在过去几年中,地下装载作业机械化程度越来越高,因此凿岩作业也不得不跟上步伐。用气腿式凿岩机进行凿岩通常被认为是凿岩机械化的第一阶段,在这个阶段中广泛采用压缩空气。在本世纪60年代,出现了气动凿岩钻车,随后才出现今天的液压凿岩装置。大约从1975年起,“第二代”液压凿岩机的出现使凿岩速度比气动凿岩钻车高一倍.用双臂液压设备代替四臂气动凿岩设备成为可能。今天,我们不但可以看到综合控制设备,而且可以看到积木化程度更高的凿岩设备的研制。采用积木化后,只要把基本凿岩
In the past few years, underground loading operations have become increasingly mechanized, so drilling operations have to keep up. Drilling with gas-legged rock drills is generally considered the first phase of rock mechanization, where compressed air is widely used. In the 1960s, pneumatic rock drilling rigs appeared, and the hydraulic rock drilling device of today only emerged. The emergence of the “second generation” hydraulic rock drills has doubled the rate of rock drilling rigs since 1975. It is possible to replace the four-armed pneumatic rock drilling rig with a two-arm hydraulic rig. Today, not only can we see integrated control equipment, but we can also see the development of more advanced rock drilling equipment. After the use of building blocks, as long as the basic rock drilling
