摘　　要：为提高沿顶掘进综放工作面机头、机尾底部三角煤的回收率,古汉山煤矿对1606综放工作面排头液压支架采取了顶梁加高的技术改造措施。结果表明,通过对排头支架的改造,提高了运输巷、回风巷的支护高度,降低了支架卧底弯曲段的长度,增加了底部三角煤的回收率。In order to improve the recovery rate of triangular coal at the bottom of the machine head and tail of the fully mechanized top coal caving face along the top,Guhanshan Coal Mine adopted the technical transformation measure of heightening the top beam of the hydraulic support at the row head of the 1606 fully mechanized top coal caving face.The results show that through the transformation of the row head support,the support height of the transport roadway and return air roadway is increased,the length of the undercover bending section of the support is reduced,and the recovery rate of triangular coal at the bottom is increased.

关 键 词：沿顶掘进 排头液压支架 加高顶梁 三角煤回收
