合理地选择矿床的勘探方法——布置勘探工程及其间距——是由许多因素决定的。其中最重要的是:矿体的大小、形状及其内部构造、倾角和矿石质量的稳定程度。虽然铁矿的自然类型是各种各样,但根据矿床本身的某些条件,可以将其分为五类,而每一类矿床,就其选择勘探方法的因素来讲都是相似的。第一类矿床是巨大的层状矿床,厚度很大,分布面积广(达几平方公里)。这类矿床成水平或缓倾斜产出,厚度稳定;脉石和不合乎要求的矿石夹层很少,而且可以将其从矿石中单独开采出去。
The rational choice of prospecting methods for a deposit - laying exploration projects and their spacing - is determined by a number of factors. The most important of these are: the size, shape and internal structure of the ore body, dip angle and the stability of the ore quality. Although the natural types of iron ore are varied, depending on the conditions of the deposit itself it can be divided into five categories, each of which is similar in its selection of exploration methods. The first type of deposit is a huge layered deposit, a large thickness, wide distribution area (up to a few square kilometers). Such deposits are leveled or gently inclined to yield stable thickness; gangue and undesirable intercalations are rare and can be mined separately from the ore.
