摘要
大部分化工原料矿床的工业指标主要采用品位和厚度两个指标。作者通过分析溧水爱景山锶矿品位指标和南京岔路口硫铁矿厚度指标使用中存在的问题,提出相应的修改意见。
The author considers that the grade and thickness indexes used in most of industrial chemical deposits should be mod- filed taking Aijingshan strontium deposit and Chailukou troliite deposit as two examples.The industrial grade,25 per tent which ia an industrial grade or index of expioilable grade,can be used to delimit and calculate the exploitable reserve of orebodies without boundary grade in Aijingshan strontium deposit.Other similar industrial chemical deposits can also be calculated by the method,Therefore,it can simplity the calculation and decrease woks.When to calcaulate lowest ex- ploitable thickness in industrial chemical deposits,the calculation method should be sellected in accordance with the prac- tice.Hence,the optimum date of reserve,higher calculation precision and less work quantity can be obtained.
