复式鑿岩是采鑛作业一项成熟重大的先进经验。几年来的经验证明,复式鑿岩不仅能够充分发挥机械效率能合理的利用工作时间,而且是提高产量、降低成本的关键问题。但必须认识,在这一新的生产方法中,每一个小组,应做好操作前和操作间的准备工作,提高工人的操作技术,就是推行复式鑿岩的先决条件。为了使这项先进经验,在有条件的鑛山很好推广,现将东北区各鑛的经验,加以综合,介绍给大家。
Multiple rock drilling is a mature and significant advanced experience in mining operations. Experiences over the past few years have proved that duplex rock drilling not only gives full play to the mechanical efficiency and makes reasonable use of working time, but also is a key issue for increasing output and reducing costs. However, we must recognize that in this new method of production, each group should prepare for the pre-operation and operation and improve the operation skills of the workers. This is a precondition for the implementation of multiple-rock drilling. In order to make this advanced experience well disseminated in qualified mines, the experience of various mines in Northeast China is now integrated and introduced to everyone.
