Embodiment Construction

[0010] Those skilled in the art can implement according to the technical scheme and the accompanying drawings. Next, according to the attached figure 1 The gangue transportation process is described, so as to better understand the content of the present invention.

[0011] The gangue mine car 13 coming from the excavation face is unloaded into the gangue unloading pit 1 through the gangue unloading device 12 (such as a cage), and then sent to the gangue crusher 3 through the scraper conveyor 2 for crushing, and the crushed gangue falls into the In the lower coal bunker 4, the broken gangue in the lower coal bunker 4 is lifted to the upper coal bunker 6 by the coal conveyor belt conveyor 5, and the coal feeder 7 is started to reverse, and then transported to the gangue bin 9 by the conveyor 8. The equipment 10 is loaded into the mine car 11 and sent to the goaf for filling.

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 systemimproves 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 [0001] The invention relates to an underground coal mine transportation system, in particular to a gangue transportation and filling system. Background technique [0002] At present, coal mines have adopted a waste rock filling system in order to prevent gangue from going into the mine and reduce environmental pollution in transportation links and ground gangue piles. Gangue filling is to crush the gangue produced in underground tunnels and transport it to the goaf for filling. The layout of the gangue filling system is as follows: the gangue produced from the excavation roadway is loaded into the mine car, transported to the gangue yard through the transportation roadway, and then converted into a winch for lifting, and the mine car is lifted one by one to the previous mine car through the track up the mountain roadway. The gangue bin in the section is crushed and then filled into the goaf through the transportation channel. Due to the limited transportati...
