在对不同掏槽形式进行对比分析的基础上,结合工程实例,试验分析了不同掏槽形式下的爆破效果,认为斜眼掏槽和直眼掏槽都存在各自的缺陷,提出采用和推广准直眼掏槽方式的建议。
Based on the comparative analysis on different cutting mode and according to the engineering case, test analysis was made on the blasting effects of different cutting mode. It is held that both inclined underholing and parallel cut have defects, the suggestion was put forward for adopting and wildly using quasi-parallel cut.
