摘要
通过对三角柱直眼掏槽爆破进行试验研究 ,认为爆破槽腔的形成过程可分成两个阶段 ,即岩石破坏阶段和破碎岩石抛出阶段 ;进而 ,依照岩石压缩破坏与剪切破坏的力学准则 ,导出三角柱直眼掏槽炮眼间距与装药系数的计算式 ;根据计算结果 ,在井下巷道工程实际应用中进行对比 ,证实了它的可靠性。
Through research on tunnel-based triangle burn cut by in-situ test,it is assumed in this paper that the process o f cavity formation by explosive contains two successive stages,rock being broken and being thrown out.In accordance with mechanics rules on rock break in compre ssion and in shear,the calculation formulas of space and the charging coefficien t of parallel holes are deduced.The values from these formulas have been proven applicable in engineering design.
