通过主矿体下盘次级矿脉的构造岩相特征寻找新的盲小矿体

New Blind Small Ore Body Are Searched Through the Tectonic-Lithofacies Characteristics of the Secondary Veins in the Footwall of the Main Ore Body

白银矿田是我国重要的铜金属产地,经过半个多世纪的开采,资源已逐渐枯竭,一期采矿工程已近尾声,现已转入二期工程。面临矿石资源量较少、品位降低等问题。寻找新的资源储量是地质工作者的紧迫任务。因此主矿体边部盲小矿体开采显得意义更加重大。因矿体边部受控矿地质构造的影响,加之前期探矿工程有限,矿体边部盲小矿体未能得到有效控制。因此,为延长矿山的服务年限,认为应对矿床下盘进行任务探矿。

Silver Factory is an important copper metal producing area in China.After more than half a century of mining, the resources have been gradually exhausted.It is faced with the problems of less ore resources and lower grade.Searching for new resources and reserves is an urgent task for geologists.Therefore, the mining of blind small ore body in the edge of main ore body is more significant.Due to the influence of the controlled geological structure at the orebody edge and the limited pre-prospecting engineering, the blind small ore body at the ore body edge can not be effectively controlled.Therefore, in order to prolong the service life of the mine, the author has decided to explore the footwall of the deposit.
