摘　　要：引入矿化度的概念,=(矿体长度)·(平均厚度)·(平均品位),计(A)ALMC算并介绍了芙蓉矿田锡矿化强度的垂直分布特征,指出锡矿化集中分布在上、中、下个平台3(～、～、-～标高段),并对其在矿产资源量预测中的应用作了7001 300 m350700 m20350 m探讨,预测该矿田锡资源总量达×n102万t。At first introduce a new concept of mineralization degree (A), A=L (orebody's length)M ·(average thickness)C (average grade), and then the distribution characteristics of Sn-mineralized intensity were calculated and introduced. The result shows that Sn mineralization distribution centralizes in upper, middle and lower, 700~1,300 m, 350~700 m, -20~350m level respectively e.g.3 platforms. Its application in forecasting the quantity of mineral resources is also discussed. The total quantity of several million tons of Sn resources is forecasted.
