阶梯孔边坡控制爆破对司家营采场边坡治理效果的探讨

摘要

边坡靠界爆破是司家营北区分公司生产过程的重要环节, 为了更好的实现预裂爆破效果, 在原来预裂爆基础上, 对坡面位置研究实施阶梯孔控制爆破.介绍了工程概况, 并对东帮及北帮阶梯孔控制爆破应用及效果进行了阐述.%Boundary slope blasting is an important link for production in Sijiaying North Branch.To achieve the best presplitting blasting effects, apart from adopting pre-spitting blasting, positions of slopes are studied and bench hole slope-control blasting is carried out.General conditions of the project are introduced, and application and effects of bench hole control blasting for east slope and north slope are discussed.
