凿岩工作是在露天、地下采矿和掘进中采用爆破法的最重要的先行工序。凿岩工作的速度与质量,极大地影响着爆破作业,因而是提高采矿和掘进生产率的重要关键之一。世界各国的采矿技术界和设备制造商都对此给以高度的重视,并投入了巨大的人力与物力,对凿岩技术开展了广泛深入的试验与研究。最近几年来,取得了许多令人瞩目的新进展,大大促进了采矿和掘进技术的提高,使生产效率迅速增高,费用显著降低,引起了世界采矿掘进界人士的注意。
Drilling work is the most important first step in the opencast, underground mining and excavation blasting method. The speed and quality of rock drilling work, which greatly affects blasting operations, is therefore one of the key points to improving productivity in mining and driving. Mining technology community and equipment manufacturers all over the world attach great importance to this, and invested enormous human and material resources, carried out extensive and in-depth drilling technology research and research. In recent years, there have been many remarkable new developments that have greatly contributed to the improvement of mining and excavation technologies, the rapid increase of production efficiency and the significant reduction of costs, attracting the attention of the world’s mining boring people.
