黔西北猪拱塘铅锌矿床品位-吨位模型探讨
Discussion on Grade-Tonnage Model of Zhugongtang Lead-Zinc Deposit in Northwest Guizhou Province
摘要
Abstract
The grade-tonnage model of ore deposit is a quantitative model describing the variation range and frequency distribution of grade and tonnage of a certain type of ore deposit,which is an important part of mineral resource potential evaluation.This article selects Zhugongtang super-large lead-zinc deposit of the northwestern Guizhou as the research object,on the basis of the comprehensive exploration data,using SPSS and Excel software to process and analyze the frequency distribution of grade-tonnage data of 153 ore block section(minimum research unit)of Zhugongtang lead-zinc deposit in the northwest Guizhou and,then A P-P plot normality test is carried out,construct the grade model and tonnage model and grade-tonnage combined model.The results show that the grade model of Zhugongtang lead-zinc deposit in northwest Guizhou follows normal distribution,and the tonnage model follows lognormal distribution.The distribution characteristics of lead-zinc grade and tonnage in the deposit are summarized by the model,which can provide guidance for future prospecting and prediction work of the deposit.关键词
