矿床的地质勘探历来套用某种固定的勘探网度。即根据不同的矿床和对其勘探的难易程度,分为不同的勘探类型,沿矿体的走向和倾向按一定的间距布置探矿工程,求得相应级别的储量。本文主要讨论求得C 级工业储量的勘探网度。勘探工程间距通常用四种方法确定:(1)类比法;(2)稀空法;(3)直接确定法;(4)数理统计法。这些方法虽有其根据和优点,但也有它不可避免的缺陷和不合理性。由于实际矿床的复杂多样,一个矿床勘探网度的选择既不宜套用任何一种类型的矿床勘探方案,也不可能在同一矿区施工大批探矿工程进行网度的优选。
Geological prospecting has always been to apply a certain degree of exploration network. That is, according to different deposits and their ease of exploration is divided into different types of exploration, along the ore body trend and tendency of the layout of the exploration project at a certain spacing, obtain the appropriate level of reserves. This article mainly discusses the level of exploration for obtaining Class C industrial reserves. The spacing of exploration projects is usually determined by four methods: (1) analogy; (2) levitation; (3) direct determination; (4) mathematical statistics. Although these methods have their basis and advantages, but it also has its inevitable defects and irrationality. Due to the complexity and variety of actual deposits, the selection of one exploration deposit should not be applied to any type of deposit exploration program, nor should it be possible to construct a large number of prospecting projects in the same mining area to optimize the degree of the network.
