前言美国矿业局正在开发一项制造计算机辅助的采煤机技术。这种采煤机将能自动跟踪煤层界面,并开采所期望的物质。若这项研究获得成功,它必将有助于提高开采的生产效率、工人的安全性和采煤的质量。
Foreword The United States Department of Mines is developing a computer-aided coal winning machine technology. The shearer will automatically track the seam interface and extract the desired material. If this research is successful, it will surely help improve the production efficiency of mining, the safety of workers and the quality of coal mining.
