Description

Technical Field

[0001] The utility model belongs to the technical field of grouting, in particular to a grouting device used for water treatment of mine bottom plates. Background Art

[0002] Mine floor water management refers to the act of treating and controlling mine floor water to reduce the flow of water into the mine, prevent mine bottom collapse, and improve production efficiency and production safety. Floor water refers to the general term for the bottom stratum aquifer or downwelling water in mining mines such as coal mines, metal mines, and salt mines. It is the most common water in mines. Since there are usually defects such as cracks and voids in the mine floor, water flows into the mine, seriously affecting the production and safety of the mine. Therefore, grouting technology is needed to inject grouting materials into the defective parts of the mine floor to fill the gaps and voids and form a plugging layer, thereby reducing the flow of water into the mine and preventing bottom collapse.

[0003] However, the existing grouting device still has shortcomings in use. After the material slurry is stirred, if the slurry is very viscous, it is inevitable that part of the slurry will stick to the surface of the stirring shaft and the inner wall of the stirring kettle. The slurry sticking will cause part of the slurry to be unable to be fully mixed and stirred during the stirring process, reducing the utilization rate of the slurry, resulting in a waste of slurry resources and an increase in production costs. Therefore, we propose a grouting device for mine floor water treatment to solve the above problems. Utility Model Content
