specific Embodiment

[0029] 1. Assisting the construction of the hand-selected gangue chamber in the strong tape lane.

[0030] Such as figure 1 , figure 2 , image 3 As shown, the gangue chamber is selected manually for the construction of the roof.

[0031] 2. The auxiliary strong belt has been modified, and a belt turning (reversing) device has been installed, and a hand-selected belt has been installed. The model is L=20m, B=1.0m, v=0.3m / s, P= 15kw.

[0032] 3. A simple screening device is installed at the unloading point to screen the coal.

[0033] 4. After the coal flow is screened, the coal gangue with particles smaller than 50mm directly enters the belt under the strong belt, and the coal gangue with particles larger than 50mm passes through the screening device and enters the hand-selected belt.

[0034] 5. Set up 4 people in each shift to manually select the gangue at the position of the hand-selected belt, and the selected gangue will be transported to the hand-selected gangue bi...

Abstract

The invention relates to a hand picking process with an underground powered rubber belt for waste rocks, comprising the following steps: (1) carrying out roof brushing construction in an underground powered rubber belt tunnel to build an underground chamber for waste rock hand picking; (2) carrying out downward construction at the rear part of the hand picking underground chamber to build a wasterock hand picking chamber; (3) installing a powered rubber belt turning device on the underground chamber for waste rock hand picking, forming unloading points, and installing a simple screening device at the unloading points; (4) installing a hand picking belt on the underground chamber for waste rock hand picking, and installing picking platforms on both sides; (5) screening coal flows conveyedto the unloading points, rotating large blocks of waste coal rocks and impurities into the hand picking belt, manually selecting the waste rocks, leading the picked waste rocks to be under the rotating carrying belt, leading the belt to enter the waste rock hand picking chamber, leading coal blocks and powdery coal to enter a powered belt conveyer on the bottom of the underground chamber for waste rock hand picking, and conveying the coal blocks and the powdery coal to a coal bunker of a concentrated mining area; and (6) leading the waste rocks in the waste rock hand picking chamber to enter a passing chamber, and directly conveying the waste rocks to an underground water rock filling system to prepare coal. The waste rocks are not on a well and are directly used for underground filling.

Description

technical field [0001] The invention relates to a coal mine raw coal gangue sorting process, in particular to an underground gangue manual selection process with strong adhesive tape. Background technique [0002] The general coal selection and selection process in all coal mines is as follows: After the coal is mined from the coal mining face, it is transported from the working face belt conveyor to the coal bunker in the mining area, and then transported to the underground centralized coal bunker through the mine's main transport belt conveyor. Enter the main shaft through the loader, lift from the underground into the raw coal preparation workshop, and pass through the raw coal grading sieve with a mesh size of 50mm for classification, and the underscreen (coal with a particle size of less than 50mm) enters the raw coal bunker through a belt conveyor; the overscreen ( Coal with a particle size greater than 50mm) is simply hand-selected manually to pick out large pieces of...
