摘　　要：地浸采铀目前基本限定在砂岩型矿床中,因此,圈定和评价此类资源就显得十分重要,不但需要制定可在实际中应用的规则,而且更需确定所使用的参数值,如矿体厚度、品位、密度、GT值等。美国在多年的实践中定义了探明资源、控制资源和推断资源以及证实储量和概实储量,推出了评价方法,制定了与其对应的勘探网度、钻孔见矿程度划定、不同参数计算处理的规则,特别是地浸铀矿山集中的怀俄明州,归纳出一套系统的地浸卷状铀资源的勘探和评价方法。Nowadays the in-situ leaching of uranium is basically restricted to sandstone deposit, therefore, the importance of delineation and evaluation of this type of resources is revealed, particularly at establishing rule that can be applied for determining the value of various parameters such as thickness of ore body, grade, density, GT and so on. The measured resources, indicated resources and inferred resources as well as proven reserve and probable reserve are defined in US based on many years＇ practice, the evaluation rule is presented, the spacing of exploration grid related to roll type uranium resources is determined, the classification of drilling hole intercepting uranium mineralization and processing regulation for different parameters are introduced, especially in Wyoming where in-situ leaching uranium mines are concentrated and a series of systemic exploration and evaluation procedures of roll type uranium resources for in-situ leaching are concluded.
