| 摘 要： | 炮掘爆破对围岩破坏严重，对巷道支护效果及安全造成很大的影响，在不改变支护方式前提下，最大限度地减小松动圈厚度，实现巷道支护效果质的提升。控制爆破适合在软岩巷道，尤其是在煤巷、半煤巷掘进中应用，可以使劳动组织不断优化。

| Abstract: | Blasting reaming damages the wall rocks and reduces the safety of tunnel retaining. Minimizing the thickness of loose ring at maximum can enhance tunnel retaining effect. Control blasting technique fits to soft rock tunnel, especially to coal tunnel and half-coal tunnel. |
| |
| Keywords: | soft rock tunnel medium deep hole control blasting retaining technique application study |
