| 摘 要： | 针对张坝沟石灰石矿露天边坡倾斜孔光面爆破,在爆孔旁侧钻眼测试声波以测试岩石的损伤程度,结果表明爆破影响达1.5m左右。文中还通过水泥砂浆模型实验得出了孔壁应力、应变和压力分布,结果表明炸药紧贴孔壁的压力远大于其余方向的压力,为改变装药结构提供依据。

| Abstract: | Based on the slope of Zhangbagou limestone mine,the rock damage are tested by ultrasonic testing.The result shows that rock damage by smooth-surface blasting arrive about 1.5 meter.The concrete model experiment are made,the result shows that the bore wall stress of cling detonator is bigger than others.The result can provide evidence for change charge pattern. |
