矿山地质工作者在计算矿床储量时,必须知道它的各项工业指标.在中南脉状钨矿矿床中常需要的是边界品位、最低工业品位、公尺百分比、最小可采厚度.应当指出,笔者认为最小可采厚度在脉状钨矿矿床中是没有实际意义的.因为有些矿脉厚度虽小,而有用组分特别富集,有可采价值,因此以改用设计最小采幅较为合理.并依此指标作为使用最低工业品位或公尺百分比圈定表内矿量的界线.脉宽大于此指标用最低工业品位来圈定表内矿量,反之,则用公尺百分比圈定之.
Mine geology workers in the calculation of ore reserves, we must know its various industrial indicators in the Central South vein tungsten ore deposits often need is the grade of the border, the lowest industrial grade, the percentage of meters, the minimum recoverable thickness.It should be noted that the author It is considered that the minimum recoverable thickness is of no practical significance in the vein-like tungsten ore deposits, because some of these veins are small in thickness and the useful components are particularly enriched and have recoverable values, so it is reasonable to switch to designing the minimum amplitude. Use this indicator as a margin of delineation of the amount of mineral in the table using the lowest industrial grade or the percentage of the meter Pulse width greater than this indicator Use the lowest industrial grade to delineate the amount of mineral in the table or vice versa.
