烟囱定向爆破切口设计与实践

Blast Cut Design and Practice of Chimney Directional Blasting

爆破切口设计是决定烟囱定向爆破是否成功的关键,在复杂环境和安全要求很高的情况下,爆破切口经验参数设计往往带有模糊性和不确定性,需要进行校核。主要从切口形式、角度、高度分析烟囱定向爆破的理论依据。结合工程实例,对设计的爆破切口参数进行校核,并对倒塌过程进行模拟仿真。

The blast cut design is key to the directional blasting of chimneys. In complex surroundings and high safety requirement ,the empirical parameter design of blast cut is always fuzzy and uncertain, so which needs to be checked. This paper mainly analyzed the basis theory of chimney directional blasting on the blast cut shape,angle and height. Combined with engineering practice,the parameters of blast cut was checked and the collapse process was simulated.
