摘 要:采煤机的进刀方式是采煤工艺的重要组成部分,它直接影响到工作面的产量和效益。当采煤机型号和工作面长度确定后,如何选择采煤机的进刀方式,以缩短工作循环时间,进而提高综采工作面单产,便成了优化作业循环的主要问题。通过对比分析,文章得出了影响循环时间的三个重要因素,并对其进行了量化分析,给出了选择进刀方式的四个临界公式。The feed way of the shearer is the important component of coal technology, it directly affects the output and benefit of the coal mining face. After the type of the shearer and the length of the coal mining face be ascertained , how to shorten the working cycle time and improved the averaged yield of fully mechanized coal mining face by choosing the feed way of the shearer , have just becoming the principal problem of the optimization working circle. This article through the contrast analysis, has given out the three key factors which influence cycle time, has carried on the quantification analysis to it, and has produced the four critical formulas in choicing the feed way of the shearer.
