Embodiment

[0062] The gangue is transported to the warehouse roof communication lane 2, and the dumper 23 removes impurities such as gangue, long anchor rods, and road logs larger than 500mm×500mm in the gangue, and is transferred to the gangue through the shuttle 22. Primary crushing is carried out in the double-toothed roller crusher 21, so that the size of the gangue is not greater than 80mm×80mm, and it is sent into the gangue bin 1 for storage.

[0063] When solid filling is performed on the working face 6 to be filled, the gangue is quantitatively sent to the working face 6 to be filled through the weighing type two-way belt 32 from the gangue bin 1 through the centralized track roadway belt 33 The middle and lower parts are filled accordingly to the upper end of the working face 6 to be filled, and compacted with a compactor.

[0064] When the two ends of the working face 6 to be filled are filled with paste, the gangue is quantitatively sent from the gangue bin 1 to the double-ro...

Abstract

The invention provides a solid and paste combination filling system. The solid and paste combination filling system comprises a waste rock bin, a bin top connection roadway, a concentration track roadway, a filling station, a pipeline transferring device and a to-be-filled working surface. According to the solid and paste combination filling system and a filling method which are provided by the invention, the to-be-filled working surface is filled in a segmented mode; the middle segment, easy to fill, of the to-be-filled working surface is subjected to solid filling, and a worked out section of the working surface can be subjected to solid filling quickly; the two ends, difficult to fill, of the to-be-filled working surface are subjected to paste filling, and the defect that the two ends are not filled enough through solid filling is overcome; in addition, the worked out section is filled more compact, and the ground surface settlement amount is further decreased; meanwhile, the problems that gob-side entry retaining cannot be conducted and Y-shaped ventilation cannot be achieved through solid waste filling are solved.

Description

technical field [0001] The invention relates to the field of coal mining filling equipment, in particular to a solid paste combined filling system. Background technique [0002] my country's per capita coal resources are relatively small, and the "three strikes" have a large amount of coal pressure, which affects the normal production and continuity of mines; conventional caving coal mining methods cause surface subsidence and groundwater and aquifer damage, resulting in damage to surface buildings; Gangue is directly dumped and stored, occupying land and polluting the environment. These problems urgently need to be solved through technological innovation of filling and mining. [0003] At present, as the profits of the coal industry decline, reducing production costs is the general trend, and using coal gangue as filling material is the best way to reduce costs. However, all coal mine filling mining enterprises use a single filling method, such as solid gangue filling mini...
