我国目前开采的脉金矿床中,中小型矿床占大多数.而中小型矿山的产量在全国总的黄金产量中所占的比重大约在40%左右.因此,中小型黄金矿床的地质勘探程度,不但直接影响矿山的经济效益,也对发展我国黄金生产有重要作用.地质勘探网度过密,则会影响或延长勘探时间,增加勘探成本和勘探费用.反之、则会遗漏矿脉或歪曲矿脉的本来面貌,说成资源不清,同时也会增加矿山的生产探矿费用,从而降低生产矿山的经济效益.为此,我们仅就辽宁省凌源县金矿的具体地质条件,探讨一下中小型黄金矿床的勘探程度问题.
Among the pulse-gold deposits currently mined in our country, the small and medium-sized deposits account for the majority, while the output of small and medium-sized mines accounts for about 40% of the total gold output in the country Therefore, the degree of geological exploration for small and medium-sized gold deposits, Not only directly affects the economic benefits of mines, but also plays an important role in the development of China’s gold production. If the geological exploration network is too dense, it will affect or prolong the exploration time and increase exploration costs and exploration costs, otherwise, it will omit or distort the veins Originally, said that the resources are unclear, but also increase the mine production prospecting costs, thereby reducing the economic benefits of producing mines.To this end, we only Lingyuan County, Liaoning Province, the specific geological conditions of gold to explore small and medium-sized gold Exploration degree of the deposit.
