The invention relates to equipment for the coal and mining and tunnelling, in particular for carrying out horizontal and inclined workings.Known unit for sinking mines along.with. 1661429, CL E 21 D 9/10 (publ. 07.07.91 bull. 25), comprising a support frame (portal), which osnago unit is that almost on one site (site) is concentrated all functional equipment (drilling rigs, truck), which greatly complicates the control system and the repairs.The aim of the invention is the maximum unification of functional equipment of the existing complex with the expansion of the range of use altitude workings.This objective is achieved in that in the complex for mining, including spatial frame gantry with support beams on the carrier trolleys inside beams telescopically retractable boom with loading bodies, drilling rigs and other equipment placed on the upper area of the portal, the front from the bottom part of the spatial frame of the portal is made in the form movable in the vertical direction of the platform, pivotally connected to the support beams, levers, which in turn by means of hydraulic jacks associated with the hard part of the portal.Comparative analysis of the prototype allows us to conclude that the claimed complex differs in that the front part of the space frame (portal) made in the form of mobile in S="ptx2">Analysis of the known technical solutions (analogues) in the study area leads to the conclusion about the absence of these symptoms that are similar to the main features of the proposed tunnel system, and to recognize that the proposed solution meets the condition of patentability "inventive step".The invention is illustrated by drawings, where Fig. 1 shows a side view of the complex with the maximum upper position of the platform; Fig. 2 is a top view with the maximum lower position of the platform; Fig. 3 - the same, lateral view; Fig. 4 is a view of the complex at the bottom.The complex contains the reference beam 1 with the traction bogie 2, in which the rear parts rigidly connected spatial frame 3 and the front parts are connected by means of lugs 4, 5 fingers, levers 6, the trunnions 7, platform 8, where the drilling rig 9 moving along the guides 10. Raising and lowering of the platform is carried out by means of hydraulic jacks 11, the rod of which is pivotally connected to the levers 6 and the cylinders with the ends of the side walls of the hard part of the portal 3. In the girders 1 are embedded telescopically retractable boom 12, the front ends of which are secured the arms 13 with the bucket the hard part of the portal the oil station 18 and the control station 19.The complex operates as follows. Tunneling cycle begins with the drilling of bore-holes. For this purpose, movable in the vertical direction, the platform 8 is lowered by means of hydraulic jacks from the positions shown in Fig. 1, in the position of Fig. 2. Further drilling device 9 is moved along the guides 10 on the front end of the platform, and after moving complex on track and install it in a working for the drilling position starts immediately for the drilling process, while the buckets 14 and loading equipment 15 are installed in a position that allows you to amuriat at the beginning of the middle lower part of the bore-holes, then the right and left side of the bottom holes, then drilled the top holes. After drilling the entire area of the bottom hole drilling device 9 is returned to its rearmost position, and the platform 8 is raised to its extreme upper position of Fig. 1, and the complex is devoted to safe for blasting distance.After blasting and ventilation cleaning of the rock mass and spatial frame 3, the platform 8 with the pins 7, the levers 6, the fingers 5 and the lugs 4, fastened to the supporting undercarriage bogies 2 beams 1, form a rigid portal, which allows you to skip wagonway face.During the construction of the metal arch support platform 8 is in its extreme upper position and can deliver directly to slaughter all of the elements of the support, including concrete tight and using a drilling rig, the feeders are equipped with special devices to mechanize the work are set to support in the design position.This cycle of drilling completed and proceed to the next one.The proposed solution allows you to extend the range for mining on their height and eliminate the necessity of using special drilling machines with extra long shafts manipulators.
