中文摘要：

甘肃北山坑探设施为我国高放废物地质处置工程研发及建设阶段里程碑式的设施。基于光面爆破施工方法,设计了甘肃北山坑探设施项目光面爆破的爆破参数,得到了适宜于本项目的爆破实施方案,进而实施了在不同爆破参数（周边孔间距）的光面爆破,验证了光面爆破参数的科学性。同时,需指出的是,钻爆施工涵盖多种不同的爆破参数,影响因素众多,爆破试验获取的爆破数据仅仅是对不同周边孔间距的初步探索。研究成果可对后续工程开挖提供相应的试验数据与理论支撑,其对于深部地下工程的爆破开挖及高放射性废物的深地质处置有一定的理论指导意义。

英文摘要：

The Beishan pit exploration facilities in Gansu province is the landmark facilities of the research and construc-tion phase of the high-level radioactive waster geological disposal engineering in our country. Based on the smooth blasting method,the blasting parameters of the Beishan pit exploration facilities have been designed,which is much more suitable to this project. Furthermore,the smooth blasting effects is analyzed under the different kinds of blasting parameters （spacing of periph-eral holes）,the scientific of smooth blasting parameters is verified. In advance. It should be noticed that,blasting method in-cludes numerous blasting parameters,which interaction each other. Those blasting parameters obtained just on the spacing of peripheral holes,and the results and theoretical knowledge could be applied to the blasting and excavation of the deep geo-en-gineering and the high-level radioactive waster geological disposal.
