某“湿型”红土镍矿床开采实践

随着红土型镍矿选、冶技术的成熟以及硫化物型镍矿储量的严重不足,红土型镍矿床的开采吸引了人们的注意。然而"湿型"红土矿床由于其含水率高、地形起伏变化大、含砾率高、雨季强降水及持续大雾等众多因素的影响,开采极其困难。目前,"湿型"红土矿床的开采尚无成熟可供借鉴的经验。如何解决红土矿特有的特点所带来的回采困难,如何在技术上可行、经济上合理的原则下进行采矿,是"湿型"红土矿床开采所要首先解决的问题。开采实践中,通过不断的摸索和实践,总结出适合"湿型"红土矿床回采的宝贵经验。本研究着重介绍某"湿型"红土矿床之开采实践,介绍矿床剥离、开拓、回采、配矿等关键环节的现场经验,介绍设备的选型及采场所需的设备配置。

Mining Practice of a Humidified Laterite Nickel Deposit

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.
