AI Technical Summary
In the treatment of water inrush in inclined shafts of solid potash mines, the existing technology of direct grouting cannot achieve precise sealing. The aggregate filling is not dense, resulting in high grout consumption, poor sealing effect, and easy grout loss. It is difficult to adapt to the complex geological conditions of inclined shafts of potash mines.
The method of graded drilling construction and graded aggregate filling combined with grouting reinforcement is adopted. First, the dissolution space is accurately explored through through-tunnel filling boreholes and exploration and treatment boreholes. Coarse and fine aggregates are thrown in stages to form a dense skeleton. Then, the surrounding rock fissures are filled by grouting to form a stable water-blocking structure.
It achieves precise sealing of water inflow channels in inclined shafts of potash mines, reduces slurry consumption, improves the stability and durability of the water-blocking structure, avoids long-term expansion of water inflow channels, and ensures high construction safety.
