摘要
根据影响高大烟囱定向爆破精度的因素 ,对烟囱爆破切口、振动、风力及烟囱损伤、内衬、烟道口等因素进行分析 ,提出了一些提高定向精度的方法。
There are many influencing factors for the precision of directional blasting of tall chimneys. In this paper, the influence factors, such as cut design of chimney, oscilation and wind effect, inner lineng condition, origenal chimney defects, are analysed. Some ways for increasing chimney directional precision are introduced.
