摘　　要：地质勘探类型是科学地质调查和有效矿产资源评价的基础和前提。矿田是包含几个矿床的成矿空间,单个矿床的勘探类型不一定适用于矿田的地质勘探。文中遵循"成矿作用、地质工作程度和资源经济条件"的思路,探讨矿田勘探类型和分类问题。以地质勘查工作程度(地质调查或勘探报告所遵循的工作精度,即成果图件的比例尺为指标)和资源技术经济条件(各级资源储量的比例,并结合矿山生产规模为指标)为指标,作者建立"地质勘查程度资源经济条件"评价系统。经该系统的综合评价,研究预查矿田(Ⅲ)、普查矿田(Ⅱ)和详查矿田(Ⅰ)的基本地质勘探类型。矿田地质勘探类型的确定,为推动整装勘查区的找矿突破、制定勘查规划和勘探工作的投入提供了可参考的方法和思路。文中选择6个典型矿田,详细展示矿田勘探类型的评价过程和方法。The type of geological exploration is the basis of geological survey and mineral resources evaluation. Ore field is a mineralization space that contains several deposits, so the geological exploration for individual deposit is not suitable for ore field research work. To classify the type of geological exploration of ore field, this paper follows the research route of ＂mineralization, geological working level and economic and technological condition＂ to do the comprehensive assessment. This paper discusses the type of geological exploration in ore field and how to classify them based on the research program of ＂operating instructions for geological exploration in metallic ore field＂. This paper uses the geological working level （i. e. , the accuracy of geological survey or exploration report, which means using the plotting scale of the resulting map to be the index）, and resource technical and economic conditions （which means using the ratio of different levels of mineral reserves combined with mine productivity to be the index） to set up an evaluating system of ＂geological exploration level-resource and economic condition＂. After comprehensive evaluation, three geological exploration types were shown, they are pre-survey ore-field （ Ⅲ ）, general survey ore-filed （ Ⅱ ） and detailed survey ore-field（ Ⅰ ）. The determination of geological exploration type of ore-field provides referable methods and ideas to promote prospecting breakthrough in the packaged exploration area and to work out the exploration plan and the amount of workload. This paper selects 6 classic ore-fields to show the evaluation process and technical route in detail.
