The invention relates to mining. Intended for mechanization of conduct horizontal and slightly inclined workings brown-explosive way, reducing the labor intensity and improve the performance of the tunnel works. The proposed complex with rotating 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 bottom-hole zone, provides protection of equipment from the effects of the explosion.

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 is on the device, fixed to the anchors, anchored in the soil to develop in the breast slaughter.

The closest structural device is the "Tunnel complex vzrivoopasniy (PCVN-2008)". The structure of the considered complex include 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 protection of the equipment from the effects of the explosion and flying pieces of rock mass, because in mode srivanalai are only reception of the wedge portion from the loading module and the hopper for srivanalai. The rest of the equipment complex explosion may be damaged. In parvo is all this boring machine, which, at the time of the explosion is at the tail end of the hopper and has no capability for removal at a greater distance.

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 the safety devices, effectively protecting the drilling equipment of the complex from the blast and flying pieces of rock.

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, moving on rails on the sides of the hopper and comprising uprights and safety boards, which have two sections. The front section pivotally attached to the rear section and can be rotated downwards by means of two hydraulic cylinders located under the fences and controlled with the remote control, the front section in the lower position provide is ASITO drilling equipment from the effects of the explosion.

The essence of the proposal is illustrated by drawings, where

figure 1. presents a General view of the complex after blasting;

figure 2. presents a safety shield with a raised front section (side view);

figure 3. presents a safety lining down the front section (side view);

figure 4. presents the location of the equipment complex with raised front sections of the safety lining (front view).

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 that includes 10 hours and safety boards consisting of a front section 11 and the rear section 12. The safety shield is moved along the guides 13 on the sides of the hopper 14 for srivanalai 2 by driving the carriage 15. The front section 11 of the safety shields are attached to the rear sections 12 by means of hinge joints 16. Lift and hold the front sections in a horizontal position, and the lowering of the front sections is carried out by means of hydraulic cylinders 17. The front sections is made with PU is to management 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 to the tail portion of the hopper to srivanalai 2 and is located above the drilling equipment 7. The cylinders 17 are folded and lowered the front section 11 of the safety shields that protect drilling equipment 7 from flying pieces of rock mass in the explosion. 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. Before lifting the sides of the hopper for srivanalai 2 hydraulic cylinders 17 are moved apart and raised the front section 11 of the safety liner. As unloading of the pile is podvigina 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 the rock mass of the storm is inoe equipment 7 under the protection of the safety lining moves rod material handler 9 to the bottom for drilling blast holes for anchors and then on the bottom. The safety shield is moved along the sides 14 of the hopper to srivanalai 2 guide 13 by means of the traveling carriage 15. After drilling the shaft and mounting production cycle of operations is repeated.
