摘要
介绍了目前综合采煤提高块煤率的方法,提出了通过改变采煤机螺旋滚筒的结构,增加环形架、齿座架、锥形轮毂,实现了由外向里的最佳截割顺序,从而提高采煤机截煤块煤率的新思路,并做了较为全面的分析。
Introduced at present synthesizes mining coal to enhance the lump coal rate method,proposed through changes the coal mining machine spiral roller the structure,the increase toroidal frame,the tooth seat frame,the cone-shape wheel,has realized by the extroverted in best cutting order, thus enhances the coal mining machine coal cutting lump coal rate new mentality,and has made a more comprehensive analysis.
