东曲矿掘进工作面临时支护的改进

Improvement of the Temporary Support of Tunneling Face in the Dongqu Mine

在对东曲矿掘进工作面当前使用的几种临时支护存在问题分析的基础上,有针对性地进行了改进,研制出一种适应当前掘进工作面的临时支护方式。该临时支护方式既保障了掘进工作面的安全,又提高了掘进效率。

Based on analysis of existing problems in several temporary support used at present in tunneling face of Dongqu Mine, we makes corresponding improvement on the temporary support means in the light of the existing problems, develop a temporary support means adapted to present tunneling face. The temporary support means not only ensures the safety of tunneling face but also increases tunneling efficiency.
