划分矿床勘探类型及对有用组分分布很不均匀、非矿部分无法直接圈出的矿床进行储量计算时,往往引入含矿系数这一概念.含矿系数是矿床、矿体、矿段或块段内有工业价值的矿化部分与整个矿床、矿体、矿段或块段的长度、面积或体积之比.用长度之比确定的含矿系数称为线含矿系数;用面积之比确定的含矿系数称为面含矿系数;用体积之比确定的含矿系数称为体含矿系数.体含矿系数最具代表性,但勘探中绝大多数情况下,不能直接确定.而沿走向,倾向或厚度方向的线含矿系数及走向或倾向横断面的面含矿系数较易确定.确定某一方向线含矿系数时,一般就用这个方向的线含矿
It is often introduced into the concept of ore-bearing factor when the types of deposits are classified and the distribution of useful components is not uniform, and the reserves that can not be directly encircled by the non-ore part are often calculated.The ore-bearing factor is the deposit, ore body, The ratio of the mineralized part of an industrial value to the length, area or volume of the entire deposit, ore body, ore section or block, which is determined by the ratio of lengths, is called the line mineralization factor; The determined ore-bearing factor is called the surface ore-bearing factor, and the ore-bearing factor determined by the volume ratio is called the body-contained factor.The body’s ore-bearing coefficient is the most representative, but it can not be directly determined in the vast majority of exploration situations. The line mineralization along the strike, dip or thickness direction and the facies-bearing factor of the strike or dip cross-section are easy to determine. When determining the ore-bearing factor of a directional line,
