By using dynamic photoelastic technology, the control effect of the leading hole to the cutting crack extension was investigated in cutting blasting used in some protective stone materials mining. The orientation control mechanism of several arrangments of uncharged boreholes with boreholes often used in ehgineering was analysed.

By using dynamic photoelastic technology, the control effect of the leading hole to the cutting crack extension was investigated in cutting blasting used in some protective stone materials mining. The orientation control mechanism of several arrangments of uncharged boreholes with boreholes often used in ehgineering was analysed. The dynamic stress distribution near the leading hole was studied when stress wave is incident upon the leading holes. It was found that the dynamic tensil stress concentrations near the eadge of the leading holes formed both by the incidence of the stress wave and the quasi-static stress field produced by high pressure gas in boreholes make the cracks, along the direction of two holes, produce and extend easily and previously, so that the main cutting cracks can be formed to control cutting results well.

采用动态光弹性技术,探讨了在保护性石料开采中使用的控制切割爆破技术中导向空孔的存在对切割缝的控制作用,分析了工程中常见的几种空孔配置形式的导向机理。考察了爆破应力波入射空孔时空孔周边的动应力分布情况。结果发现,正是由于应力波在空孔周边附近及炮孔爆炸时高压气体的准静态共同作用形成的动拉应力集中使沿炮孔与空孔连心线方向的裂纹优先扩展形成切割主裂缝,从而达到控制切制的目的。

The essence of Multirow Same-segment Blasting Technology in Shizishan Copper Mine is a combination of short millisecond and random simultaneous blasting acts. Its main benefit is the simplification of blasting and corresponding mining operation.The blast mechanism of short millisecond is similar to that of the segment millisecond blast, but its interaction of stress wave and explosion gases is more complete, the crack formation and its interface branching is more obvious. For random simultaneous blasting action, owing to the explosion energy releasing to rock simultaneously and interaction of stress wave, high stress area will be formed on the link line between the holes,so the macro-crack is easily formed along this line. But on the other directions of holes, the effect of this explosion energy releasing simultaneously is not evident.

狮子山铜矿多排同段爆破的实质是“短时微差”起爆和“随机同时”起爆爆破作用的复合,其主要特点表现为爆破工艺及相应的采矿工艺得到简化。“短时微差”起爆的爆破作用机理类同于排间段别微差爆破,但爆破应力波的叠加作用及爆炸气体作用更加充分,爆破裂纹的形成、交叉分枝现象更为普遍。“随机同时”起爆,炸药能量同时对岩石释放,极易沿孔间连线形成足够宽的贯通裂纹,但在炮孔的其他作用方向上,这种炸药能量同时释放对岩石的破碎作用没有明显效果。
