在矿山开拓工程中,由于现代化的第二代液压凿岩台车已有足够的功率和工作可靠性,因此,凿岩已不再是掘进循环的薄弱环节。同样,在采矿深孔凿岩中,已不仅靠最大限度地提高凿岩速度,同时钻具磨损要保持经济合理限度内,来取得最佳经济效益。计算机控制的浅孔和深孔凿岩台车的最近投入使用,已对凿岩循环的总效果和开挖成本产生巨大的影响。然而,正如不可能期待由计算机设计凿岩台车那样,凿岩实施全盘自动化并不切合实际。在计算机控制凿岩的隧道掘进中,凿岩工在控制掘进质量方面仍将起重要作用。在隧道的掘进过程中,也需要凿岩工调节凿岩参数和分析各个参数对整个掘进过程的影响。现在已称这种凿岩方式为计算机辅助凿岩(CAD)。
In the mine pioneering project, because the modern second generation hydraulic rock drilling rig has sufficient power and operational reliability, drilling is no longer the weakest link in the excavation cycle. Similarly, in mining deep hole rock drilling, the best economic benefits have been obtained not only by maximizing rock drilling speed, but also by keeping the wear of drilling tools within economically reasonable limits. The recent commissioning of computer-controlled shallow and deep hole rock drilling rigs has had a huge impact on the overall effect of rock drilling cycles and on the cost of excavation. However, just as it is impossible to expect a computer to design a rock drilling rig, it would not be practical to implement a complete automation of rock drilling. In computer controlled rock drilling tunneling, rock drillers will still play an important role in controlling the quality of tunneling. In the process of tunneling, the drillingman is also required to adjust the drilling parameters and analyze the influence of each parameter on the whole driving process. This method of rock drilling has now been described as Computer Aided Rock Drilling (CAD).
