Abstract: With the mature of laterite Ni deposits′ beneficiation and smelting technique and the serious lack of primary nickel reserves，mining of laterite nickel deposits attract the attention.However，due to the high moisture，rolling topography，high gravel contents，heavy rain and continuous fog in rainy season，it is most difficult to realize mining of humidified laterite Ni deposits.At present，there is no mature experience for reference in mining of humidified laterite Ni deposits.Problems that need to be solved first are how to solve the mining difficulty due to the characteristic of humidified laterite deposit and how to realize mining under the principle of technological feasibility and reasonable economy.The valuable experience that fits for mining of humidified laterite deposit is summarized according to continuous exploration and practice.The mining practices of humidified laterite Ni deposits are mainly introduced，including the field experiences in the key parts like stripping，development，mining and ore blending.The selection of mining equipment and the equipment configuration are present.
