综采工作面安全优质快速回撤技术

Fast Withdrawing with Safety and High Quality at Fully Mechanized Coal Face

在煤矿生产过程中,随着机械化程度的提高,大功率、大吨位设备的出现,采煤工作面回撤工作日趋重要,回撤工作进行的快慢,直接影响到采煤工作面的正常接续。如何实现综采工作面安全优质快速回撤,确保采煤工作面的正常接续,是我们一直探索的课题。文章通过对鸡西矿业集团杏花煤矿东三一条带综采工作面快速回撤的总结分析,为相同条件下综采工作面安全、快速回撤提供了经验。

In the mine production process, with the increase of mechanization degree, the emergence of high power and large-tonnage equipments, the coal face retracement becomes more and more important, the speed of withdrawing directly affects the normal continuation at the coal face. How to realize fast withdrawing with safety and high quality at the fully mechanized coal face in order to ensure the normal continuation of the coal face is a exploring subject. The fast withdrawing at the fully mechanized coal face in east No.31 zone was summed up and analyzed. The experience can be provided for safe mining and fast withdrawing at the fully mechanized coal face under the same condition.
