凌源日兴金矿岩体结构面调查及特征分析

随着凌源日兴金矿采深不断增大,工程地质和矿体赋存条件越来越复杂,开展岩体结构面调查等地质工作十分必要。介绍了凌源日兴金矿地质条件和结构面调查方法,对不同中段岩体结构面进行了调查及统计,采用直方图及Dips软件生成的极点图、等密图、玫瑰图等方法对结构面调查数据进行了特征分析,确定了优势结构面的产状,并分析了岩体结构面对岩体质量的影响,为岩体工程稳定性分析评价及采矿方案设计提供了依据。

Investigation of the structural face of the rock mass in Lingyuan Rixing Gold Mine and its characteristics analysis

With increasing mining depth of Lingyuan Rixing Gold Mine,the engineering geology and ore body occurrence conditions in Lingyuan Rixng Gold Mine are becoming more complicated,making it necessary to carry out such geological work as investigation of the structural face of the rock mass. The paper introduced the method to investigate the geological conditions and structural face in Lingyuan Rixing Gold Mine,carried out investigation and did statistics of the structural face of the rock mass in different levels,analyzed the characteristics of the structural face investigation characteristics with the histogram and the point diagram,contour diagram,rose diagram generated with Dips software,decided the preferred structural face occurrence,analyzed the influence of rock mass structural face on rock mass,and provided basis for the stability analysis and evaluation for rock mass engineering and mining plan design.
