石方明挖采取的爆破工艺是一项成熟的石方开挖技术,但在不同的工程施工中,应根据不同的岩性强度、岩层分布及风化情况等地质条件,根据不同的山势、地形及不同的设计开挖线的要求,制定适合的爆破工艺设计,并对其进行安全验算,满足开挖的经济性、可实施性及安全性等要求。文章简要介绍了河口村水库大电站厂房边坡爆破开挖施工的爆破设计及安全验算,重点阐述了爆破参数的确定及安全验算对周边环境的影响,从而体现出在石方爆破开挖中爆破工艺设计及安全验算的重要性。
The blasting process adopted by Shifang mound is a mature excavation technology of rock excavation. However, in different engineering construction, according to different geological conditions, such as lithology intensity, rock formation distribution and weathering conditions, according to different mountain topography and topography Different design requirements of the excavation line, to develop a suitable blasting process design, and its safety checks, to meet the economy of excavation, feasibility and safety requirements. This paper briefly introduces the blasting design and safety check for the blasting excavation construction of the powerhouse of Hekou Village Reservoir. The emphases are the determination of blasting parameters and the influence of safety check on the surrounding environment, The importance of process design and safety checking.
