高边坡危岩体爆破及其控制技术

Blasting and Controlling Techique of High and Steep Rock Slope

高边坡危岩体的爆破处治,区别于普通的爆破作业,而有其特殊性和复杂性。爆破设计和施工时应在充分了解危岩体的地质结构特征和周边环境的条件下,制定切实可行的爆破施工方案和有效的防护措施。基于石板房危岩体的结构特征和环境条件,介绍了控制爆破的设计原则,以及所采用的预裂和松动控制爆破方案,提出了控制爆破飞石和滚石的技术措施。通过采用控制爆破的方法,排除了危岩体对山下居民的危害和公路通行的影响,达到了预期的效果。

Blasting and controlling technique of high and steep rock slope, differing from common blasting,have their special complexity. While,in the course of blasting design and implementation,the rock geology characteristic and environment should be sufficiently realized, and the scheme of blasting and valid protection measures should be established. According to the structural characteristic of rock slope and environment of Shi Ban-fang,this paper introduces the principle of controlled blasting and the scheme of pre-splitting blasting and loose blasting. Some technique measures of how to control blasting flying rock and rolling stone are introduced. The methods above are used in realistic engineering and ideal result is obtained.
