AI Technical Summary

Problems solved by technology

Once foamed, it can no longer be moved, let alone sprayed at will, and the foaming lasts for a long time (more than 30 minutes), and it takes a long time (more than 60 minutes) to keep the original shape for a long time and uncontrollable
In addition, after foaming, neither agitation jet nor jet injection
However, coal seams of different shapes, gaps of different sizes, and roadways of different lengths in coal mines are impossible without flexible and controllable grouting materials.
[0006] Although cement foam, glass foam, etc. are inorganic materials, they cannot be moved freely after foaming. After being formed, they are hard block materials, which cannot be filled and injected into coal mine gaps like slurry. Problems such as injection plugging and filling reinforcement of voids cannot solve the problem of rapid filling of large roadways

Abstract

The invention provides an inorganic foaming filling and reinforcing composition for a coal mine as well as a using method and application thereof. The inorganic foaming filling and reinforcing composition for the coal mine can be used as a novel safe plugging and reinforcing material, is especially suitable for plugging and reinforcing of the coal mine, and is the best water-proof, fire-proof, gas-proof, collapse-proof and accident-proof material.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to an inorganic foaming filling and reinforcing composition for coal mines and its use method and application. Background technique [0002] In recent years, due to the needs of safe production in coal mines, researchers and enterprises have studied expandable foaming materials such as foaming, filling, and reinforcement for coal mines. The use of organic foaming materials in coal mines is still tentative. The organic foaming materials used are mainly polystyrene foaming materials, polyvinyl chloride foaming materials, polyurethane foaming materials, phenolic resin foaming materials and other polymeric organic materials. It is obviously very dangerous to use organic materials in coal mines to solve gas accumulation, prevent gas fires, block fire sources, prevent fires, and extinguish fires. First of all, during the foaming and curing process of organic materials, a high temperatur...
