Problems solved by technology

If it is not effectively resolved, in addition to causing tension in the mining area, the service life of the mine will also be greatly shortened, and it will face the serious problem of premature scrapping
This will not only cause a great waste of resources for the country, but also bring employment pressure to mines and other social problems
Mining 60m, leaving 60m, the degree of damage to ground buildings after mining is at level II, but the comprehensive recovery rate is less than 50%, and the loss of coal resources is serious

Abstract

The invention provides a device for filling gangue. The device comprises a bing-hole (101), a gangue bin (104), a pulverizer I (11), a conveyer and a gangue filling hydraulic support (23), wherein the gangue bin (104) is arranged in a stowboard (102); the bing-hole (101) communicated with the gangue bin (104) is arranged on the ground; the pulverizer I (11) is arranged on the ground; the pulverizer I (11) is installed to be connected with the gangue bin (104) through the bing-hole (101); the stowboard (102) is provided with the conveyer and the gangue filling hydraulic support (23); the gangue filling hydraulic support (23) is arranged on a filling operation surface; and the gangue bin (104) is installed to be connected with the gangue filling hydraulic support (23) through the conveyer, thus the gangue pollution is eliminated and the exploitation recovery rate can be improved.

Description

[0001] 1. Technical field [0002] The invention relates to a device for filling mine tunnels, in particular to a device suitable for filling tunnels with gangue. 2. Background technology [0003] After using the conventional full caving method to manage the roof mining, it will cause surface subsidence and damage. In most coal mines in my country, three-down coal mining problems are involved, and some coal mines have affected the normal connection and safe mining of the mine, and even caused ground damage. The relationship between enterprises is tense, so gangue filling is the key to solving these problems, and it is also the development trend of green mining. During the coal mining process, a large amount of gangue is discharged to the ground, which not only occupies land but also causes pollution. In addition, gangue dumps on the ground are likely to cause gangue dump accidents . At the same time, the mining space in the underground mining face is managed by the all-caving...
