摘要： 针对传统大采高工作面过陷落柱技术工作面下沉量大的问题，开展大采高工作面过陷落柱技术研究，通过封
堵钻孔布置及注浆、过陷落柱支护，实现对大采高工作面的加固。实验证明，新的施工技术与传统施工技术相比，可有
效减少大采高工作面的下沉量，为大采高工作面施工提供安全、稳定的条件。

Abstract: Aiming at the problem of the large amount of subsidence in the technology of traditional working face with large mining
height passing through collapse columns, this paper studied the technology of the working face with large mining height passing
through collapse columns. Through the plugging drilling layout, grouting, and supporting in passing through collapse columns, the
reinforcement of the working face with large mining height was realized. Experiments have proved that the new construction technology
can effectively reduce the subsidence amount of the working face with large mining height compared with the traditional
construction technology, and provide safe and stable conditions for the construction of the working face with large mining height.

Key words: large mining height; working face; collapse column; subsidence amount
