内蒙古上碧流台矿区铅锌矿矿体地质特征及矿床开采技术条件研究

Study on geological characteristics and mining technical conditions of lead-zinc deposit in Shangbiliutai Mining Area,Inner Mongolia

分析了矿区地质,主要研究了地层、侵入岩、构造和矿区地球物理特征。基于此,分析了矿区矿体地质特征,通过对矿床类型、成矿条件、控矿因素的分析研究,认为本区矿床属于中低温火山热液型脉状铅锌矿床。根据北西向构造延伸特征,结合本区矿脉分布规律及勘探经验,在矿区的西、南面开展找矿工作,前景可期。研究了矿床开采技术条件,得出矿区开采技术条件类型为以水文地质、工程地质、环境地质复合问题为主、开采技术条件中等的矿床,即Ⅱ-4型。研究为矿山综合开发、充分利用矿产资源提供了可靠依据。

The article analyzed the geology of the mining area,mainly studies the strata,intrusive rocks,structures and geophysical characteristics of the mining area.Based on this,the geological characteristics of the ore body in the mining area are analyzed.Through analysis and research on deposit types,mineralization conditions,and ore-controlling factors,it is believed that the deposit in this area belongs to a medium to low temperature volcanic hydrothermal vein type lead-zinc deposit.According to the tectonic extension characteristics of NW trending,combined with the distribution law of ore veins and exploration experience in this area,ore prospecting work is carried out in the west and south of the mining area,and the prospect is promising.The mining technical conditions of the ore deposit are studied,and it is concluded that the type of mining technical conditions in the mining area is typeⅡ-4,which is mainly composed of hydrogeology,engineering geology and environmental geology,and has moderate mining technical conditions.The research provides a reliable basis for comprehensive mine development and full utilization of mineral resources.
