辽宁宽甸富玉硅石矿矿床地质特征及开采技术条件分析

Geological characteristics and mining technique conditions of Fuyu silica deposit in Kuandian area of Liaoning province

富玉硅石矿床位于辽吉古元古代裂谷盆地中,矿体赋存于高家峪岩组变质陆缘碎屑建造中,矿体受榛子沟-宽甸南倾背斜北翼层间断裂控制,矿体呈似层状、透镜状产出,与围岩产状基本一致,倾向207°,倾角平均34°,平均真厚度为3.53 m,矿石平均品位SiO2 95.25%,Al2O 30.60%,Fe2O 30.19%,矿石品级以三级品为主,成因类型属于热液型脉石英矿床。矿床开采水文地质、工程地质、环境地质条件简单,为开采技术条件简单矿床。

The Fuyu silica deposit located in Liaoji paleoproterozoic rift basin,this deposit occurs in the Metamorphic marginal clastic rock formation of Gaojiayu formation in Liaohe group.The ore body is controlled by the interlaminar fault of the north wing of the Zhenzigou-Kuandian dip anticline,that is are layered and lenticular,and basically consistent with the occurrence of surrounding rock,tendency of 207°,inclination of 34°and average thickness of 3.53 m.The average grade is SiO295.25%,Al2O30.60%and Fe2O30.19%.As the same time,the natural grade is majorly three.The genetic type belongs to hydrothermal vein quartz deposit,the hydrogeological conditions,engineering geological and environmental geological conditions are simple,it belongs to the mining technology condition simple deposit.
