摘要
矿区深部工程地质调查与评价是“九五”国家重点科技攻关项目“新城金矿复杂条件矿床采矿方法研究”的一项重要内容。本文主要介绍矿区节理裂隙调查、统计的方法和结果 ,依据调查结果对节理裂隙的分布规律及其与地下巷道、采场围岩稳定性的关系进行了分析。根据矿区工程地质、水文地质和节理裂隙发育调查统计资料 ,矿区地应力测量和矿岩岩石力学性质试验结果等 ,采用CSIR地质力学分类方法 ,对矿区分布的主要岩组进行的岩体质量分级评价。
Investigation and analysis of engineering geological conditions in Xincheng gold mine is a important work for mining design in deep position of Xincheng gold mine.This paper introduces methods and results of investigation on status and distribution regularity of joints in deep position of the mine.Analysis of relationship between joint condition and stability of surrounding rock of openings and mining areas is completed.Using CSIR geomechanical classification method,assessment on rock mass quality in the mine is provided.
