摘要
分析了露天矿爆破时大块和根底产生的部位和原因，提高爆破质量就是减少大块和根底，提出了优化爆破参数、采用对角起爆的微差爆破、改善装药结构及采用挤压爆破等技术措施，并讨论了爆破器材的管理和爆破施工注意事项。
This paper analyses the position and the causes that produce large lump rockand foundation in the process of open-pit blasting. It points out that improving the qualityof blasting is to reduce the large boulder and foundation. Some teChnical measures such asoptimization blasting parameters, using oblique detonating millisecond blasting, improving loadedconstitution, taking extrusion blasting and so on, are presented in the paper. The points for attention of management of blasting material and blasting operation are discussed.These providesus with valuable method for further operation.
