Description

technical field [0001] The invention relates to a grouting equipment, in particular to a grouting equipment applied to overlying rock isolation. Background technique [0002] At present, high-pressure grouting is used to fill the excavated overburden layer separation area through ground drilling, and a compaction support area with a certain width is formed in the middle of the working face, and the stability of the key layer structure of the overlying rock is controlled by combining the compaction area and the isolated coal pillar. In order to reduce surface subsidence and protect the surface from damage to farmland and structures within the coal mining area, this technology does not change the coal mining process, makes full use of existing roadways, and adopts green mining technology to recover the coal under the structure, which can be used The lower mining cost has achieved significant economic benefits, which is conducive to the succession of mine production.
