煤矿掘进工作面过陷落柱主要施工技术探析

Discussion on the Main Construction Technology of Passing through the Collapse Column in Coal Mine Driving Face

在煤矿掘进时经常会遇到陷落柱,给安全掘进构成了巨大威胁。为了保证掘进能顺利地通过陷落柱所在的区域,必须采取相应的措施。针对陷落柱区域存在的施工安全问题,应用了加强支护技术和探测技术。分析了过陷落柱所应用的具体的支护技术和施工技术,以期为煤矿掘进工程技术人员提供一定的参考。

In coal mine driving,there are often collapse pillars,which pose a great threat to the safety of driving.In order to en-sure that the excavation can smoothly pass through the area where the collapse column is located,corresponding measures must be taken.In view of the construction safety problems existing in the collapsed column area,the strengthening support technology and detection technology were applied.This paper analyzed the concrete support technology and construction technology during passing though the collapse column,in order to provide certain reference for the technical personnel of coal mine driving engineering.
