坑道探矿是地質勘探的重要手段之一。它不仅能够正確地查明矿体的产狀、規模及質量变化情況,同时还有可能为今后生产所利用。在有色金屬、稀有金屬矿床,特別是在第三、四勘探类型矿床的勘探中,坑道探矿的作用尤为显著。但是坑探并不是地質勘探的唯一手段,它與其他勘探手段相比較,也還有其缺点。这就是一般掘进速度慢,技术設备复杂,掘进成本高。故在設計坑探中,除了根据不同矿床特性的地質要求加以适当地运用外,还必須注意施工技术上的可能性号經济上的合理性,这是采用坑探做为勘探手段的重要前提条件之一。回顧在第一个五年計划期間,冶金工业部的地質勘探部門共投入了100余万公尺的坑探工程量,其中絕大
Mine prospecting is an important means of geological exploration. It not only correctly identifies changes in the shape, size and quality of the ore bodies, but it is also likely to be exploited for future production. In non-ferrous metal, rare metal deposits, especially in the exploration of the third and fourth exploration type deposits, the role of excavation is particularly significant. However, pit exploration is not the only means of geological exploration. Compared with other exploration methods, pit exploration has its shortcomings. This is the general slow speed tunneling, technical equipment complex, high cost of driving. Therefore, in the design pit exploration, in addition to the geological requirements of different deposit features to be properly used, but also must pay attention to the possibility of construction technology, the economic rationality, which is used as an exploration pits exploration an important prerequisite one. Review During the first five-year plan, the geological exploration department of the Ministry of Metallurgical Industry invested a total of over 1 million meters of excavation works, of which vast
