正确选择切割阵列中盘形滚刀的最优间距,是巷道掘进机设计中的一个最重要因素。巷道掘进机的性能和运转费与此值密切相关。为了确定最优的间距与钻进速度比(S/P),用锐盘形滚刀和钝盘形滚刀进行了大量的研究。对于锐滚刀,最优的S/P值介于 Correct choice of the optimal spacing of the disc cutter in the cutting array is one of the most important factors in the design of roadheading machine. The performance and running cost of roadheading machine are closely related to this value. In order to determine the optimal pitch-to-penetration ratio (S / P), a large number of studies have been conducted with sharp-edged hobs and blunt-disc hobs. For a sharp hob, the best S / P value is between
