提高金堆城南露天爆破质量的实践

通过理论分析和现场试验,查明了南露天爆破根底和大块的产生原因;根据南露天工程地质特点和生产实际状况,制定相应的爆破根底及大块综合治理技术措施,使金堆城南露天采场的根底和大块率降至正常生产允许的范围,提高了爆破质量和铲装效率,为南露天剥离工程生产效率的提高和南露天生产爆破设计提供技术依据。

Practice of improving blasting quality in south open-pit of Jinduicheng

The reasons of producing toe rock and boulder in blasting of south open-pit were found out based on theoretical analysis and field test.According to the geological characteristics and production status of south open-pit engineering,the corresponding comprehensive treatment measures of toe rock and boulder were made.The measures enable the toe rock and boulder frequencies decreased to allowance range of normal production,improved blasting quality and shoveling efficiency,and provided the technological basis ...
