摘要
以中深孔大区微差爆破技术在安徽省埠宁高速公路路堑开挖中应用为例,讨论了V型拉槽爆破的炮孔布置、中深孔大区微差爆破参数选择、非电起爆网路设计和爆破安全校核等技术问题。爆破试验表明,在宽间距小抵抗线爆破中采用固定排间距、调整孔距的炮孔布置方法对于不规则自然地形条件下的深路堑爆破是科学和有效的,可供类似的路堑爆破设计与施工借鉴。
An example of the application of large-scale millisecond multiple-row holes blasting technology in cutting excavation blasting of the funing highway is introduced, and the designs of blast-hole arrangement, blasting parameters, initiating network,stemming and safety proofreading are mainly presented. Some experiences obtained are useful for the similar projects.
