(57) Abstract:

The invention relates to mining, and specifically to means of extraction of coal with a scraper delivery of the stope. The objective of the invention is to improve the performance and reliability of skreperistov installation. Scaperotta installation for the extraction of coal seam flat and inclined bedding includes a power winch attached to one ends of the cables installed on the same flank lava seperatley attached to the ropes, and the loop station installed on another flank lava and bound with ropes. It is equipped with mobile platforms, on which are mounted traction winch and air station lashing in the workings and with the mechanisms of their simultaneous movement in the process of schreberiana. Seperatley fixed at a distance l = L/n from one another, where L is the length of the front of schreberiana; n is the number scremerston to install. Air station made either in the form of a double-drum winch, reel which is wound a rope pulling hoist, which simultaneously attached seperatley, either in the form of two bypass drums horizontally spaced axes, way winch ropes, zapasovany for by-pass the reels on the lower branches are fixed seperatley, and the upper skipped over scremerston and attached to the drum idling traction winch. The working length of travel of the traction winch and the bypass station relative raskreplenija mobile platforms can be equal step podvigina lava for one cycle or a multiple of it. 1 C.p. f-crystals, 5 Il.

The invention relates to mining, and specifically to skreperistov excavation of coal.

Known scaperotta installation including Executive body, made in the form of planes and scrapers moving along the bottom through the traction drive station [1].

The closest analog is scaperotta plant for development of coal seams, consisting of actual scaperotta and several scraper boxes, pivotally interconnected with the possibility of rotating them relative to each other in the plane of the layer, double-drum winch installed on a mobile platform, and installed in the ventilation passage of the guide beams with by-pass block and unloading rails on the conveyor roadway [2].

Under the th "train".

The aim of the invention is to improve the performance and reliability of skreperistov installation.

This goal is achieved by the fact that scaperotta installation for the extraction of coal seam gently inclined bedding, including traction winch attached to one ends of the ropes and installed on one flank lava seperatley attached to the ropes, and the loop station installed on another flank lava and bound with ropes, equipped with mobile platforms, on which are mounted traction winch and air station lashing in the workings and with the mechanisms of their simultaneous movement in the process of schreberiana coal, seperatley attached to the rope winch at a distance l = L/n from one another, where L is the length of the front of schreberiana, n is the number scremerston, and air station made either in the form of a double-drum winch, reel which is wound a rope pulling hoist, which simultaneously attached seperatley, either in the form of two bypass drums horizontally spaced axes of rotation are parallel to each other at a distance equal to the distance between the lines of the winding drums thee is in, and the upper branches of the ropes skipped over scremerston and fixed to the drum idling traction winch; the working length of travel of the traction winch and the bypass station relative to mobile platforms equal step podvigina lava in one working cycle or a multiple of it.

The invention is illustrated by drawings, where Fig. 1 shows a diagram of skreperistov installation in the lava, and Fig. 2 - section a-a in Fig. 1; Fig. 3 - section b-B in Fig. 1; Fig. 4 is the same cross section B-B in Fig. 1 according to the second variant (with bypass cable blocks) of Fig. 5 - section b-b In Fig. 1.

Scaperotta installation for the extraction of coal seam gently inclined bedding consists of a traction winch 1 attached to one ends of the ropes 2, scremerston 3, attached to the traction rope 2, and bypass the station 4. Traction winch 1 located on one side of the lava, and air station 4, located on the other flank lava installed on the movable platform 5, which during schreberiana (work) raskreplyayutsya in the mines.

The movable platform 5 is equipped with mechanisms for synchronous movement of the traction winch 1 and the bypass station 4 relatively lashing platforms other shifting mechanism, made in the form of hydraulic jacks 6 for lifting platforms and hydraulic cylinders 7 to move the platform in a horizontal plane at the step podvigina lava. The working stroke of the mechanism for moving the traction winch 1 and the bypass station 4 relative to the mobile platform 5 is step podvigina lava for one cycle.

Air station 4 is made in the form of a double-drum winch, reel which is wound the rope 2 traction winch 1. To the traction ropes attached 2 seperatley 3 at a distance from one another, which is determined from the expression l = L/n, where L is the length of the front of schreberiana (lava), and n is the number scremerston to install. Air station 4 can also be made in the form of two parallel installed the drum horizontally spaced axes of rotation, with seperatley 3 are attached to the lower branches of the traction rope 2. The distance between the installed cable reels (or blocks) is equal to the distance between the line winding traction rope 2 drums traction winch 1.

Extraction of coal by the application of the proposed skreperistov installation is carried out as follows. Traction winch 1 is installed on the conveyor roadway (which are stated in the lava at a distance l from one another.

Blasting of coal is carried out drilling and blasting method or from long wells drilled parallel to the longwall face of the conveyor or ventilation drifts or boreholes drilled from sublevel drifts (prosekov), passed between the conveyor and ventilation drifts.

After blasting coal included traction winch 1 on a direct course, and the drums of the winch bypass station 4 disinhibited and traction ropes 2 freely retracted with them, seperatley 3 are filled with coal and transport it along the lava on the distance l. Upon reaching the first traction winch 1 scremerston 3 gathering conveyor and unloading of coal is the reverse of the installation progress: drums traction winch 1 disinhibited and drums of the winch bypass station fades away and seperatley 3 make idling at a distance l. This Shuttle work on skierowaniu coal lasts as long as is reasonably complete filling scremerston 3 repulsed by coal. At low filling coal scremerston 3 is filing skreperistov installed on the bottom on the value of 250-300 mm mechanism shifting when lashing mobile platforms 5 and schreberiana coal prodavnica with mobile platforms 5). When the shifting of the movable platform 5 on the new section of the mechanisms of movement winches (hydraulic jacks 6 and 7) returns to its original position, and the movable platform 5 raskreplyayutsya again in the mines.

When performing the bypass station 4 according to the variant with two parallel mounted cable reels (or blocks) with a horizontal arrangement of their axes of rotation of the scraper works are carried out in a similar way with the only difference that the traction winch 1 is double-drum: single drum stroke, the other is idle.
