目前各勘探队在爆破技术上存在比较普遍的问题，是不正常爆破现象，这不仅降低爆破效率，同时也严重地威胁着工人的生命安全。因此，努力预防不正常爆破现象的产生，是当前钻眼爆破工作者刻不容缓的任务，同时也是改进爆破技术和提高勘探坑道掘进速度与安全生产的主要关键。 At present, each exploration team has a relatively common problem in blasting technology, which is an abnormal blasting phenomenon. This not only reduces blasting efficiency, but also seriously threatens the life safety of workers. Therefore, efforts to prevent the occurrence of abnormal blasting are the immediate tasks of current drilling and blasting workers, and are also the key to improving blasting technology and improving excavation speed and safety in exploration tunnels.
