浅谈机掘临时支护技术在凤凰山煤矿的应用

Application of temporary support technology for mechanized excavation in Fenghuangshan Coal Mine

通过对凤凰山煤矿机掘工作面曾经使用过的几种临时支护方法进行分析,最终形成一套机掘托梁器临时支护技术。该机掘临时支护技术既保障了机掘工作面的安全,又提高了掘进效率,可供类似矿井借鉴。

By analyzing several temporary support methods used in the tunneling face in Fenghuangshan Coal Mine,a set of temporary support technology based on joist device was improved. The temporary support technology not only ensures the safety of the driving face,but also improves the tunneling efficiency,which can be used for reference in similar mines.
