摘　　要：文章在认识、总结杨金沟白钨矿床基本地质特征基础上,重点讨论了该矿床勘查类型主要参数与新、老规范的对比,提出杨金沟白钨矿床勘查类型为第二勘查类型以及不同勘查阶段的合理勘查工程间距,改变了在勘查初期套用钨矿第三勘查类型网度和工程间距的认识,对近几年来杨金沟白钨矿床地质勘查工作布署、勘查进展以及勘查资金有效合理的投入产生了较大改变。Based on understanding and summarization regarding the basic geological characteristics of the Yangjingou scheelite deposit, this paper mainly discusses the major prospecting parameters, contrasts the new models with the previous ones. It is suggested that the prospecting type for the depos- it is Type II, and some reasonable engineering space separations at different prospecting stages should be set. These change the misunderstanding that prospecting for the Yangjingou scheelite deposit at the early stage use indiscriminately grids and the engineering spaces suitable to the Type Ⅲ of the tungsten deposit. Therefore, the result is helpful to arrange workload, control engineering progress, and reasonably fund exploration.
