摘要
在 32 9国道K110 +4 6 0 -K110 +740段路堑爆破开挖中 ,采用常规的浅孔控制爆破与药壶控制爆破相结合的施工方法。当开挖厚度小于 2m ,或安全要求特别高的作业点 (如高压线下 ) ,采用浅孔爆破 ,并利用浅孔爆破为药壶爆破施工开创工作面与自由面。本文介绍了浅孔爆破和药壶爆破参数的选择、扩壶工艺以及有关两种爆破方法综合应用的经验和认识。
In excavation of the cutting in K110+460-K110+740 section of National Highway No 329,a constructing method of combining conventional short hole blasting with springing bench controlled blasting was used In some operation points with an excavation thickness of less than 2m or a high safety demand,for example,under high voltage power line,the short hole blasting was used Also,the short hole blasting was used for creation of a working face or free face for springing blasting In this paper,the selection of parameters for short hole blasting and springing blasting,springing technology as well as the experience and knowledge about comprehensive application of the two blasting methods were presented
