摘要
介绍了白马铁矿1600主平硐ZK2+385 m段岩爆现象及特征,并对岩爆机理及成因进行了分析,从降低围岩地质应力、改善岩爆地段围岩特性、加强岩爆地段隧道支护等方面,制定了岩爆施工对策。通过实施,深埋高地应力岩爆段顺利施工完成。
This paper introduces the phenomenon and characteristics of rockburst in ZK2+385m section of1600main adit of Baima Iron Mine,analyzes rockburst mechanism and its causes,and formulates rockburst construction countermeasures,starting from aspects of reducing surrounding rock geology stress,improving surrounding rock characteristics at rock-blasting section,and strengthening tunnel support at rock-blasting section.Through the implementation,the completion of deep-buried high-stress rock burst section was completed smoothly.
