摘要
赣南是风化壳离子吸附型稀土矿床的发现地和集中分布区,在勘查评价此类矿床时,稀土矿产勘查规范中主要是采用小圆井作为主要勘查手段开展地质评价,但在长期的勘查开发实践中常采用洛阳铲施工取样进行勘查。本文通过研究采用小圆井和洛阳铲两种施工取样手段勘查评价同一矿块(矿体形态、品位、厚度均相同的矿床),从对资源储量估算的影响程度入手,对洛阳铲与小圆井两种施工取样手段在风化壳离子吸附型稀土矿床勘查评价中的应用进行了分析对比,表明洛阳铲施工比小圆井施工更具操作简便、成本低、安全快速、不污染环境的优势。
Southern Jiangxi Province is the discovering and concentrated area of weathering crust iron- adsorption type REE deposits. According to Specification for Rare Earth Mineral Exploration, small well is the main recommended prospecting method during exploration and evaluation. However, Luoyang shovel is common adopted in the practice. Based on influence on resource estimates of one block with the same form, grade, and thickness, the two types of sampling methods using Luoyang shovel and small well in exploration and evaluation of weathering crust iron-adsorption type REE deposit are contrastively analyzed. The result suggests that Luoyang shovel possesses advantages of easy operating, low cost, safety, speediness and environment friendly,compared with small well.
