所謂勘探手段一般是指鑽探(包括岩心鑽探及水平鑽探等)山地坑道(包括平硐、石門、穿脈、沿脈、豎井、天井、盲井及探井等)以及槽探、剝土等工程。在地質勘探过程中,这些勘探手段的选擇與應用,主要是根据矿区的地質条件及自然条件等因素来决定的。正确地选擇和应用勘探探手段,不仅可以为国家节省人力和资金;更重要的是能在获得可靠的地質资料基础上向国家提交工业儲量。几年来。我們在对东北有色金屬矿床(主要是銅,鉛鋅矿床)的勘探过程中,已經积累了一些經驗,作者拟就此問題发表一些粗淺的意見,其目的是为了引起大家对这个問題的注意。一、东北有色金屬矿床一般特点
The so-called means of exploration generally refers to drilling (including core drilling and horizontal drilling, etc.) mountain tunnel (including adit, Shihmen, weaving veins, along the veins, shafts, patios, blind wells and exploration wells, etc.) and trench exploration, stripping and other projects. In the process of geological exploration, the selection and application of these exploration measures are mainly determined by the geological conditions and natural conditions of the mining area. Proper selection and application of exploration sections not only save the country manpower and capital, but more importantly, it can submit industrial reserves to the country on the basis of reliable geological data. Years ago We have accumulated some experience in the exploration of nonferrous metal deposits in the Northeast (mainly copper and lead-zinc deposits). The author intends to make some superficial comments on this issue in order to arouse people’s attention on this issue. First, the general characteristics of non-ferrous metal deposits in Northeast China
