如何提高立井过空巷时的施工安全技术水平

Discussion on how to improve the construction safety technology level for the vertical shaft crossing the abandoned roadway

施工矿建工程回风立井期间,在物探后打钻探孔时经常会遇到有空巷,如何安全、高效的保证立井施工顺利穿越空巷显得尤为重要。主要介绍了注浆掘进的施工方法,对其施工要点进行了总结,并阐述了其施工安全注意事项,从而提高立井过空巷时的施工安全技术水平。

During the returning wind vertical shaft of the construction mine construction engineering, it always encounters abandoned roadway in drilling after geophysical prospecting. Therefore, it is rather important for how to safely and efficiently guarantee the vertical shaft construction smoothly crossing the abandoned roadway. The paper mainly introduces the grouting digging construction methods, summnarizes its construction points, illustrates the construction safety matters, so as to improve the construction safety technology level of the vertical shaft crossing the aban- doned roadway.
