回采动压下软岩巷道全断面封闭支护技术研究

Study on full face sealed support technology of soft rock roadway under dynamic mining pressure

软岩巷道支护技术一直是煤矿生产中研究的重点,尤其是在回采动压下施工巷道,支护不当将导致巷道大量返修,给安全、生产等带来了很大的隐患,因此寻求一种理想的支护方式支护动压下的软岩巷道已成为新的研究课题。开滦荆欢矿业分公司东井采用全断面封闭支护技术收到了较好效果。

Soft rock roadway support technology has been the focus of research in coal production,especially in the tunnel construction under dynamic pressure.Support impropered will result in substantial rework roadways,and it has brought a lot of hidden dangers to security and production,so find an ideal way to support the soft rock roadway under dynamic pressure has become a new research topic.Full face closed supporting technology has been used in Kailuan Jinghuan mining branch and obtained better results.
