Common equipment of mining enterprises——mine sealer

Detailed description

Mine sealers often appear in the mining industry, because mine sealers can effectively help enterprises reduce risks and reduce accidents. Ensure the production environment of the enterprise and the health of the workers. So today we come to understand the working principle of mining hole sealer.

The working principle of the mining hole sealer is: connect the grouting tube of the product with the grouting pump, and the grouting slurry enters the grouting tube and the expansion bag through the grouting pump. Sealed; when the grouting pressure reaches 0.6Mpa and 1.2Mpa: the two blasting valves in the middle successively blast. The sealing liquid plugs the coal holes and intermediate cracks, and connects the gas drainage pipeline through a gas injection pipe to discharge gas.



1. Sealing automation. The hole sealer is fed into the hole, and only the grouting can be started to realize the automatic hole sealing of the whole hole, which greatly reduces labor intensity and improves work efficiency.

2. Active support. After the grouting, the pouch can effectively support the borehole, so that a high stress area is formed around the borehole of the sealing section, and continuous cracks can be created after the hole is sealed to form an air leakage channel.

3. Pressure grouting. The pressurized grouting pressure reaches 3.0 trillion torr, which can make the hydraulic pressure of the grout enter the borehole wall cracks, seal the cracks around the borehole, reduce its permeability, and play a role in blocking the initial leaking channel.

4. Adjustable length. The length of the sealer can be customized according to the actual length of the borehole downhole.

5. Advanced technology. "Two plugs and one injection" with pressure grouting sealing technology, advanced technology, good sealing effect.

Through the brief introduction of the mining hole sealer, I believe that everyone has a certain understanding of it. In the mining industry, the frequency of dangerous accidents is very high. Therefore, it is of great significance to protect the healthy working environment of mining enterprises.
