一、引言 煤矿自动化的发展在煤炭行业从劳动密集型向技术(知识)密集型的转变中起到了不可低估的作用,在提高生产效益和运行的可靠性,以及在煤矿的减员提效等方面都发挥了重要的、积极的作用。特别是由此而产生的一批机电一体化机械或设备以及系统,不仅将煤矿的技术水平提到一个新的高度,而且也极 I. INTRODUCTION The development of coal mine automation has played a role that can not be underestimated in the shift from labor-intensive to technology-intensive (knowledge-intensive) in the coal industry. In terms of improving production efficiency and reliability of operation, as well as efficiency reduction in coal mines, Have played an important and positive role. In particular, the resulting batch of mechatronic machinery or equipment and systems not only bring the technological level of coal mines to a new level, but also
