Abstract

The invention discloses a comprehensive treatment system for coal and gangue underground in coal mines, which solves the problems of separation of coal and gangue and utilization of gangue. The connecting lane of the top chamber, the air inlet hole and the track alley, the comprehensive gangue body warehouse includes the gangue bin, the gangue bin and the filling gangue bin. Underneath, the gangue bin roof chamber connects the gangue bin and the gangue bin entrance, and the outlets of the gangue bin and gangue bin are set on the top of the gangue bin connection lane, which connects the two track lanes and fills the gangue bin The entrance is set in the gangue storage lane, the outlet is set in the filling lane, and the air inlet connects the filling lane and the gangue bin lane. The underground coal and gangue comprehensive processing system of coal mine also has the advantages of strong gangue storage and transportation capacity, alleviating the transportation conflict between coal and gangue, improving coal quality, and collecting and utilizing gangue.

Description

technical field [0001] The invention relates to a coal and gangue comprehensive treatment system, in particular to a coal and gangue comprehensive treatment system applied in underground coal mines and a construction method of the coal and gangue comprehensive treatment system. Background technique [0002] During the fault-crossing period of the coal mining face in the coal mine and during the excavation of the rock roadway, the gangue produced and the gangue produced by the excavation of the roadway are generally mixed into the coal transportation system and lifted from the main shaft to the ground. At present, the washing capacity of ground coal washing plants in coal mines has generally become saturated. These factors have seriously restricted mine coal output and coal quality, and affected the improvement of coal mine economic benefits. In addition, when coal mines carry out underground filling and mining, there may be insufficient amount of gangue, and it is difficult ...
