Discussion and Research on Quick Retracement Key Technologies at Fully Mechanized Caving Face

摘要: 综放工作面的回撤，是矿井实现高产高效和安全生产的重要环节，同时也制约着综放工作面的单产水平。以云盖山煤矿二矿22201综放工作面回撤为例，对综放工作面的快速回撤关键技术进行探讨和研究。

Abstract: Retracement at fully mechanized caving face is an important part of mine to achieve high-productivity and high-efficiency and safety production, which also restrict the yields of fully mechanized caving face. This paper takes retracement in 22201 fully mechanized caving face as example, discusses and researches quick retracement key technologies at fully mechanized cavinging face.
