Hole Sealing Technology and Technical Application of Drilling Engineering in Tailing Pond Exploration
By analyzing the geology and hydrogeological conditions of a tailings dam,drilling exploration of the accumulation dam was conducted to study its stress characteristics and macro-stability.At the same time,to prevent geological disasters caused by exploration drill holes turning into leakage paths that could harm the sur-rounding ecological environment,three sealing solutions were considered,including backfill sealing,karst cave drilling plugging,and cementation sealing.Sealing design was carried out to ensure the safety of the tailings dam as well as the efficient production of the mineral processing plant.
