摘要
根据不同微差间隔时间对模型进行的超爆试验,说明矿岩产生有效破碎不是由于应力波的充分叠加,而是滞后于应力波的裂纹间相互交错、叠加、切割的结果。不同炮孔周围裂纹的适量产生与发展,是引起岩石有效破碎的真正原因。
The rock blast test at the tiny interval of different time shows that the e ffective crush is not directly the folding of the stress wave,but stays behind the intersect,folding and cu tting of the stress wave.The form and devel-opment of the blast hole cracking is t he main reason which leads to the effe ctive crush.
