Product Features:

1. Low cost: The raw material cost is much lower than that of cement, which can significantly reduce the filling cost of mines, usually saving 30% -50% compared to using cement.
Good flowability: It can prepare high concentration and good flowability filling slurry, which is convenient for long-distance pipeline transportation and not easy to clog.
2. Moderate early strength: The strength development curve matches well with the mining process, meeting the necessary early support strength without increasing the difficulty of subsequent mining due to excessive strength.
3. Stable strength in the later stage: The strength continues to increase, forming a long-term stable filling body that effectively supports the formation.
4. Low bleeding rate: It can reduce the segregation and bleeding of the slurry, and improve the homogeneity of the filling material.
5. Strong technical specificity: designed specifically for complex chemical environments in mines (such as acidic mine water), typically with better resistance to corrosion and sulfate attack.

Application Scope:

Backfilling adhesive material for mines is the core material of modern green mining technology, mainly used for:
Backfilling of metal mine goaf: backfilling of underground mining goaf in iron, gold, copper, lead and zinc mines, etc.
Coal mine subsidence control: used to fill the underground voids formed after coal mining to prevent surface subsidence.
Tailings consolidation and backfilling: Mixing the tailings produced after beneficiation with cementitious materials to make filling slurry and backfilling underground is one of the safest and most environmentally friendly ways to dispose of tailings.
Ecological restoration of abandoned mines: Backfilling abandoned mines left over from history to lay the foundation for subsequent land reclamation and ecological reconstruction.
