Product use: FKJW-50 / 2.0 mine hole sealer, used in coal seam borehole plugging, such as coal seam pressure measurement drilling, rock lane upward drilling, downward drilling, drilling in this coal seam, etc. The working principle of extraction and plugging: connect the grouting pipe of the product to the grouting pump, and the plugging slurry enters the grouting by the grouting pump.
FKJW-50 / 2.0 mining hole sealer is used for coal seam borehole plugging, such as coal seam pressure measurement drilling, rock lane ascending drilling, descending drilling, local coal seam drilling and other gas extraction and sealing Blocking works:
The grouting tube of the product is connected to the grouting pump, and the sealant slurry enters the grouting tube and the expansion bladder by the grouting pump. The bladder expands and the outer wall is sealed with the coal hole. When the grouting pressure reaches 0.6Mpa and At 1.2Mpa: the two blasting valves in the middle successively blast. The sealing liquid plugs the coal hole and the intermediate cracks, and connects the gas drainage pipe through the gas injection pipe to discharge the 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 the labor intensity and improves the work efficiency.
2. Active support. After the grouting, the pouch can effectively support the drilling, so that a high stress area is formed around the hole in the sealing section, and continuous cracks can be created after sealing, forming a leak 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 hole sealer can be customized according to the actual drilling length downhole.
5. Advanced technology. "Two plugs and one injection" with pressure grouting sealing technology, advanced technology, good sealing effect.
