摘要空气间隔装药预裂爆破作为一项新型轮廓爆破技术，其对岩体的损伤特性严重影响了技术的推广应用。采用现场试验与数值计算相结合的方法，对经山寺铁矿空气间隔装药预裂爆破试验的岩体损伤分布特征进行比较分析。结果表明，空气间隔装药预裂爆破的岩体损伤分布特征与传统预裂爆破存在明显的差异，装药段存在明显的粉碎破坏区，爆破损伤区的范围显著大于空气段以及传统预裂爆破，但在岩体较完整处，空气段的岩体损伤相对不明显。为了控制岩体损伤效应，装药段采用反向起爆的方式以及使用径向不耦合的筒状药卷，可以优化空气间隔装药预裂爆破效果。

Abstract：Presplitting blasting with air-deck charge has been applied as a new contour blasting technique，but the rock damage characteristics of which has severely limited its application prospect. The air-deck charge presplitting blasting experiment has been conducted in Jingshansi iron mine. And the rock damage characteristics was studied by using a method of combining acoustic detection with numerical simulation. It is reported that there were significant differences between air-deck charge presplitting blasting and traditional presplitting blasting in the distribution of rock damage. The damage zone size of the rock near the charging section was much larger than that near air section，which was also larger than the rock damage zone size in traditional presplitting blasting. There was smash district in remaining rock near the charging section. While in some intact rock mass，the damage zone of the rock near air section was not obvious. Taking advantage of indirect initiation and casing charge structure could be benefit to decreasing the rock damage effects of presplitting blasting with air-deck charge.

Key words： rock mechanics air-deck charge presplitting blasting rock mass damage acoustic detection
