Problems solved by technology

[0003] "Three-down coal pressing" refers to coal pressing under buildings, railways, and water bodies. The mine is increasingly affected by the "three-down coal pressing". The cost is gradually increasing, and after the gangue is lifted, it not only increases the ground occupation area, but also increases the pollution of solid waste, which affects the working and living environment

Embodiment

[0039] A construction method for an intensive underground coal-gangue separation system, comprising the following steps:

[0040] 1. Construction of gangue transportation system

[0041] S1. Open the door of the self-separation yard and construct the roadway that runs through the raw coal transportation belt lane 14. The width of the laneway is 3.6m and the height is 3m, forming the clean coal belt lane 13;

[0042] S2. Construction of the washing chamber at the end corresponding to the clean coal belt roadway 13 in the separation and transportation yard, excavation in layers during construction, the width of the roadway is 6.3m, and the height is 7.1m, forming a clean coal processing area 18;

[0043] S3, at the end of the clean coal treatment area 18, push the construction at 0°, the width of the roadway is 6.3m, and the height is 4m, forming a crushing and separation area 17;

[0044] S4. When the construction reaches the position of 7.6m in step S3, push the construction on...

Abstract

The invention discloses an intensive underground coal and gangue separation system and a construction method, and belongs to the technical field of coal mine underground coal and gangue separation andfilling. The intensive underground coal and gangue separation system comprises a coal and gangue separation system, a coal and gangue transportation system, a gangue crushing system and a filling material storage system; the coal and gangue transportation system comprises a raw coal transportation belt main roadway, a washing belt roadway, a slack coal belt roadway, a clean coal belt roadway, a transfer belt roadway and a gangue warehousing roadway; and the coal and gangue separation system comprises a roller screen, a jaw crusher, a pulse jigger, a clean coal bucket elevator and a gangue bucket elevator. According to the construction method, the clean coal belt roadway, a clean coal treatment area, a crushing separation area, the transfer belt roadway, a pre-crushing area, the washing belt roadway and the slack coal belt roadway are sequentially arranged. The system and the method can simplify a gangue lifting system, are beneficial to safety management and cost reduction, and have the advantages of reducing occupied land, reducing solid waste pollution, promoting coordinated development of resource development and ecological environment and the like.

Description

technical field [0001] The invention relates to the technical field of underground coal and gangue separation and filling in coal mines, in particular to an intensive underground coal and gangue separation system and a construction method. Background technique [0002] Coal is the main solid fuel and a kind of combustible organic rock. It is formed by the luxuriant plants growing in a certain geological age, gradually accumulating into thick layers in a suitable geological environment, and buried in the bottom of the water or in the sand, and formed after a long geological age of natural coalification. A coal mine is a reasonable space excavated by humans when excavating geological layers rich in coal, usually including roadways, shafts, and mining faces. It is an area where humans mine coal resources in coal-rich mining areas, generally divided into underground coal mines and open-pit coal mines. When the coal seam is far away from the surface, it is generally selected to...
