 1, the loader 2, the rotator 3, the frame of the conveyor 4, the vent becoming paliatsos 5 remote control 6. The timberman, Fig. 4, consists of a hollow shaft 7, article the retainer 12, the rack shaft 13, the device rotation of the shaft with the cylinder 14, Buchs 15, the nozzle 16. Manipulators of timberman consist of the two parallelograms: main 17, 18, 19, 17 General, Fig. 4, the auxiliary adjustable sides 20, 21 with adjustable pull cylinder configuration 26, forming at the base of the triangle with varying side length along the axis of the shaft due to the relationship of the rolling pattern with the feed cylinder 11. The provision of the auxiliary manipulator adjustable side 20 provides automatic rotation of the drill head with a barbell from a parallel position relative to the shaft in position at a selected angle to the roof framing. Manipulators are equipped with rotary gripping devices 22, which are interconnected with drill heads 23, or frame supports 28, Fig. 2. Rotary gripping device 22 is equipped with hydroporinae, piston cavities are connected by pressure hoses (hydraulic hoses for flow of fluid, which provides accounting irregularities boards develop the necessary automatic preload lunettes drill heads in the drilling points when moving the rolling pattern. Movable and stationary templates are provided with adjustable supports 24 for fastening manipulatability on the specific location of the drill head according passport fastening framing anchor shoring, the drilling and blasting pattern or frame lining, which is achieved by the ability to move the supports 24 in the guide rails 35, Fig. 5, for example on the circumference to the axis of the shaft of the timberman with subsequent fixation clamps 25. Adjustable rods 21 are adjusted by reducing or spreading cylinders settings 26 swivel-gripper-shaped cross-section as production and slaughter. The templates supplied with brackets 27 of the mounting cylinder supply, common for all mice (drill head). Shaft timberman has two options mounting: through axle box 15 is fixed to the front on the rotary device 3 of the combine, the rear on the frame of the conveyor 4, it is possible only sequential execution of operations on the rotating drum and mounting; or based on the distance the beam 29, the thrust cylinders 30 with reference skis 31 and cylinder adjustment 32 and back through the additionally installed sliding bearings 33, and it is the combination of operations on the rotating drum and the bracket. The choice depends on the stability of the roof and adopted the technology for mining. The second option is provided to adjust the timberman relative to the harvester and the axis of the developing cylinder adjustment 32 and the removal to the extent necessary allows the support device 34, designed as a rolling surface with two wheels, to compensate for the offset shaft timberman respect to the axes of development and harvester, i.e. to ensure the centering of the timberman axis production while the thrust gripper-rotary devices in the sides and roof framing. Ventilation becoming 5 paleotsunami installation combine connected with the shaft drilling rig pipe 16.

The tunnel complex is as follows:

a) when carrying out excavations in areas with unstable roof and geological disorders (adverse conditions). After processing the slaughter of the working body 1 in a step value fastening generation and notches on the following removable strip drill head 23 of the cylinder 11 filing by reducing served (manipulators from the transport position disclosed in the working simultaneously) with the remote control 6 to the point of drilling blast holes for bolting to their spreading out to the sides and roof framing for slaughtering. Drill head 23 while are inclined to the bottom and into the zone of action of the tool are not (Fig. 1, 2), does not hinder the work of the working body of the harvester for the blasting, and loading the body 2 through the loading of the rock mass. The way is at the end of the drilling reverse inclusion feed cylinder 11 is movable template 10 is pushed against the stationary 9, the drill head is returned simultaneously to the initial position (arms folded). Thus the trajectory of the structural elements of the timberman not hinder the movement of the working body of the harvester in its extreme positions, which is achieved by the interaction of two pivotally interconnected on each arm drill heads parallelograms with sides 17, 18, 19, 20 and triangle with the same sides as part of the side 17 of the parallelogram from the attachment to a stationary template to the place of attachment of the other side of the triangle of thrust 21 and cylinder adjustment 26 (which are pre-built on a concrete production) and variable third party, formed by glass 8 by moving the movable template 10 of the feed cylinder 11. Folding in the original position or hinged into position manipulators with drill heads occurs simultaneously due to their location on the shared templates in General supply. The inclination of the holes on the bottom due to the need for rapid mounting anchors at a very low roof framing. After drilling set anchor or remain rod-tube with disposable cutters with a fixing resin, and then the cycle repeats;

The operation for mounting the generation combined with blasting and loading rock mass on the combine, the dynamic load of the harvester on the timberman is not transmitted. When installing a drill head 23 is less than that required anchors in the same row, for example two, of the drill head are shifted across the output required value by turning the hollow shaft 7 of the timberman around the axis of the cylinder of rotation 14. When the work of slaughter;

C) when conducting generate mixed bottom, with selective excavation of coal miner and rock drilling and blasting method (when the fortress rocks exceeds the capabilities of the harvester); after excavation of coal on the length of the bore-holes of the Cup 8 of the hydraulic motor 12 is fed forward to thrust the shaft of the drill heads are configured on the template 9, 10 (adjustable feet 24) according to the location of the holes on the passport blasting in the same row. After drilling the first row permutation boring heads to a new number is also performed with the remote control 6 cylinder supply 11 that moves the movable template 10. Moving the drill heads in a row is a cylinder of rotation 14. When driving combine the timberman is in the transport position with the remote control by folding its structural members parallel to the axis of the shaft 7, Fig. 1B. When bracing for excavations by frame structures using gripper-swivel device 22 establishes the frame supports and the installation is done simultaneously by submitting them to the sides of excavations, Fig. 2B, as a timberman at anchor bracket.

When five-bar frame supports are five manipulators with turn signals the AI of the drill carriage, used for blasting (drilling and blasting) in combination with a loading machine, heading machine allows to compactly accommodate downhole equipment used in the traditional way of mining excavation in hard rock by drilling and blasting in a single tunnel complex. The ability to move the Cup 8 on the shaft of the timberman 7 the hydraulic motor with latch 12 allows the place of erection of the permanent anchor lining to produce: ahead of slaughtering, by mounting in drilled wells "punctured" or inclined anchors; behind the lines of the face to the desired value, which is caused by the passport mounting with the process of mounting or without combining with blasting, and loading of the rock mass; immediate selection of the optimal site of attachment with the change in the resistance of the lining during excavation.

When spreading out the sides and the roof framing at the point of drilling lunettes boring heads is a point thrust equal to the force flow during drilling, with the spacer beam with the total load, with a roof is not in contact, as occurs in the known tunnel complexes, where the beam is held apart directly into the roof, causing the complex allows to combine the process of anchoring with the breaking and loading rock mass without the presence of people at the point of drilling and installation of anchor simultaneously around the perimeter of the mount output. With a slight movement of the rolling pattern is provided by the speed from the position of the drill head in the initial position, when inserted rod-anchor to the working position when drilled wells, for example, with simultaneous installation of the anchor when the disposable cutters and remotely.

The timberman can be performed offline on the chassis of any of the drill carriage on wheels, rails and tracks, playing the role intervalley drilling machine in combination with a loading machine in the pit.
