我部坑探工作从推广使用凿岩台车以来，对提高掘进效率、改善工作条件、加快地质勘探速度以及缩短勘探周期都起到了一定的作用。为了适应凿岩台车的需要必须加快凿岩爆破工艺方面的研究，有了先进合理的工艺，才能发挥出台车的效能。使用凿岩台车时，为了增加生产时间，减少放炮、通风、排烟非生产时间，提高爆破效率和循环进尺，一般都采用深眼爆破。进行深眼爆破不利于破碎岩石的困难因素较多，很难保证炮眼的准确度，又兼采用深眼爆破与过去爆破方法不同，必须反复进行实践，从实际工作中不断试验、研究、总结。进行深眼爆破必须研究以下问题：
Since the popularization of the use of rock drilling rigs, the pit excavation work has played a certain role in improving tunneling efficiency, improving working conditions, accelerating geological exploration speed and shortening the exploration cycle. In order to meet the needs of rock drilling rig blasting technology must accelerate the research, with advanced and reasonable technology, in order to play a car performance. When using rock drilling rigs, deep-hole blasting is generally used to increase production time, reduce blasting, ventilation, exhaust non-production time, improve blasting efficiency and cycle footage. Deep blasting is not conducive to rock crushing more difficult factors, it is difficult to ensure the accuracy of the blasthole, and both the use of deep-blasting and blasting the past different methods must be repeated practice, from the actual work of continuous testing, research and summary. Deep-hole blasting must study the following questions:
