A coal mine goblin filling system device

Abstract

The invention discloses a rapid and low-cost filling system device for underground abandoned roadways of coal mines. A first driven wheel, a driving wheel and a second driven wheel are mounted on theupper surface of a bottom frame in sequence from left to right; a horizontal conveyer belt is wound between the first driven wheel and the driving wheel; an inclined conveyer belt is wound between thedriving wheel and the second driven wheel; a loading hopper is mounted on the outrigger of the second driven wheel; the lower end of a crusher shell is connected with an unloading hopper; a filling bag is sleeved in a loading frame; the lower port of a pod passes through a control valve to be connected with a preheating supply pump; the preheating supply pump is connected with an injection pipe through a connection hose; a plurality of sprinkling holes are uniformly formed in the surface of the injection pipe; and the middle part of the injection pipe is movably hoisted on an upright tube through a hanging spring. The rapid and low-cost filling system device for the underground abandoned roadways of the coal mines is low in filling raw material cost and high in field packaging, stacking and filling efficiency, and is capable of improving the coal pillar recovery cleanliness.

Description

technical field [0001] The invention relates to the technical field of coal mine underground equipment, in particular to a coal mine goaf filling system device. Background technique [0002] At present, underground sorting and filling of gangue is the main technical path to realize green mining and scientific mining, which can minimize the impact of mining activities on environmental protection and has great development potential. At present, the underground mining has not realized the layout of all coal roadways. Excavating roadways in rocks and mining gangue coal seams will produce a large amount of gangue, which will pollute the environment when transported to the ground. In addition, various protective coal pillars are left in the underground production system. A large amount of coal resources are stranded and cannot be recycled; at the same time, due to production changes and contact roadways for recycling scrap coal, there are many empty roadways in the working face, a...

At present, the underground mining has not realized the layout of all coal roadways. Excavating roadways in rocks and mining gangue coal seams will produce a large amount of gangue, which will pollute the environment when transported to the ground. In addition, various protective coal pillars are left in the underground production system. A large amount of coal resources are stranded and cannot be recycled; at the same time, due to production changes and contact roadways for recycling scrap coal, there are many empty roadways in the working face, and the empty roadways are constantly exposed during mining. The underground gob filling system device has the urgency of research and development and the wide application
