影响光面爆破的因素

The Factors Influencing the Smooth Wall Blasting

隧道施工的控制主要在开挖上,控制好隧道超欠挖,后序初期支护的平整度、质量都能得到有效的保证,并且有显著的经济效益,光面爆破效果好坏是衡量隧道开挖成败的重要依据,影响光面爆破的因素:既有地质条件为主的主观因素,又有钻眼精度、爆破技术、爆破施工参数为主的客观因素,在主观因素无法改变的情况下,客观因素的相应的调整就显得格外重要。

Control of tunnel is mainly on excavation. The good control of the tunnel overexcavation, the order of the formation of primary support, quality assurance can be effective and have significant economic benefits, good or bad of smooth blasting is important measure of success or failure of tunnel excavation. The factors that affect the smooth blasting include geological conditions both subjective factors and the objective factors of precision drilling and blasting techniques, blasting the main construction parameters. When the subjective factors can not be changed, the corresponding adjustment of objective factors is particularly important.
