| 中文摘要: |
| 内蒙古翁牛特旗硐子矿区铅锌矿床主矿体长3698 m,延伸695 m,平均厚度2.07 m,呈脉状,Ⅰ类勘查类型。近3年累计提交矿石量1171.92万t,铅金属量150 671 t,锌金属量306 969 t。文章分析了矿区大地构造位置,各矿体特征品位变化及厚度变化系数。研究了矿区的水文地质、工程地质及环境地质,依据矿床矿体分布特点及矿床水文地质条件,利用“大井法”进行了矿坑涌水量预测。根据矿体(层)围岩类型及矿石特点,采集矿区6组岩(矿)石进行力学实验,分析矿区矿层性质及稳固性。预测矿山开采对环境、生态影响程度。划分矿床开采技术条件类型,为矿山今后建设提供参考。 |
| 英文摘要: |
| The main ore body of Dongzi Pb-Zn deposit is the Vein deposit with the length of 3698 m, depth of 695 and average thickness of 2.07 m and classified as II prospecting type. We have submit ores of 11719200 tons, Pb mental volume of 150671 tons, and Zn of 306969 tons. In this paper, we analyses the tectonic background, variety coefficient of the grade and the thickness of the Dongzi deposit. The hydrogeology, engineering geology and environmental geology are also well studied. We deals with hydrogeological conditions and water filling conditions in the ore district and predicts the mine inflow by means of "big well method". According the geological condition, we selected 6 types of rocks and ore rock in district and measured their mechanical conditions which provided information for studying the stabilization of ore body. We predict the environmental and ecological effects of the mining, and classify the mining technical conditions, which will provided references for mine construction. |
