摘要
工作面输送机的防滑、防歪架及防飞矸三大难题一直制约着我国大倾角综采技术的发展。通过许疃矿3234大倾角工作面的回采实践,总结出调整工作面伪斜回采、保持支架间平直紧密、安设防矸设施等一套提高大倾角工作面安全生产效率的方法。
The development of coal winning on fully-mechanized working face with large elevation angle is conditioned by three problems in China,which are anti-slipping of scraper conveyor,anti-falling of hydraulic supporter and preventing flying gangue.According to the practice on 3234 working face with large elevation angle in Xutuan Coal Mine,This paper summarized a method to improve safe production efficiency as follows：adjusting working face to realize oblique coal wining,keeping the supports parallel,standing-up and dense,installing preventing flying gangue facilities.
