锚杆支护在综采面收尾中的应用

Study on Bolt Support in Ending of Fully Mechanized Mining Face

综采支架回撤是综采面收尾的最后环节,也是关键环节,随时面临冒顶、通风流被隔断的威胁,文中着眼于保持顶板的完整性和稳定性,减少顶板事故,提高安全性,降低支护成本,提出了在综采面收尾期间运用锚杆支护的改革方案,并对其做了分析。

The supporter withdraw is the last step of ending of fully mechanized mining face, and also is the key step. It faces threats of roof fall and partition ventilating flow at any time in this process. Aimed at the integrity and stability of the roof, releasing the roof accident, improving security and reducing cost, the improved plan of application of bolt support during the ending of fully mechanized mining face is presented and analyzed.
