由于砂金矿的勘探与开采具有周期短、投资少、经济效果好的优点,同时,我国的幅员辽阔,可供黄金地质勘探的河流、水系较多,而且也还有一定数量的滨海砂矿可以进行工作,因此,近几年来黄金地质勘探工作得到了应有的重视,也有了一定的发展。但砂金矿钻探目前钻进工艺和钻探设备都比较落后,生产水平和砂钻质量都较低,远远适应不了四化建设的需要,应尽快改变这种落后面貌,现就砂金矿钻探的特点及现状,谈几点意见。
Because of the exploration and exploitation of gold and gold deposits with short cycle, low investment, good economic effect, at the same time, China’s vast territory, for gold geological exploration of rivers, more water systems, but also a certain amount of coastal sand ore Therefore, in recent years, gold geological exploration work has been given due attention, but also has some development. However, gold and gold mine drilling technology and drilling equipment are currently relatively backward, the level of production and quality of sand are lower, far from the four modernizations can not meet the needs of such backwardness should be changed as soon as possible, is now gold and gold drilling The characteristics and status quo, talk a few comments.
