48 m高烟囱定向爆破中的飞石控制

烟囱的定向爆破在爆破拆除中运用广泛。在工程实践中，可通过开设均匀对称的定向窗，再从爆破缺口尺寸、布孔位置、钻孔方向和孔网参数，科学合理地对爆破飞石进行控制，还可以对爆堆的检查进行分析定向，继而探讨出爆破中产生飞石的主要因素。

The Slungshot Control in the 48 m Tall Chimneys Directional Blasting

The chimney of directional blasting was widely used in the blasting demolition. In the engineering practice, people can set up the uniform symmetrical directional window, and then scientifical y control the blasting slungshot from the blasting hole size, hole position, dril ing direction and hole net parameter, and also can analysis of the orientation check, and finally explore the main factors of slungshot production in the blasting.
