摘要
二次动压巷道支护是煤巷掘进施工中的重要环节,支护质量的安全性能直接决定二次动压巷道的服务年限及使用。结合多年工作经验,探讨了阳煤集团开元公司9707进风巷设计过程中二次动压巷道的支护工艺优化及其应用方法。
The secondary dynamic pressure roadway support is an important link in the tunneling construction in coal roadway,and safety performance of support quality can directly determine the service life and use of the secondary dynamic pressure roadway. Combined with work experience for many years, this paper discussed support process optimization and its application methods of the secondary dynamic pressure roadway in the design process of 9707 intake airflow roadway in Kaiyuan Company of Yangquan Coal Industry Group.
