Increases reliability of the vehicle by simplifying its design and security of cargo delivery process. 1 C. p. F.-ly, 2 Il. The invention relates to mining and transport, and in particular to means Motiva road, designed for bespovratni delivery of equipment, materials and people (Mining and quarrying transport. - Vol. 7. - M.: Nedra, 1961, S. 186, Fig.8.3).The road is a transport system consisting of branched monorail track with switches and moving it offline trains. Cargo is carried in containers, packages or trays suspended from the cargo trucks.However, when using the monorail as a means of delivery in the mine workings largely attenuated fastening generation, which reduces the safety of its use. Also the disadvantage of this invention is the design complexity, which is the large number of mechanical parts.Closest to the claimed device is selected as a prototype vehicle (Veh. St. SU 962657 And class. E 21 F 13/02), comprising a platform, movably mounted in the guide, rope winch, the rope which is connected with the platform, means mounting the winch and tool rope tension. The vehicle is equipped with a trailer associated with the platform, a reel wound with them the rope is received on trailers from opposite sides of the platform.However, the drawback is the need of recessed grooves in the soil at their height, which is time-consuming and insufficiently reliable in operation.The objective of the invention is to increase the reliability of the vehicle by simplifying its design and security of cargo delivery process.The problem is solved due to the fact that as the road is made of single panline scraper conveyor with side rails, inside which is placed the composition grusauskas trolley mounted for movement along the rod road two winches placed at the beginning of the road, and a block located at the opposite end of the road, with both the end of one branch of the rope is attached to the first and the last groteluschen trucks, and the other branch of the rope is placed in a guide attached to the bottom of the truck under it.In addition, the side guides of the rod road equipped with brake springs installed at a distance from each other on both sides.Indeed, the proposed construction grusauskas road simple, the delivery process is safe, due to this increased the reliability of its work.Synod, it differs significantly from known and matches the criteria of novelty and inventive step, and its simplicity and clearly demonstrates its industrial applicability in the coal industry.The essence of the technical solution is illustrated in the drawing, where Fig.1 presents a General view of the trackless floor grusauskas road, in Fig.2 - section a-a of Fig.1.Trackless floor grusauskas road includes single panline 1 with the side rails 2, inside the rod 1 has a composition grusauskas trucks 3, two winches 4, placed at the beginning of the road, block 5, located opposite the winch end, the branches of the rope 6 is attached to the first and the last groteluschen trucks 3. Truck mounted on the platform 7, the bottom of the trolley 3 is equipped with a guide 8 for placement of her rope 6. The side guides 2 includes brake spring 9. Himself panline 1 is fixed in the soil produce the anchor 10.Offer trackless floor grusauskas road works as follows.Panline 1 is fixed in the soil produce the anchor 10, the panline the composition is a platform 7 with Sony becoming 1 provided with side rails 2 with brake springs 9.When you enable both winches 4, located at the beginning of the road, the rope 6, moving along the guide 8 of the bottom of the truck 3, rounded block 5, located opposite the winch 4 end unwound from one winch and wound on the second. Due to this movement of the trolley forward.After the composition grusauskas trucks 3 with the load reaches the extreme point, the winch off, the cargo is unloaded. Then the winch is turned on again, the rope 6 from the second winch 4 is unwound and wound on the first part grusauskas trucks 3 moves ago. 1. Trackless floor grusauskas road, including being located on the platform mounted to move with the help of winches and blocks, characterized in that as the road is made of single panline scraper conveyor with side rails, inside which is placed the composition grusauskas trolley mounted for movement along the rod road two winches placed at the beginning of the road, and a block located at the opposite end of the road, with both the end of one branch of the rope is attached to the first and the last groteluschen trucks, and the other branch Kahn who eat what side guides rod road equipped with brake springs installed at a distance from each other on both sides.

SUBSTANCE: method for extraction and underground use of coal includes cleaning extraction and dumping of coal, fixing and controlling ceiling and transporting coal along face to drift. On the drift, in moveable generator, coal is pulverized for intensive burning with use of jets in water boiler firebox, where high temperature of steam is achieved (about 1400 C°), enough for decomposition of water on oxygen and hydrogen. These are separated, then oxygen is fed back to jets, and hydrogen is outputted along pipes and hoses in drifts and shaft. Variants of underground generator for realization of this method are provided. Also provided is method for extraction of disturbed coal beds by short faces. It includes extraction and dumping of coal on face conveyor, fixing of ceiling behind combine, moving conveyor line and support sections in direction of cleaning face displacement, control of ceiling with destruction and partial filling. Extraction of coal is performed in short curvilinear faces by long stripes along bed, in straight drive without forwarding drifts, with preservation and reuse of ventilation and conveyor drifts, equipped with mounting manipulator robots, with fixing behind combine by automatically operating support deflectors without unloading and displacing sections in area of coal extraction. Extraction and transporting of coal is performed by fast one-drum combine and curvilinear reloading conveyor, supplying coal to drift conveyor or immediately to underground gas or energy generator placed immediately on drift. Also proposed is face scraper conveyor for realization of said method, wherein pans are made with step along front face profile, greater, than along back one, while forming common line curved towards face with constant curvature. Also proposed is a method for controlling complex for unmanned coal extraction.
EFFECT: higher efficiency, effectiveness, broader functional capabilities.
