Description
Technical Field
The invention belongs to the technical field of preparation and application of high polymer materials, and particularly relates to a single-component rapid water plugging material for a coal mine, and a preparation method and a use method thereof.
Background
The water damage of the coal mine affects the progress and quality of mine engineering construction, worsens the labor environment of workers, increases drainage facilities and drainage cost of the mine, brings unsafe factors to coal mine production, even causes well flooding accidents, thereby causing great loss of life and property, and has very important and very urgent practical significance for preventing and treating the coal mine. Grouting and water plugging are one of important methods for preventing and controlling water damage of a mine, and the method has the obvious advantages of reducing the drainage burden of the mine, saving drainage electricity, reducing the cost per ton of coal, improving the working efficiency and quality, reinforcing the weak sections of a roadway, reducing the water inrush probability and prolonging the service life of the mine.
At present, most of the water plugging and grouting materials for coal mine roadways are selected from cement type grout materials or polyurethane type grout materials. The cement-based slurry has the main advantages of low cost and wide material source, but the cement-based slurry is easy to shrink after being hardened to generate fine cracks, the cracks are gradually enlarged under the hydraulic flushing, the water plugging effect is not ideal, and the cement-based slurry is a granular material and is difficult to press into the fine cracks, so the application range of the cement-based slurry has certain limitation; in addition, because of the slow curing speed, a large amount of gushing water in an emergency cannot be treated. The polyurethane slurry has strong adhesive force to materials such as coal rock mass and the like, has excellent performances such as corrosion resistance, wear resistance, impact resistance and the like, and has adjustable curing speed. However, the existing polyurethane water shutoff materials mostly adopt a two-component design, although the performance is good, special two-fluid grouting equipment is needed for operation during construction, the operation process is complex, and the treatment of sudden water burst cannot be finished particularly under the limitation of the grouting equipment under severe working conditions. The two-component design requires more raw materials, which results in complex processing technology and higher preparation cost. In addition, the foaming speed of the two-component polyurethane water plugging material is generally low, and the foaming curing time of the functional material is as long as 1 minute as in Chinese invention patent with publication number CN113621128A and patent name 'safety type phenolic resin modified polyurethane functional material and preparation method thereof'; the gel time of the Chinese invention patent with the publication number of CN105504202B and the patent name of 'an in-situ synthesized controllable nano-silica reinforced hydrophilic polyurethane grouting water shutoff material and a preparation method thereof' is about 20-30 seconds, and the prior art disclosed by the above patent is obviously not suitable for treatment of sudden water inrush accidents.
In summary, when a sudden flood occurs underground, if the water inflow is too large, the water plugging material in the prior art cannot be foamed and solidified, i.e. washed away by water flow, and the purpose of plugging water cannot be achieved. Therefore, in practical use, how to put and fix the water plugging material in combination with the emergency safety facility to achieve an excellent water plugging effect is also one of the technical problems that the technical personnel in the field need to solve urgently.
