摘要
介绍了东曲矿18107综采工作面收尾时,在顶板破碎带使用了化学注浆加固技术,顺利实现了工作面的收尾扩通道,并从支护方面进行了研究,为以后综采工作面过类似破碎带积累了一定的经验。
Introduces uses chemical grouting reinforcement technology in broken roof zone when ends in 18107 fully mechanized working face of Dongqu coal mine,realizes successfully the ending expanding tunnel of working face,and researches the supports,accumulates certain experiences to fully mechanized working face in similar broken roof zone for the later.
