| Abstract: | In view of the serious leakage caused by the corrosion and fracture of empty pipein the Ordovician limestone hydrological observation hole in Gaohe colliery,the author proposes the sealing technology of borehole water inflow and the corresponding grouting construction technique,whose 7-day underground test results show that the sealing grouting pressure reaches 6 MPa with 50 t grouting cement,and solidified cement slurry makes no water outflow when the grouting valve is opened. |
