The invention relates to mining and is designed for mechanization of conduct horizontal and slightly inclined workings drilling and blasting method, reducing the labor intensity and improve the performance of the tunnel works. The proposed complex with self-propelled safety shield allows to mechanize the process of cleaning crushed rock mass, drilling holes in the bottom and under the anchors, installation of anchors, eliminates the need to drain it from the bottom to a safe distance before blasting operations and the construction of the temporary protective lining in the wellbore area.

Famous tunnel complex for mining hard rock "Tunnel complex vzrivoopasniy (PCVN-04)" [1]. The equipment of the complex has the following composition: reception wedge portion with a loading module, a hopper for srivanalai, discharge scraper part (the pipeline), the mechanism semiperiodic, pumping station, unit and remote control, hydraulic manipulator with drill machine on a special gantry trolley, which moves along the rod material handler a special mechanism.

The disadvantages include the lack of a safety lining; the process semiperiodic by means of hydraulic cylinders and chain device, attached to the anchors, anchored in the soil expressed otci the breast bottom.

The closest structural device is the "Tunnel complex vzrivoopasniy (PCVN-2008)". The structure of the considered complex includes: reception wedge portion with a loading module, a hopper for srivanalai, discharge scraper part (the pipeline), the mechanism semiperiodic, pumping station, unit and remote control, hydraulic manipulator with drill machine on a special gantry trolley, which moves along the rod by a special mechanism, the safety shield comprising racks and safety shields and moving on rails on the sides of the hopper at a special running carriages. Loading operations and drilling is underway at the critical zone under the protection of the safety liner. Drilling blast holes for the anchors is performed using drilling equipment through special openings in the protective lining.

The disadvantages of the considered complex is the lack of mechanized traction drive trucks safety lining which is moved manually along the guide rails on the sides of the hopper for srivanalai. This causes additional costs of manual labor drifters moving the support, and the need to stop operation of the equipment at the time of the move supports dictated by the requirements of the machinery safety is snasti.

The aim of the present invention is to improve the construction of the tunnel vzryvozashchitnogo complex to eliminate these disadvantages, i.e. the development of a mechanism for moving the chassis trucks safety lining that ensures its supply to the bottom and discharge from the bottom without the presence of people and is controlled from a panel located in the rear of the complex.

According to the invention this objective is achieved in that the tunneling vzrivoopasniy complex comprising receiving klinovuyu part from the loading module, a hopper for srivanalai, discharge scraper part, the mechanism semiperiodic, pump station, control panel, hydraulic manipulator with drill machine on a gantry trolley, which moves along the rod material handler special mechanism is equipped with a safety shield, consisting of racks and safety shields, which moves along rails on the sides of the hopper by means of the traveling carriages with electric drive. The internal part of the guides on the sides of the hopper for srivanalai made in the form of a toothed rack and the wheels of the carriage trucks safety lining in the form of toothed wheels for locomotion by rail. Inside the traveling carriages are actuators that transmit the movement of the gear wheels. Electron Beenie running carriage is made from cables, wound on a reel located at the tail end of the hopper for srivanalai and having the automatic winding mechanism that pulls the cable from the drum while moving the traveling carriage along the wedge portion to the bottom and wind the cable back onto the drum while moving the traveling carriage from slaughter.

The essence of the proposal is illustrated by drawings, where:

figure 1 presents a General view of the complex (side view);

figure 2 presents the node of figure 1;

figure 3 presents a General view of the complex (top view);

figure 4 presents a view of the complex in cross-section a-a of figure 1;

figure 5 presents the node B in figure 4.

According to the invention, the complex consists of the loading module 1, the hopper for srivanalai 2, discharge scraper, part 3, mechanism semiperiodic 4, pump station 5, the control unit 6, a hydraulic manipulator with drill machine 7 on a gantry trolley 8 moving on the V-rod loader 9, a safety lining 10. The safety shield is moved along the guide rails 11 on the sides of the hopper 12 to srivanalai 2 by driving the carriage 13. In the tail part of the complex houses the reel 14 for winding the cable 15, exercising the power supply chassis of the carriage 13. The reel 14 is equipped with automatic cable winding 15, which allows unwinding diameter is Ivate cable when moving the carriage 13 to the slaughter, to uncoil the cable when moving the carriages from slaughter and maintain unwound the cable tensioned position to avoid sagging. Inside the guide 11 has a toothed rack 16. Wheels 17 of the traveling carriages 13 safety lining 10 is equipped with teeth come into engagement with the gear rack 16 and move the running gear of the carriage 13 along the guide rails 11 along the sides of the hopper for srivanalai 2. The drive wheel 17 is mounted inside the chassis of the carriage 13. Management of the running carriages 13 is performed from the remote control 6 complex.

The operating procedure of the tunnel vzryvozashchitnogo complex.

Before you start blasting the complex is located at the breast slaughter. Drilling equipment 7 is given in the trailing portion of a hopper for srivanalai 2. The safety shield is also moved by means of the traveling carriage 13 in the tail part of the hopper for srivanalai 2 and is located above the drilling equipment 7. After blasting holes and ventilation generation begins unloading the main part of the pile wedge material handler 9 on the discharge scraper part 3. The rock mass that has fallen on the side of the hopper to srivanalai 2, by means of hydraulic cylinders sides of the hopper and gravity poured on the V-loader 9 and also by the scrapers part 3. As unloading of the pile is podvigina to the of the complex to the breast slaughter mechanism semiperiodic 4. While the rest of the pile gets to the loading module 1 and is transported to the scraping portion 3. Upon completion of the unloading of the total volume of rock drilling equipment 7 under the protection of the safety lining 10 is moved along the rod material handler 9 to the bottom for drilling blast holes for the anchors, and then slaughter. The safety shield is moved along the sides 12 of the hopper to srivanalai 2 along the guide rails 11 by means of the traveling carriage 13, a gear wheel 17 which come into engagement with the gear rack 16 on the inner side of the guide 11. The guides 11 are enclosed design keeps the rack 16 from contact with the rock stuff. After drilling the shaft and mounting production cycle of operations is repeated.
