The underground coal mine exploitation operation is often divided into multiple layers, multiple roadways are constructed in a staggered mode, and the roadways are further divided into a gallery and an inclined roadway. The inclined drift further comprises an ascending inclined drift and a descending inclined drift, and the drift bears the transportation function of gangue discharge after blasting. The crushed rock is transported in a short distance on a working surface and in a large track roadway. The traditional gangue discharging process is to load crushed rock into a mine car by a mining scraper or a hydraulic loader. If the mine car is in roadway construction, the mine car filled with the gangue is transported in a short distance through the working face by traction of the electric locomotive, and is transferred to a rail transportation roadway to a wellhead. If the construction is in inclined drift, the mine car is required to be pulled to the working surface by the traction winch through the inclined drift rail, and then the mine car is pulled to exit the working surface by the traction winch along the inclined drift rail after being filled, and is transferred to the rail transportation main drift to the wellhead.
But in the process of conveying the traction mining truck to the wellhead, tunneling work is continuously carried out, so that produced gangue is not transported, a large amount of gangue can be accumulated at the tunneling working face, the tunneling working face is caused to stop for waiting for transportation and cleaning of redundant gangue, tunneling operation cannot be carried out stably and continuously, and tunneling efficiency is low.
To this end, my company has proposed a new gangue discharge system, as shown in fig. 2: a belt conveyor is arranged on a tunneling working face, a gangue sliding small well is arranged between track conveying lanes at the lower layer and below the tail part of the belt conveyor, a shaft is arranged in the gangue sliding small well, gangue produced on the tunneling working face is conveyed into the track conveying lanes at the lower layer through the gangue sliding small well, and then the gangue is conveyed to a wellhead by a conveying mine car in the track conveying lanes at the lower layer, so that no gangue is accumulated on the tunneling working face at the upper layer, and continuous operation of tunneling and gangue discharging is realized; because there is not the shutoff structure in pit shaft bottom, the waste rock can incessantly fall downwards, and the transportation mine car fills the back, and the waste rock of whereabouts can scatter to ground, consequently, for convenient control waste rock unloading, need a device that can control the unloading at any time, and this provides a novel unloading spout for colliery waste rock emission.
