在储量計算工作中,目前对一般的大脈矿床与层状矿体,都已有一套比較成熟的經驗,但是对某些变化多端、产狀形态都比較特殊而少见的矿床类型,則缺乏一般可以通用的方法。江西某黑鎢細脈带矿床助为一例。该矿床有其独特的外表特征,虽然脈幅一般在0.2～0.4～0.8公尺,相似于一般大脈型矿床,但由于脈幅膨縮变化大,分枝复合频繁,特别是由于矿脈相当密集(脈間距多在0.3～0.8～2公尺),故不能套用一般大脈矿床的儲量計算方法。同时,以其矿脈忽分忽合,网絡密集的情况来看,又有似于細脈带
In the calculation of reserves, there are currently a relatively mature set of experiences in general vein-type deposits and layered ore bodies. However, for some types of deposits that have many changes and are in relatively special and rarefied forms, the general lack of general Can be common method. An example of a black tungsten vein pulse deposit in Jiangxi Province. The deposit has its unique appearance characteristics. Although the pulse amplitude is generally 0.2 ~ 0.4 ~ 0.8 meters, similar to the general vein type deposits, because of the large change of the amplitude of the pulse expansion, the complex of branching is frequent, especially because the vein is equivalent Dense (pulse distance of more in the 0.3 ~ 0.8 ~ 2 meters), it can not be applied to the general calculation of vein reserves method. At the same time, with its veins ignorance, network-intensive situation, there are similar to the veins
