Abstract
The invention discloses a time-sharing transporting and filling system for underground coal and waste rock. A waste rock discharge pit and a discharge device are built by downward digging at a vehicle entrance end of a mining area transportation park, a waste rock crusher is arranged on the upper port of a lower coal bunker of a primary coal transportation belt machine, and a scraper conveyer is arranged between the bottom of the waste rock discharge pit and the waste rock crusher; a waste rock bin is built in an old tunnel nearby a board-up tunnel outlet of the primary coal transportation belt, and a coal supplier of an upper coal bunker of the primary coal transportation belt machine is changed into bidirectional discharge mode; one waste rock discharge end of the coal supplier is provided with a conveyor to the waste rock bin; and a loading device is arranged at the bottom of the waste rock bin, and crushed waste rocks are filled into a mine car and transported to a gob. The system improves the transportation capability and realizes continuous transportation of the waste rocks by promoting the waste rocks to the upper transportation tunnel of the gob through the primary coal transportation belt machine.
Description
Technical field
The present invention relates to transportation system under the coal mine, relate in particular to spoil transportation filling system.
Background technology
At present, well is not gone up in order to realize spoil in the colliery, reduces the environment pollution of transit link and ground hillock, has adopted the waste filling system.Waste filling is exactly the spoil of underground tunneling roadway output, pulverizes the back conveying and is filled to the goaf.The arrangement of waste filling system is: the spoil of the output mine car of packing into from digging laneway, be transported to the spoil parking lot through main haulage roadway, converting winch again to promotes, with waste bin that is promoted to a last section of mine car, again by transport channel be filled to goaf after the pulverizing by the ginney tunnel.Because the transport capacity in ginney tunnel is limited, can not at short notice all mine cars all be promoted, thereby influence driving speed.In order to make driving speed unaffected, a part of spoil must be mentioned on the ground by auxiliary shaft, make the spoil can not be all in the down-hole backfill.
Summary of the invention
For the not enough problem of lifting capacity that solves the waste filling system, the present invention proposes a kind of transportation filling system that utilizes the timesharing of existing fortune coal conveyor to promote spoil.
Technical scheme is: 1, the car end that advances in the transport park, exploiting field excavates downwards and sets up one and unload the cash hole, unload on the cash hole and be furnished with discharge mechanism, at spoil crushing engine of the bottom coal bunker of original fortune coal conveyor layout suitable for reading, unloading drag conveyor of layout between bottom, cash hole and the spoil feed of crusher mouth.
2. near the old working original fortune coal belt bord-up outlet, build a waste bin again, change the feeder of original fortune coal conveyor top coal bunker into two-way unload-type, unload coal when just changeing, unload cash during counter-rotating, feeder unloads an end of cash and arranges that a conveyer is to waste bin.
3. truck-loading facilities is arranged in waste bin bottom, will pulverize the spoil mine car of packing into and be transported to the goaf.
Good effect of the present invention is: utilize original fortune coal conveyor bord-up to promote spoil to top, goaf haulage drift, improved moving Movement Capabilities, realized that spoil transports continuously, can be the free time of fortune coal transportation spoil (because the fortune coal time be to carry out at interval).Thereby reduced the special-purpose spoil of cover transportation system, can transport spoil as long as on former fortune coal measures system, transform a little.
Description of drawings
Fig. 1 is a schematic diagram of the present invention.
Marginal data: 1-unloads the cash hole; The 2-drag conveyor; 3-spoil crushing engine; 4-bottom coal bunker; 5-fortune coal conveyor; 6-top coal bunker; The 7-feeder; The 8-conveyer; The 9-waste bin; The 10-truck-loading facilities; The 11-mine car; 12-unloads the cash device; The 13-mine car.
The specific embodiment
Those skilled in the art can implement according to technical scheme and accompanying drawing.1 the spoil transportation is described with reference to the accompanying drawings more below, thereby understands content of the present invention more.
The spoil mine car 13 that comes from driving face is discharged into cash hole 1 by unloading cash device 12 (as cardump), send into spoil crushing engine 3 by drag conveyor 2 again, carry out fragmentation, spoil after the fragmentation falls into bottom coal bunker 4, and the broken spoil in the bottom coal bunker 4 is carried to top coal bunker 6 on fortune coal conveyor 5, starts feeder 7 counter-rotatings, deliver to waste bin 9 through conveyer 8 transhipments, by truck-loading facilities 10 mine car 11 of packing into, deliver to the goaf, carry out filling.
Claims (1)
1. down-hole coal and spoil timesharing transportation filling system, it is characterized in that, it is that the car end that advances in the transport park, exploiting field excavates downwards and sets up one and unload the cash hole, unload on the cash hole and be furnished with discharge mechanism, at spoil crushing engine of the bottom coal bunker of original fortune coal conveyor layout suitable for reading, unloading drag conveyor of layout between bottom, cash hole and the spoil feed of crusher mouth; In near original fortune coal conveyor bord-up outlet the old working, build a waste bin again, change the feeder of original fortune coal conveyor top coal bunker into two-way unload-type, unload coal when just changeing, unload cash during counter-rotating, feeder unloads an end of cash and arranges that a conveyer is to waste bin; Truck-loading facilities is arranged in waste bin bottom, will pulverize the spoil mine car of packing into and be transported to the goaf.
