Problems solved by technology
Especially in rocky roadways, if no grouting operation is carried out, it will be easily weathered after excavation, resulting in failure of roadside anchor net support, prominent roof drop problem, increased safety hazards, and increased difficulty in handling
Therefore, it is necessary to control the weathering of roadway rocks and the reduction of support strength by timely grouting
This will involve the continuous supply of a large amount of shotcrete materials, which is quite difficult for general mines, especially for mines with relatively backward auxiliary transportation systems and insufficient transportation capacity.

The invention designs a delivery system and particularly relates to a long-distance guniting material delivery system which is simple and reasonable in structure and capable of realizing long-distance guniting delivery. According to the technical scheme, a bottom discharge outlet of a ground dry material storage bin is communicated with a feed inlet of an air delivery pump, a discharge outlet of the air delivery pump is communicated with a chamber storage bin, the chamber storage bin, an agitator and a wet material delivery pump are mounted in an underground chamber, a bottom discharge outlet of the chamber storage bin is communicated with the agitator, a discharge outlet of the agitator is communicated with the wet material delivery pump, a discharge outlet of the wet material delivery pump is communicated with a wet material storage bin, and a wet guniting machine is mounted on a discharge outlet of the wet material storage bin. The long-distance guniting material delivery system is widely applied to concrete guniting and delivery.
Description
technical field [0001] The invention designs a conveying system, and in particular relates to a long-distance conveying system for grouting materials. Background technique [0002] With the continuous shortening of the infrastructure construction period of large-scale modern mines, the length of open roadways is continuously lengthened, and the requirements for support strength are getting higher and higher. Bolt-shotcrete support has gradually become the first choice for permanent roadway support in various mines. Especially the rocky roadway, if the grouting operation is not carried out, it will be easily weathered after excavation, resulting in the failure of the roadside anchor net support, the problem of the roof falling bag is prominent, the safety hazards increase, and the processing difficulty is increased. Therefore, it is necessary to control the weathering of roadway rocks and the reduction of support strength by timely grouting. This will involve the continuous ...
