摘要
在某水利建设工地进行的斜坡道控制爆破开挖严重受到周围环境的制约和影响,对此,本文综合运用了光面爆破、预裂爆破、松动爆破及城市控制爆破中的研究成果,设计和确定斜坡道控制爆破开挖的合理炮孔布置参数、单段起爆药量、装药结构、起爆顺序及爆破防护措施等。实践结果表明,在防护手段不是很完备的水利工地,通过周密考虑和精心设计,岩体爆破开挖是可以达到一定控制目的的。
The controlled blasting excavation of a slant road in a hydraulic construction site is seriouslyrestricted and influenced by surroundings. In this paper, according to research results in smoothcontour blasting, pre - slit blasting, rock - free blasting and urban controlled blasting, the reasonable hole Parameters, charging amount per delay, charging structure, detonating order andblasting - protecting measures, etc. are designed and determined. The practical result shows thatalthough blasting - protecting means is not very Perfect in a hydraulic construction site, it is possible to realize some controlling purpose through carefull consideration and design.
