    Through the study of the relations between annual explorated reserves and a certain year of a lead and zinc deposit in Yunnan Province,the paper simulates the optimum correlation curve on computer.The time-velocity method was creat- ed firstly by D.F.Hewett in 1929.It is based on the historical data of a deposit without concerning on the real geological conditions and may provide a prediction on the future state of mineral resources.Firstly,the method needs a data prepara- tion that is to get annual explorated reserves year by year through the whole exploration period and then to draw a disper- sal map.Secondly,the method needs to find a optimum curve and acturally find s-shaped curve is optimum.Finally,the selected simulated curve shall be checked and explained. The paper use a lead and zinc deposit in the Yunnan province as an example to predict its amount of mineral re- sources and obtained very effectivel results.The calculated correlation coefficient of total annual explorated reserves and years are O.9.

    Abstract

    河南省铅锌资源短缺。“七五”期间,省厅地调二队在汝阳县付店地区开展激电法找铅锌矿工作,发现了一批有找矿意义的异常和多处找矿有利地段。地质、物探紧密配合,查证异常见矿率达90%,已有两处铅锌矿点扩大为中型矿床。

    In order to make full use of the limited lead and zine resource,stablize the grade of ores supplied, improve the mine's economic efficiency, through many years of ore mixing practice.a general technical management model is concluded as follows:Geological instruction for stoping:on-site management of ores (underwell ore ex-tracting+ore mixing);stablize the grade of ore supplied.This Management model is valued for popularization and application.

    为充分利用有限的铅锌资源,稳定铅锌供矿品位,降低生产成本,提高矿山经济效益,经过多年配矿实践,总结出一个普通的稳定供矿品位技术管理模式即回采作业地质指导→现场矿石管理(井下出矿管理+配矿)→稳定供矿品位,此管理模式具有一定的推广应用价值.
