综采液压支架回收顺序及工艺研究

Study on Recovery Sequence and Process of Fully Mechanized Hydraulic Support

香源煤业公司在1206综采工作面回撤过程中,对综采液压支架的回撤顺序及施工工艺进行了相关研究,回撤结果表明,与传统回撤工艺相比,回收时间节约60~70%,提高了支架回收的安全性。

During the retracting process of 1206 fully mechanized coal mining face, Xiangyuan Coal Company studied the retracting order and construction technology of fully mechanized hydraulic support. The retracting results showed that the recovery time saves 60 to 70% compared with the traditional retracting process, which improved the safety of the support recovery.
